I have written three programs,ls,ls-a,ls-l.and executing the programs by using command line arguments in ls program.instead of that i want to run three programs in one program instead of having three separate files. please help me in this. the code i have used is:

if (argv[1] != NULL) {
    if (!strcmp(argv[1], "-a")) {  
        system("./lsa");
        exit(0);}

   if (!strcmp(argv[1], "-l")) {
        system("./code");                                    
         exit(0);
    }
}

./lsa and ./code are my .exe files.

thank you.
