C File Handling

File handling in C allows you to perform operations like reading, writing, and opening files.

Opening a File

#include 

int main() {
    FILE *file;
    file = fopen("example.txt", "w");

    if (file == NULL) {
        printf("Error opening file.\n");
        return 1;
    }

    fprintf(file, "Hello, file!\n");
    fclose(file);
    return 0;
}

This program demonstrates how to open a file for writing, write to it, and close it.
