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.

Output:

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