# C Program to compute the perimeter of triangle

## C program to find the perimeter of a triangle

This c program is used to calculate the perimeter of a triangle based on user inputs each side lengths length1, length2 and length3.

## Formula to compute perimeter of a triangle

```Perimeter of a triangle: length1 + length2 + length3

length1, length2 and length3 are length of each sides of triangle.

```

## C program to calculate the perimeter of a triangle

```// Finds perimeter of a triangle
#include<stdio.h>

void main()
{
int length1, length2, length3, perimeter=0;
printf("\nFinds perimeter of a triangle\n------------------------");
printf("\nEnter Length1: ");
scanf("%d", &length1);
printf("\nEnter Length2: ");
scanf("%d", &length2);
printf("\nEnter Length3: ");
scanf("%d", &length3);

perimeter = length1+length2+length3;

printf("Perimeter of a triangle is: %d", perimeter);
}
```

Output:

```\$ cc perimeter-of-triangle.c
\$ ./a.out

Finds perimeter of a triangle
------------------------
Enter Length1: 5

Enter Length2: 7

Enter Length3: 9
Perimeter of a triangle is: 21[
