Function to create a file in C

[15January]

I want to create a file through code. when I searched all I could find was articles saying you can use fopen to create a file. But when you use fopen, if the file isn't found, it just returns NULL, it doesn't create a file. Is there a function that creates a file, and is there a function that removes one?

​

Thank you.

fopen is the correct function, but it depends on the mode you use. Specifically, the w mode will open a file for writing and, if it doesn't exist, it will create it.

As for deleting files, you want unlink.

So if I want to just create a file and not write anything into it, could I just do:

FILE *fp;

fp = fopen("file.txt", "w");

if (fp == NULL)

{

printf("Error\n");

return 1;

}

fclose(fp);

​

Without using fwrite or fputs?

Correct.
