Final Answer

Increment and decrement operators are unaryoperators that add or subtract one from their operand, respectively. They are commonly implemented inimperativeprogramming languagesC-like languages became notorious for featuring two versions (pre- and post-) of each operator with slightly different semantics.


int  x;
int  y;
// Increment operators
x = 1;
y = ++x;    // x is now 2, y is also 2
y = x++;    // x is now 3, y is 2
// Decrement operators
x = 3;
y = x--;    // x is now 2, y is 3
y = --x;    // x is now 1, y is also 1
