How do I read a file in C?

To read a file in C, you can use the fopen, fgets, and fclose functions. Would you like a code example?

Yes, please provide a code example.

Here's a simple example:

#include <stdio.h>

int main() {
    FILE *file;
    char line[256];

    file = fopen("example.txt", "r");
    if (file == NULL) {
        perror("Error opening file");
        return 1;
    }

    while (fgets(line, sizeof(line), file)) {
        printf("%s", line);
    }

    fclose(file);
    return 0;
}

What if the file doesn't exist?

You should check if the file pointer is NULL after calling fopen. If it is, you can handle the error appropriately, like in the example.
