Simple Delete File Program in ANSI C for Windows

问题

Looking for a simple program to a delete a file written in ANSI C.
Just as an example how would you delete a file at "C:\test.txt" with C?

回答1:

You can delete a file from the OS using the remove() function. Like so:

#include <stdio.h>
int main(){
    if(remove("HELLO.txt") == -1)
        perror("Error in deleting a file");
    return 0;
}

The remove() function is defined in stdio.h. Here are some docs.

回答2:

Use the remove function. I believe it is in "stdio.h"

回答3:

remove or unlink

remove is declared in 'stdio.h'

unlink is declared in 'unistd.h'

unlink is posix function, remove is ansi C function. They all work fine in windows.

unlink only delete files, remove can be used to delete directories.
