Read alphanumeric data from a file and convert it in to text

Hi,
It's hard to say just what you are looking for here, but I'll take a guess and just assume you need to read a line from a file and display it.
First, open the file in text mode for reading...
(use fread( ) for binary mode)
FILE *fp;
char line[81];
fp = fopen("filname", "r"
; /*need to do some error checking*/
...Then read a line with fgets and display it.
if( fgets( line, 80, fp ) == NULL)
fprintf(stderr, "fgets error\n" );
else
fprintf(stdout, "%s", line);
You can add a while loop until the EOF and do processing on each line. fgets( ) reads in one line up to and including the newline character or up to the number of chars specified (in this case, 80) - whichever comes first.
That will give you a start.
