Write a C program to check a given array of integers. The program will return true if the value 5 appears 5 times and there are no 5 next to each other.

C Code:

#include <stdio.h>
#include <stdlib.h>

// Function prototype for 'test'
int test(int numbers[], int arr_size);

int main(void){
    int arr_size;

    // Declaration and initialization of an integer array 'array1'
    int array1[] = { 3, 5, 1, 5, 3, 5, 7, 5, 1, 5 };
    arr_size = sizeof(array1)/sizeof(array1[0]);

    // Printing the result of the 'test' function for 'array1'
    printf("%d",test(array1, arr_size));

    // Declaration and initialization of an integer array 'array2'
    int array2[] = {3, 5, 5, 5, 5, 5, 5};
    arr_size = sizeof(array2)/sizeof(array2[0]);

    // Printing the result of the 'test' function for 'array2'
    printf("\n%d",test(array2, arr_size));

    // Declaration and initialization of an integer array 'array3'
    int array3[] = {3, 5, 2, 5, 4, 5, 7, 5, 8, 5};
    arr_size = sizeof(array3)/sizeof(array3[0]);

    // Printing the result of the 'test' function for 'array3'
    printf("\n%d",test(array3, arr_size));

    // Declaration and initialization of an integer array 'array4'
    int array4[] = {2, 4, 5, 5, 5, 5};
    arr_size = sizeof(array4)/sizeof(array4[0]);

    // Printing the result of the 'test' function for 'array4'
    printf("\n%d",test(array4, arr_size));
}

// Definition of the 'test' function
int test(int numbers[], int arr_size)
{
    int flag = 0;
    int five = 0;

    // Looping through the elements of the array
    for (int i = 0; i < arr_size; i++)
    {
        if (numbers[i] == 5 && !flag)
        {
            five++;
            flag = 1;
        }
        else
        {
            flag = 0;
        }
    }

    // Returning true if there are exactly 5 consecutive occurrences of the number 5
    return five == 5;
}

Sample Output:

1
0
1
0

Previous: Write a C program to check a given array of integers and return true if the given array contains either 2 even or 2 odd values all next to each other.
Next: Write a C program to check a given array of integers and return true if every 5 that appears in the given array is next to another 5.
