C++ provides us with the assignment operators which help to shorten the code and make it more readable. They can assign the value and perform the operation at the same time.

The same syntax can be applied to all operators:

x += 2; // is equivalent to  x = x + 2
x -= 3; // is equivalent to  x = x - 3
x *= 4; // is equivalent to  x = x * 4
x /= 2; // is equivalent to  x = x / 2
x %= 5; // is equivalent to  x = x % 5

The increment operator `++` and decrement operator `--`  increases and decreases the value of the variable by 1 respectively:

int x = 2;
int y = 2;
cout << ++x << endl;
cout << --y;

The operator `++`  has two forms: prefix (++x) and postfix (x++). 
- **Prefix** increments/decrements firstly the value and then evaluates the expression. 
- **Postfix** evaluates firstly the expression and then increments/decrements the value. 

Example:

int x = 2;
int y = 2;
cout << "x: " << x++ << endl; // Firstly print the value and then increase it by 1
cout << "y: " << ++y << endl; // Firstly increase the value by 1 and then print it
