      #include <stdio.h>
      int getc( FILE *stream );
The getc() function returns the next character from stream, or EOF if the end of file is reached. getc() is identical to fgetc(). For example:
       char ch;
       FILE *input = fopen( "stuff", "r" );

       ch = getc( input );
       while( ch != EOF ) {
         printf( "%c", ch );
         ch = getc( input );
       }
