placement question of c programming

Off Campus Written Test conducted in 3 at BangaloreThe test comprises of 2 sections: 1. Technical ( C ) & Technical Subject- 60 mins, 60 questions 2. Logical Reasoning.. - 30 mins,17 questions.... ==> Questions in C were mostly from "pointers in c" and "test ur C skills" by Yeshwant Kanetkar... C questions based on command line arguments, data structure ( BST, tree traversals). All the questions were like " what is the output of the following program segment" and in many questions 3rd and 4th choices were (c) compilation error and (d) compilation, warning, runtime error.... Heard they are asking abt- ptr, string, arr, preprocessor, data structures etc.. C test was pretty ok pass by value, pass by reference etc. questions were asked The general test was pretty tough, they ask u fourier transforms,harmonics,Barkhuasen criterion,virtual memory,Whether FIFO is better than LRU etc. 4 questions were from fourier transforms the duration was 60 mins and no negative marking C basics 10 questions ,very easy.Given a program and asked the output-type questons.from pointers 3-4 questions are there. 2)reg subject:very very easy:some from digital(on nand gates. Jk flip flop),from Information theory and coding,some from Micro processors. In Logical Reasoning all the 17 questions were paragraphs (argument) of 5 to 6 sentences...five sentences (choices) will be given below and questions were asked like " which of the five if true will weaken or supports the argument above .." :- R. S. Agrawal LR is sufficient SASKEN PAPER HELD ON 9th AUG at 2:30pm-------------------------------------------------------------- The questions were like this.------------------------------The text consists of two parts1) C test2) CSE01 TestDuration: 1hr--------------------------------------------------------------- 1) C test -10 questions- Some questions were as follows, remember only a few.a) What is the parameter passing mechanism to Macros Called?b) void func(int x,int y){x=3;y=2;} main(){int i;func(i,i);print(i);}If the output must be 2 what is the parameter passing mechanism called?c) which of the following code will swap the two numbers? -3 choices was givend) which of the following is illegal for the program?main(){char const *p='p';} 1)p++ 2) *p++ 3)(*p)++ 4) alle) what is the output of the following programvoid print(int ** arr){print("0 %f, 1 %f, 2 %f ",arr[0][0],arr[0][1],arr[0][2]);}main(){int a[][]={ {1,2,3},{4,5,6}} int ** arr=a;print(arr);arr++;print(arr);}f) which of the following code swaps the two numbers.- 4 choices were giveng) if the string " this is a " is present in the code of a function such as 'void func(void)' where will the variable stored in the memory.a) in the stack b) heap c) code or text segment as per implementation d) created when func is called, stored in function stack space and destroyed as it goes out . 2) CSE01-15 questionsIn this section there was question from LD-gates, JK flip flop, sampling rate and few otherthen there was a few from OS - don't remember the questions. INTERVIEW In the interview, they asked about Stacks, Queues, Linked lists, Binary Trees. Few questions I remember are: 1) If u have a linked list library, how do u design stack and queue using it; write pseudocode. 2) What are static variables and functions? 3) Write code in C to count the number of 1s in a character (1byte). 4) What is pre-order, post-order, in-order; write code to print post-order. 5) Can u construct a binary tree given its inorder and postorder details. Is it neccessary or sufficient to construct tree. Asked an example to do in both ways. 6) If recursion is not used to print post order, what other data structure u use (ans: Stack). 7)Can u use stack always in place of recursion? (ans: Yes) 8) What are meta characters? 9) Write a piece of code to insert a node in a linked list. 10) About malloc. 11) About Operating System - Semaphores 12) About Computability (eg:- finding infinite loop), Complexity of algorithms 13) What does compiler and assembler do? They asked grep command in Linux. How do u search '\n', using grep, in a file. They may ask some other commands if u say u r familiar and recently been using linux. About Networks? OSI reference model. what does transport layer do? TCP belongs to which layer? IP belongs to which layer? Where is error correction done? What is a connection oriented/ connection less transmission? What is meant by reliable transmission protocol? why is it called so? What is flow control and where it is done? About ur project? Asked me expalin about the project in brief. If u don't know anything, say it sincerely. U cannot bluff them. I too spoke to them sincerely. They were cool. U need not get tensed. They won't attack you. Just they want to know ur hold about the subject. Next Paper NOTE : Answer May Not be Accurate So Get An Idea of Questions.

