C
program for area of a triangle
Formula of
area of any triangle:
Area = √(s*(s-a)*(s-b)*(s-c))
Where s = (a + b + c)/2
C code:
#include<stdio.h>
#include<math.h>
int main(){
float a,b,c;
float s,area;
printf("Enter
size of each sides of triangle");
scanf("%f%f%f",&a,&b,&c);
s
= (a+b+c)/2;
area
= sqrt(s*(s-a)*(s-b)*(s-c));
printf("Area of
triangle is: %.3f",area);
return 0;
}
Sample
output:
Enter size of each sides of the triangle: 2 4 5
Area of triangle is: 3.800
7. Write a c program to find the area of rhombus.
8. Write a c program to find the area of parallelogram.

this answer is wonderful really i like you
when i put 2 4 6 shows wrong answer
i.e., when s= even
thats not a valid tringle.....for a valid tringle {if(a+b>c && b+c>a && c+a>b)}
I missed a thing i.e your a(2)+b(4)is not greater then c(6)
thanks
Who made this program in this website thank you very much. May god give you power and arrange to you all the situation to help the other like this.
Thanx for the help
Thanks for the help...but what if write float a,b,c,s,area; instead of
float a,b,c;
float s,area;
Write a C program to print the following triangle:
thnks man this makes programing c easy
why you write in last printf 3f
please help me. i want to write a program in C. that gets 3 sides and gives 3 angles. pleaseeeeee
this is my mail.. please heeeeeelp me. leylakalhor@rocketmail.com
Why you write %.3f
three digits after decimal point.
Example : 3.800
If it was %.5f
It would have been - 3.80000
I feel really happy to have seen your webpage and look forward to so many more entertaining times reading here. Thanks once more for all the details.
