C-programming basic algorithm: Exercise-75 with Solution

Write a C program to check a given array (length will be atleast 2) of integers and return true if there are two values 15, 15 next to each other.

C Code:

#include <stdio.h>
#include <stdlib.h>
int main(void){
int arr_size;
int array1[] = {5, 5, 1, 15, 15};
arr_size = sizeof(array1)/sizeof(array1);
printf("%d",test(array1, arr_size));
int array2[] = {15, 2, 3, 4, 15};
arr_size = sizeof(array2)/sizeof(array2);
printf("\n%d",test(array2, arr_size));
int array3[] = {3, 3, 15, 15, 5, 5};
arr_size = sizeof(array3)/sizeof(array3);
printf("\n%d",test(array3, arr_size));
}
int test(int nums[], int arr_size)
{
for (int i = 0; i < arr_size - 1; i++)
{
if (nums[i + 1] == nums[i] && nums[i] == 15) return 1;
}
return 0;
}

Sample Output:

1
0
1
