Prefix 

count = ++tick;  increase variable tick by 1, then copies the value of tick to count 
count = tick;  decrease variable tick by 1, then copies the value of tick to count 
Postfix 

count = tick++;  copies the value of variable tick to count then increase tick by 1 
count = tick;  copies the value of variable tick to count then decrease tick by 1 
int count =0, tick =0;
count= ++tick; //tick = 1 count = 1
count= tick; //tick = 0 count = 0
count= tick++; //tick = 1 count = 0
count= tick; //tick = 0 count = 1
You can also do the following;
count += total; //is same as count=count + total;
count = total; // is count=count – total;
count *=3; // is count=count * 3;
Confused? Anyone doesn’t understand, keep your hand on your mouse and post comments. :)
