Hi,
I want to read in a file line by line, without knowing the line length before. Here's what I got so far:
int ch = getc(file);
int length = 0;
char buffer[4095];
while (ch != '\n' && ch != EOF) {
ch = getc(file);
buffer[length] = ch;
length++;
}
printf("Line length: %d characters.", length);
I can now figure out the line length, but only for lines that are shorter than 4095 characters. Is there a better way to do this (I already used fgets() but got told it wasn't the best way)?
