C Exercises: Test whether a non-negative number is a multiple of 13 or it is one more than a multiple of 13
C-programming basic algorithm: Exercise-19 with Solution
Write a C program to test whether a non-negative number is a multiple of 13 or it is one more than a multiple of 13.
C Code:
#include <stdio.h>
#include <stdlib.h>
int main(void){
printf("%d",test(13));
printf("\n%d",test(14));
printf("\n%d",test(27));
printf("\n%d",test(41));
}
int test(int n)
{
return n % 13 == 0 || n % 13 == 1;
}
Sample Output:
1 1 1 0

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().
