**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
