pre increment vs post increment c++ Code Example
pre-increment vs post-increment 
++x (pre-increment) means "increment the variable; the value of the expression is the final value"
x++ (post-increment) means "remember the original value, then increment the variable; the value of the expression is the original value"

pre increment vs post increment c++ 
b = x++;
// In this example suppose the value of variable ‘x’ is 5 then value of variable ‘b’ will be 5 because old value of ‘x’ is used.

b = ++y;
// In this example suppose the value of variable ‘y’ is 5 then value of variable ‘b’ will be 6 because the value of ‘y’ gets modified before using it in a expression.
