Reading lines from a file and saving to a variable

hi is there any one who would be kind enough to tell me the function or even an example :P
on how to read lines and and so on from a file and save to a char say like

##1234
##4321
##abcd

and it reads say 3 from the first line.
1 from the second line and a from the first line
thanks :)

FAQ. Replace stdin with the file pointer for your file. Look up the functions fopen and fclose for opening and closing files.
