Reading a text file up to a certain character

Question

Here's my dilemma. I have a file, and wish to read in all characters up until the program hits a '#', and ignore everything on that line after the '#'. For example

0 4001232 0 #comment, discard

This is frustrating, as it feels like there is a very simple solution. Thanks!

Answer 1

FILE *f = fopen("file.txt", "r");
int c;
while ((c = getc(f)) != '#' && c != EOF)
   putchar(c);
