Question about for loop

[dkg123]

Taking an upper level c++ course in school but has been a while since I've played with it. Having trouble getting the "Student" counter to increment correctly. The section in question is immediately after the first if statement "if (i==0)". It will display "Student 1" initially, but doesn't count after that.

I have tried a couple different things but,
I would like it to display "Student 1" then "Student 2" then "Student 3"

Assistance would be great. Thanks!

// set all letters in first name to lower case, and then set first letter to upper case
for (int x = 0; x < fName.length(); x++)

// set original studentName variable to proper case formatting

// print student record

}

return 0;

PLEASE learn to use code tags, they make reading and commenting on source code MUCH easier.

HINT: you can edit your post and add code tags.

With that said, reverse these two lines:

if (i== 0){
cout << "Student " << + i+1 <<endl;

Got it going.

Thanks again.
