I don't quite understand what help do you need. tolower() is a standard function from <ctype.h> header. If you want to apply it to an arbitrary string you could do something like:
Code:void lower_string(char *str) { while (*str) { *str = tolower(*str); ++str; } }

Thank you dear GL.Sam. You re right . I must write example code.
In my menu
at
case 1 : tolower ()
case 2 : delete_line()
"delete_line()" function is written by me and working perfect at "case 2" . But i want to call "tolower()" function at "case 1" for all words to lowercase in file (for example ; simple.txt) .Code:case 1 : tolower();/* at these , i want to all words lowercase in a file*/ break ; case 2 : delete_line() ; /* delete line*/ break ;
How can i succes this ? Thank you .
