Question

Create a basic program (C programming language) that accomplishes the following requirements:

1. Allows the user to input 2 numbers, a starting number x and ending number y
2. Implements a while loop that counts from x (start) to y(end).

• Inside the loop, print to the screen the current number
• Print rather the current number is even or odd
• If the number is even , multiply by the number by 3 and print the results to the screen.
• If the number is odd , add 10 and print the results to the screen.
• Use at least 1 increment or decrement operator.

Answer 1

Program:

#include <stdio.h>

int main()
{
    int x, y;
    printf("Enter 2 numbers:\n");
    // Takes input of starting number from user
    printf("Enter starting number : ");
    scanf("%d",&x);
    // Takes input of ending from user
    printf("Enter ending number : ");
    scanf("%d",&y);
    
    // Loop iterates till the x is less than or equal to y
    while (x <= y) {
        // Printing the current number
        printf("Current number is: %d\n", x);
        // Condition to check if x is even
        if (x%2 == 0) {
            // Printing the current number is even
            printf("The current number is even\n");
            // Multiplying the number with 3 and print the result
            printf("%d\n", x*3);
        } else { // If x is odd
            // Printing the current number is odd
            printf("The current number is odd\n");
            // Adding 10 to the number and print the result
            printf("%d\n", x+10);
        }
        // Incrementing the x value
        x++;
    }
    
    return 0;
}

Output:
