82. Compare Two Numbers

Write a program in C++ to compare two numbers.

Sample Solution:-

C++ Code :

#include <iostream> // Including the input-output stream library
using namespace std; // Using standard namespace

int main() // Main function
{
    int num1, num2; // Declare two integer variables num1 and num2

    // Displaying a message for the comparison of two numbers
    cout << "\n\n Compare the first number with second number numbers:\n";
    cout << "---------------------------------------------------------\n";

    // Asking user to input the first integer
    cout << " Input the first integer: ";
    cin >> num1; // Taking user input for num1

    // Asking user to input the second integer
    cout << " Input the second integer: ";
    cin >> num2; // Taking user input for num2

    // Comparing and displaying if num1 is equal to num2
    if (num1 == num2)
        cout << num1 << " == " << num2 << endl;

    // Comparing and displaying if num1 is not equal to num2
    if (num1 != num2)
        cout << num1 << " != " << num2 << endl;

    // Comparing and displaying if num1 is less than num2
    if (num1 < num2)
        cout << num1 << " < " << num2 << endl;

    // Comparing and displaying if num1 is greater than num2
    if (num1 > num2)
        cout << num1 << " > " << num2 << endl;

    // Comparing and displaying if num1 is less than or equal to num2
    if (num1 <= num2)
        cout << num1 << " <= " << num2 << endl;

    // Comparing and displaying if num1 is greater than or equal to num2
    if (num1 >= num2)
        cout << num1 << " >= " << num2 << endl;
}

Sample Output:

 Compare the first number with second number numbers:                  
---------------------------------------------------------              
 Input the first integer: 25                                           
 Input the second integer: 15                                          
25 != 15                                                               
25 > 15                                                                
25 >= 15
