C Exercises: Find the third angle of a triangle if two are given
C Input Output statement: Exercise-10 with Solution
Write a C program to find the third angle of a triangle if two angles are given.
Pictorial Presentation:
Sample Solution:
C Code:
#include <stdio.h>
int main()
{
int ang1, ang2, ang3; /*are three angles of a triangle */
/* Read two angles of the triangle from user separated by comma*/
printf("Input two angles of triangle separated by comma : ");
scanf("%d, %d", &ang1, &ang2);
ang3 = 180 - (ang1 + ang2); /* Calculates the third angle */
printf("Third angle of the triangle : %d\n", ang3);
return 0;
}
Sample Output:
Input two angles of triangle separated by comma : 50,70 Third angle of the triangle : 60

Static variable inside of a function in C
The scope of variable is where the variable name can be seen. Here, x is visible only inside function foo().
The lifetime of a variable is the period over which it exists. If x were defined without the keyword static, the lifetime would be from the entry into foo() to the return from foo(); so it would be re-initialized to 5 on every call.
The keyword static acts to extend the lifetime of a variable to the lifetime of the programme; e.g. initialization occurs once and once only and then the variable retains its value - whatever it has come to be - over all future calls to foo().
