  At times we need to use ++a. 

  int a = 1;
  int b;
  int c;
  
  1.  b = a++;
  2.  c = ++a;
  

  In the first statement, the value of b is 1. First, b = a, then there is an increament in the value of a, so a becomes 2.

  On the other hand, the value of c becomes 2 becuse first c is taking the increased value of a. Also, a becomes 2 in both of the cases.

  Hope you have understood the difference now. Feel free to comment down any further doubts.
