C
program for area of circle
#include <stdio.h>
#define PI 3.141
int main(){
float r, a;
printf("Radius: ");
scanf("%f", &r);
a = PI * r * r;
printf("%f\n", a);
return 0;
}
Mathematical
formula for area of circle:
Here
Pie is constant which is equal to
Pie = 22/7 or
3.14159265358979323846264338327950288419716939937510...
Radius
is radius of the circle.
7. Write a c program to find the area of rhombus.
8. Write a c program to find the area of parallelogram.

This program is easy to understand..
There are a few things wrong with this.
First, it's spelled "pi"
Second, 22/7 is not equal to "pi"
when the %f\n derived
why use %f\n instead of %f
\n is used to print after some space... aksh
some escape sequences unnecessary
\n for space
I planing to write algorithm part of my project work question is following
problem is finding intersection of between two ellipses
(x-x1)^2/a^2+(y-y1)^2/b^2=1,(x-x2)^2/c^2+(y-y2)^2/d^2=1 (x1,y1),(x2,y2) point of ellipse and a,b,c,d are major and minor axis of ellipses
please provide any idea of how to find out intersection of two ellipses
"/n" is used to print in new line
\n is used to going to next line
for example:printf("hello\n world");
output is:hello
world
