Thread: How do I write to a file without hitting enter? (windows)

Code:

while ((ch = _getch()) != 'y' && i < lim - 1)
{
    str[i++] = (char)ch;
}

str[i] = '\0';

This allows sufficient room for the typed characters, plus the terminating '\0', and excludes your stop character from the string. Personally, I'd favor using EOF instead of a potentially valid character to stop input, because at present you cannot write 'y' to your file in any meaningful way.

This snippet isn't very robust, but I didn't want to complicate things for you just yet.

The code I want checked is this (see first post)

Code:

int ch;
...
 while (ch != 'y'){
    ch = _getch();
    fprintf(fp, ch);
}

replace the str array to textfile
