C Practice Exercise

Write a C program to check if two numbers in a pair are in ascending order or descending order.

C Code:

#include <stdio.h>
int main() {
    int x, y, i, total = 0; // Declare variables for user input and calculations
    printf("\nInput a pair of numbers (for example 10,2 : 2,10):");
    printf("\nInput first number of the pair: ");
    scanf("%d", &x); // Read the first number
    printf("\nInput second number of the pair: ");
    scanf("%d", &y); // Read the second number

    if (x > y) {
        printf("The pair is in descending order!"); // If x is greater than y, print message for descending order
    } else {
        printf("The pair is in ascending order!"); // Otherwise, print message for ascending order
    }

    printf("\n");
    return 0;
} 

Sample Output:

Input a pair of numbers (for example 10,2 : 2,10):                                                   
Input first number of the pair: 10                                                                   
                                                                                                     
Input second number of the pair: 2                                                                   
The pair is in descending order!
