In your opinion, what is the best method for validating a user input string.
For example , to make sure that the user input 7 digits as opposed to letters or a mix of the two.

Should I use a loop...

Thanks for the help!
The issue was indeed the linefeed in the gets() value, which was removed using the above method.

Are you referring to this?

Any suggestions?

Thanks for the tip.
So I switched to fgets()




else
{
printf("File was opened");

Hi everyone,

I'm working on a program for developing files for student marks. My issue is in the else statement. What's happening is that it prints the prompt for the First Name but then prints...
