💼File management

For accessing files, we shall use FILE structure in the following way,

#include <stdio.h>

int main()
{
    FILE* fp;
    fp = fopen("file.txt", "w");
    fclose(fp);
    return 0;
}

Here, fopen("file_path", "mode");

for modes,

a = append (creates file if not present)
w = write (creates file if not present)
a = read (error if not present)

---

Here, fclose(fp) is optional!
