C Exercises: Accepts 4 integers and check various condition

C Basic Declarations and Expressions: Exercise-19 with Solution

Validate four integers based on conditions

Write a C program that accepts 4 integers p, q, r, s from the user where q, r and s are positive and p is even. If q is greater than r and s is greater than p and if the sum of r and s is greater than the sum of p and q print "Correct values", otherwise print "Wrong values".

Test Data :
Input the second integer: 35
Input the third integer: 15
Input the fourth integer: 46
Expected Output:
Wrong values

C Code:

#include <stdio.h>
int main() {
    int p, q, r, s; // Declare variables for four integers
    
    // Prompt user for the first integer and store in 'p'
    printf("\nInput the first integer: "); 
    scanf("%d", &p);
    
    // Prompt user for the second integer and store in 'q'
    printf("\nInput the second integer: ");
    scanf("%d", &q);
    
    // Prompt user for the third integer and store in 'r'
    printf("\nInput the third integer: ");
    scanf("%d", &r);
    
    // Prompt user for the fourth integer and store in 's'
    printf("\nInput the fourth integer: ");
    scanf("%d", &s);

    // Check conditions for correctness
    if((q > r) && (s > p) && ((r+s) > (p+q)) && (r > 0) && (s > 0) && (p%2 == 0))
    {
        printf("\nCorrect values\n");
    } 
    else {
        printf("\nWrong values\n");
    }
    
    return 0;
}

Sample Output:

Input the first integer: 25                                            
                                                                       
Input the second integer: 35                                           
                                                                       
Input the third integer: 15                                            
                                                                       
Input the fourth integer: 46
