"without repeating the first character in reading ", that depends on what on earth you are talking about.

This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work from. And without your input file we can't have any idea what you are getting as output! So edit your question, show us a few lines of sample input data, and add sample output - explaining exactly what you didn't expect to get!
Use the "Improve question" widget to edit your question and provide better information.

Oh, and BTW: pick a bracketing style and STICK TO IT.
Changing from K&R to "hide the brackets and don't indent the code" doesn't make even trivial code samples like that easy to read.

Solution 1

I think your fscanf() statement should be without [i]:

fscanf(in,"%s %d %lf",&course_name,&number_of_student,&courses_average_grade);

Solution 2

course_name and &course_name[i] are the same only if i is zero!!!
So write in fscanf also course_name only...
