C++/Hello, Rai on io input..
Just as there is a way to get the next character value from a file
last week i've seen that there was a way to go back a character.
please, can you help me out?
Please read the man pages for
int fputc(int c, FILE *stream);
int fputs(const char *s, FILE *stream);
int putc(int c, FILE *stream);
int putchar(int c);
int puts(const char *s);
int ungetc(int c, FILE *stream);
I guess that you are involved in some kind of parsing activity. If you need any information, please let me know.
