incrementing variables in C++
Hello,

what is the result of the below, and how does it work?

Code:
int i = 5;
cout << i++ * ++i << endl;
cout << i << endl;

Compile it and find out. Because this looks like a homework assignment.

int i = 5;
cout << i++ * ++i << endl;
cout << i << endl;

The integer is 5.

++ is an increment to the integer and then adds 1 to the variable if it precedes the variable. If it follows the value of the variable returns the value before it was incremented.

Most likely the value of that is 30 (5*6) but yeah, learn to compile Smilie

If this is not a homework, can we know the intention behind this question?
