Files&Records(Entering records)

Hi!
I need help on my program.(well, I haven't started yet)
Anyone knows anything about entering records?.

E.g. I need a program that You can enter the stats for a tennis player. Then after you are done it will save it in a .txt file in a form of a table. Then If you want to view those records it will be view it in the same window(which is MS-DOS) by a player's rank. If anyone thinks that's easy, its not for me :( . (The teacher expects us to know that by our selves, and he said that we can use 'fscanf', 'fprintf', 'fopen', 'fclose', 'fputs', 'fgets', 'fputc', 'fgetc'.. Whatever those mean :S).

I need help, please. Any ideas or programs would be appreciated.
Thanks

Lookup structs and read about all those lovely IO functions.

There's plenty of examples on here if you'd only search for it ;)
