C Exercises: Check whether a given array of integers of length 2, contains 15 or 20
C-programming basic algorithm: Exercise-41 with Solution
Write a C program to check whether a given array of integers of length 2, contains 15 or 20.
C Code:
#include <stdio.h>
#include <stdlib.h>
int main(void){
int arr_size;
int array1[] = {12, 20};
printf("%d",test(array1));
int array2[] = {14, 15};
printf("\n%d",test(array2));
int array3[] = {11, 21};
printf("\n%d",test(array3));
}
int test(int nums[])
{
return nums[0] == 12 || nums[0] == 15 || nums[1] == 12 || nums[1] == 15;
}
Sample Output:
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().
