Maybe it will you do define the difference between ++i and i++;

The statements do the same with one difference:
The value of the statement "++i" is i+1
while the value of i++ is i:

#include <iostream>
using namespace std;

int main()
{
int i=6;
cout << "i++: " << i++ << endl; //Will return i = 6
int j=6;
cout << "++i: " << ++i << endl; //Will return i+1 = 7
return 0;
}

I hope this will you!
