question about c.

Well I run bots on my computer all day when I'm not at home and the new one crashes quite a bit. I was wanting to make a program that would just restart it for me everytime it turns off. This is my script:

#include <stdio.h>
FILE *fp;

int main(void)
{
fp = fopen("mephbot.exe", "???");

if(fclose(fp))
{
fp = fopen("mephbot.exe", "???");
}

return 0;
}


I was thinking that would do it but it does absolutely nothing...doesn't even start my program. Mephbot.exe is the name of the program I did check that and where I put the question marks I have tried many differen combos. Any help as to why this is not working would be helpful...thnx
