C Exercises: Compute the sum of the two specified integers. If one of the given integer value is in the range 10..20 inclusive return 18
C-programming basic algorithm: Exercise-22 with Solution
Write a C program to compute the sum of the two given integers. If one of the given integer value is in the range 10..20 inclusive return 18.
C Code:
#include <stdio.h>
#include <stdlib.h>
int main(void){
printf("%d",test(3, 7));
printf("\n%d",test(10, 11));
printf("\n%d",test(10, 20));
printf("\n%d",test(21, 220));
}
int test(int x, int y)
{
return (x >= 10 && x <= 20) || (y >= 10 && y <= 20) ? 18 : x + y;
}
Sample Output:
10 18 18 241

C Programming: Tips of the Day
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().
