i am new to C programming but i am learning. i am trying to make a program that will format a drive but i don't know what code i would use to execute the format command.

here is the code:

#include "stdio.h"

int main(void){
char drive;
char x;
printf("Enter Drive letter:\n");
scanf("%c", &drive);
printf("Drive %c will now be formatted!\n", drive);
(format command goes here)
return 0;
}

what do i use to format the drive please help!!!

A useful function for this is system(). The argument that this function takes is the command that you want executed, whatever you insert in the parentheses will be executed as if it is in a terminal/bash. For example:

int main(void) {

system("clear");
return 0;

}

will clear the screen anytime it is ran. So maybe something like:

#include "stdio.h"

int main(void){
char drive;
char x;
printf("Enter Drive letter:\n");
scanf("%c", &drive);
printf("Drive %c will now be formatted!\n", drive);
system("<command to format drive here>");
return 0;

}

first, dont necropost, second, dont help morons on this site with trivial shit, they usually have bad intentions, like formatting their school computers......

Plus, that won't work. You can't format a partition that you're using. Best you can hope to do is delete a bunch of shit and make the OS unstable.

And my God, you're using C.... why even try to make the call to system? There should be a fancier way of doing that.

ok first of all im not trying to use it for a virus, i mean i know this is in hacking but its also under programming, i don't plan on formatting an active hard drive i know that doesn't work, i am making a program that sets up a usb drive for something, this includes formatting it and then copying the files to it. but whatever i'll try it

lol you need to start with WAY WAY easier things than that...

...whut are you talking about?

as to the question: if you want to set up a usb drive, what do you need to format it for? are you trying to make it bootable? are you trying to move--you know what, tell me the details of what you're trying to do, and ill try to help, asking random questions that come to mind isnt really gonna be of much help

ok, i am trying to make a program that creates magic memory sticks for softmodding the psp, it was just out of being bored, cause i can easily make one with a command prompt, i just though it would be interesting to make a c program do it, and im still teaching myself c so i don't know everything about it

i thought there were programs that did that already.....as to doing it in c, if you're gonna use system, you might as well just use a batch file, it'll be doing the same job, only you wont need to compile every time you change something....and it'll be a little easier to edit....but if you really want to do it in c, just make a batch file that does it, and for every line in the batch file, make a system call in your c programme's source containing the line.....if you dont want to do that, look into formatting drives in c online, google will be a better resource than asking on a forum, in this case

i know i could use a batch file, thats what i did anyways, but i wanted to take it a step further and do it in c, and i searched google but didn't find much
