C Exercises: Check a given array of integers and return true if there are two values 15, 15 next to each other

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[0]);
    printf("%d",test(array1, arr_size));
    int array2[] = {15, 2, 3, 4, 15};
    arr_size = sizeof(array2)/sizeof(array2[0]);
    printf("\n%d",test(array2, arr_size));
    int array3[] = {3, 3, 15, 15, 5, 5};
    arr_size = sizeof(array3)/sizeof(array3[0]);
    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
