Hello there,

Increment and decrement operators, are one of the most important operators in C language.

Both are of two types.

Prefix Increment : ++a;  Postfix Increment : a++;

Prefix Decrement : --a ; Postfix Decrement : a--;

The precedence of post I and D operators is greater than Pre I and D operators. While as the associativity of Post I and D is from left to right whereas the associativity of Prefix I and D is from right to left .

Example:

int a,b,c ;

a = 10, b= 20, c = 1 ;

c += a++ * 5 - --b;
Output : 32

Hope it helps.
