Increment and decrement operators

In C#, there are two operators used for increasing or decreasing the value of a variable by 1. The increment operator is denoted by "++" and the decrement operator is denoted by "--".

For example, consider the following code:

int num;
num=10;
num++;

After the last statement, the value of `num' is 11. Similarly,

int num;
num=10;
num--;

The last statement will decrease the value of `num' by 1 and make it 9.