Tech interview questions------------------------ They will ask about the project.They will ask general questions about it and most probably will not go intothe implementation part of it.So one must have a general idea about the project done. Interview is mainly based on Data Structures.Somequestions are as follows:-- What is a tree,its application,order for insertion,deletion and traversal with worst case analysis.- What is a graph,its application.- Height of a tree- Balanced tree and how to balance a tree- Minimum Spanning Tree- Dijikstra's, Prim algorithms- Define a structure for a linked list.- Binary search and its analysis- Heap sort and its analysis- What is a heap and its application- Cache and its working- Memory(IO mapped)- Recursive fns and types, its adv and disadv.- Compiler(grammar) *****C debugging questions like (1)What is the problem with the following code int * f(int a){int i;i=a;return(&i);}Ans-> We can't return address of auto variable as it is allocation is made in stack which is deallocatedwhen the function returns. (2)a.h b.c c.c d.cint i=0 #include"a.h" #include"a.h" extern inti;void main{.....} b.o c.o d.o Compilation Phase Linked to get exe. Will there be any problem in any phase.If yes then where and what? In linking phase as there will be multiple declarationof i. *****You will be told to write some code like (1)To find string length by using recursive function.(2)To find fibonaci series by using recursive function.(3)To write code for malloc so that allocation may be made fastly.(4)Write a fn prototype which return a pointer whichpoints to an array of 10 ints.

Technical ( C ) & Technical Subject- 60 mins, 60 questions 2. Logical Reasoning.. - 30 mins,17 questions.... ==> Questions in C were mostly from "pointers in c" and "test ur C skills" by Yeshwant Kanetkar... C questions based on command line arguments, data structure ( BST, tree traversals). All the questions were like " what is the output of the following program segment" and in many questions 3rd and 4th choices were (c) compilation error and (d) compilation, warning, runtime error.... Heard they are asking abt- ptr, string, arr, preprocessor, data structures etc.. C test was pretty ok pass by value, pass by reference etc. questions were asked The general test was pretty tough, they ask u fourier transforms,harmonics,Barkhuasen criterion,virtual memory,Whether FIFO is better than LRU etc. 4 questions were from fourier transforms the duration was 60 mins and no negative marking C basics 10 questions ,very easy.Given a program and asked the output-type questons.from pointers 3-4 questions are there. 2)reg subject:very very easy:some from digital(on nand gates. Jk flip flop),from Information theory and coding,some from Micro processors. In Logical Reasoning all the 17 questions were paragraphs (argument) of 5 to 6 sentences...five sentences (choices) will be given below and questions were asked like " which of the five if true will weaken or supports the argument above .." :- R.

INTERVIEW In the interview, they asked about Stacks, Queues, Linked lists, Binary Trees. Few questions I remember are: 1) If u have a linked list library, how do u design stack and queue using it; write pseudocode. 2) What are static variables and functions? 3) Write code in C to count the number of 1s in a character (1byte). 4) What is pre-order, post-order, in-order; write code to print post-order. 5) Can u construct a binary tree given its inorder and postorder details. Is it neccessary or sufficient to construct tree. Asked an example to do in both ways. 6) If recursion is not used to print post order, what other data structure u use (ans: Stack). 7)Can u use stack always in place of recursion? (ans: Yes) 8) What are meta characters? 9) Write a piece of code to insert a node in a linked list. 10) About malloc. 11) About Operating System - Semaphores 12) About Computability (eg:- finding infinite loop), Complexity of algorithms 13) What does compiler and assembler do? They asked grep command in Linux. How do u search '\n', using grep, in a file. They may ask some other commands if u say u r familiar and recently been using linux. About Networks? OSI reference model. what does transport layer do? TCP belongs to which layer? IP belongs to which layer? Where is error correction done? What is a connection oriented/ connection less transmission? What is meant by reliable transmission protocol? why is it called so? What is flow control and where it is done? About ur project? Asked me expalin about the project in brief. If u don't know anything, say it sincerely. U cannot bluff them. I too spoke to them sincerely. They were cool. U need not get tensed. They won't attack you. Just they want to know ur hold about the subject. Next Paper NOTE : Answer May Not be Accurate So Get An Idea of Questions.

Technical ( C ) & Technical Subject- 60 mins, 60 questions2. Logical Reasoning.. - 30 mins,17 questions....==> Questions in C were mostly from "pointers in c" and "test ur C skills" by Yeshwant Kanetkar... C questions based on command line arguments, data structure ( BST, tree traversals). All the questions were like " what is the output of the following program segment" and in many questions 3rd and 4th choices were (c) compilation error and (d) compilation, warning, runtime error.... Heard they are asking abt- ptr, string, arr, preprocessor, data structures etc.. C test was pretty ok pass by value, pass by reference etc. questions were asked The general test was pretty tough, they ask u fourier transforms,harmonics,Barkhuasen criterion,virtual memory,Whether FIFO is better than LRU etc. 4 questions were from fourier transforms the duration was 60 mins and no negative markingC basics 10 questions ,very easy.Given a program and asked the output-type questons.from pointers 3-4 questions are there. 2)reg subject:very very easy:some from digital(on nand gates.
