problem in checking status process PID in c.

Question

I wrote a small program in C.

 

But when i compile it on my pc it goes to " loop" and my pc crashed.

 

program :

 

#include <stdlib.h>

int main()

{

label:;

system("start sleep.exe ");

goto label;

return 0;

}

Solution required:

1) Check sleep.exe is runing or not in process task list of win7.

2)if not running then run sleep.exe.

3)else goto label: for further checking.

program may be something like this:

#include <stdlib.h>

int main()

{

label:;

IF process sleep.exe is runing then{goto label:}

system("start sleep.exe ");

goto label;

return 0;

}
