Using the ++ Operator


The ++ operator can be used in prefix and postfix. When it is used as a preifx , its value is evaluated first, then the statement is executed. For example:
 
int i=1;
cout<<++i; //output will be 2
but if we use
cout<<i++; // the result will be 1
but in the very next line of the code it will be 2
similarly ,
int i=1;
i = ++i + ++i;
cout<<i;// the output will be 6 not4 or 5
