Question 01

Write a C program that asks the user for an integer value, and outputs whether or not this integer is a multiple of 2, 3, 4, 5, 6, 7, 8, or 9.

Answer 01

There are many ways to solve this problem, and this is one of them.

    #include <stdio.h>
    
    void main() 
    {
        int num;
        int isMultiple = 0; // Flag to track if any multiples are found
    
        // Ask the user for an integer value
        printf("Enter an integer: ");
        scanf("%d", &num);
    
        // Check for multiples from 2 to 9
        for (int i = 2; i <= 9; i++) 
        {
            if (num % i == 0) 
            {
                printf("%d is a multiple of %d\n", num, i);
                isMultiple = 1; // Set flag if a multiple is found
            }
        }
    
        // If no multiples were found, print a single message
        if (!isMultiple) 
        {
            printf("%d is not a multiple of any number from 2 to 9\n", num);
        }
    }
