bookCompound Assignment Operator

A compound assignment operator is a combined operator that combines an assignment operator and an arithmetic (or a bitwise) operator. The result of such an operation is assigned to the left operand (what is before the = sign).

cpp

main

copy

              
12345678910

            
#include <iostream>

int main()
{
	int some_variable = 0;
	std::cout << "Old value of the variable: " << some_variable << std::endl;

	some_variable += 500; // using a compound assignment operator
	std::cout << "New value of the variable: " << some_variable << std::endl;
}

Using another compound assignment operator:

cpp

main

copy

              
123456789101112131415161718192021

            
#include <iostream>

int main()
{
	int value = 0;
	
	value += 20; // value = value + 20
	std::cout << "value = 0 + 20 =  " << value << std::endl;

	value -= 4; // value = value - 4 
	std::cout << "value = 20 - 4 =  " << value << std::endl;

	value *= 4; // value = value * 4
	std::cout << "value = 16 * 4 = " << value << std::endl;
	
	value /= 8; // value = value / 8
	std::cout << "value = 64 / 8 = " << value << std::endl;

	value %= 5; // value = value % 5
	std::cout << "value = 8 % 5 = " << value << std::endl;
}

Everything was clear?

How can we improve it?

Thanks for your feedback!
