The subtraction operator (-) subtracts the value of the right operand from the value of the left operand and returns the difference. It is supported for all built-in numeric data types, including integers and floating-point values.

When both operands are integers, the result is an integer. If one or both operands are floating-point values, the operands undergo the usual arithmetic conversions, and the result is a floating-point value.

Source Code #

#include <iostream>

int main()
{
    int num1 = 50;
    int num2 = 18;

    int difference = num1 - num2;

    std::cout << "First Number : " << num1 << '\n';
    std::cout << "Second Number: " << num2 << '\n';
    std::cout << "Difference   : " << difference << '\n';

    return 0;
}

Output #

First Number : 50
Second Number: 18
Difference   : 32

Explanation #

• The subtraction operator (-) subtracts the value of the right operand from the value of the left operand.
• num1 - num2 evaluates to the difference between the two integer values.
• The resulting value is assigned to the variable difference.
• Both operands are of type int, so the result is also an integer.
• The value stored in difference is displayed using std::cout.
• The subtraction operator can also be used with floating-point data types.
• return 0; terminates the program successfully.
