How to use execv() without warnings?

Question

I am working on MacOS-X Lion with GCC 4.2. This code works, but I get a warning I would like fix:

#include 
main()
{
    char *args[] = {\"/b         


        

Answer 1

Change:

char *args[] = {"/bin/ls", "-r", "-t", "-l", (char *) 0 };

To:

char *const args[] = {"/bin/ls", "-r", "-t", "-l", NULL };
