C Exercises: Check if a given array of integers contains a 3 or a 5

C-programming basic algorithm: Exercise-58 with Solution

Write a C program to check if a given array of integers contains a 3 or a 5.

C Code:

#include <stdio.h>
#include <stdlib.h>
// Function prototype for 'test'
int test(int nums[], int arr_size);

int main(void){
    int arr_size;

    // Declaration and initialization of an integer array 'array1'
    int array1[] = {5, 5, 5, 5, 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[] = { 1, 6, 8, 10};
    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, 3, 3, 5, 5, 5};
    arr_size = sizeof(array3)/sizeof(array3[0]);

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

// Definition of the 'test' function
int test(int nums[], int arr_size)
{
    // Looping through the elements of the array
    for (int i = 0; i < arr_size; i++)
    {
        // Checking if the current element is neither 3 nor 5
        if (nums[i] != 3 && nums[i] != 5)
        {
            return 0; // If found, return 0 (false)
        }
    }
    return 1; // If no other element is found, return 1 (true)
}

Sample Output:

1
0
1
