C++ Exercises: Check three given integers and return true if one of them is 20 or more less than one of the others

C++ Basic Algorithm: Exercise-48 with Solution

20 Less Than Another Integer

Write a C++ program to check three given integers and return true if one of them is 20 lower than one of the others.

Sample Solution:

C++ Code :

#include <iostream>
using namespace std;

// Function 'test' takes three integers (x, y, z) as parameters
bool test(int x, int y, int z)
{
    // Returns true if the absolute difference between any two numbers among x, y, and z is greater than or equal to 20
    return abs(x - y) >= 20 || abs(x - z) >= 20 || abs(y - z) >= 20;
}

int main() 
{
    // Testing the 'test' function with different sets of numbers
    cout << test(11, 21, 31) << endl;  // Output: 1 (True, as differences between any two numbers are greater than or equal to 20)
    cout << test(11, 22, 31) << endl;  // Output: 1 (True, as differences between any two numbers are greater than or equal to 20)
    cout << test(10, 20, 15) << endl;  // Output: 0 (False, as no pair of numbers have differences greater than or equal to 20)

    return 0;    
}

Sample Output:

1 
1 
0

Previous: Write a C++ program to check if two or more non-negative given integers have the same rightmost digit.
Next: Write a C++ program to find the larger from two given integers. However if the two integers have the same remainder when divided by 7, then the return the smaller integer. If the two integers are the same, return 0.
