Increment and decrement operators in C++ with examples - Techilm

Increment operator (++)

The increment operator (++) increases the value of a variable by 1. It is mostly used inside a loop to increment the loop counter. Syntax of increment operator is below:

int number = 0;

number++;

number++ will increase the value of a variable number by 1.

Decrement operator (--)

The decrement operator (--) decreases the value of the variable by 1. It is also used in the loop when we need to decrement loop counter by 1 in each loop iteration. Syntax of decrement operator is below:

int number = 1;

number--;

number-- will decrease the value of a variable number by 1.

Both operators are unary operators as both work on only one operand.
