    how to add variables to the system command

    is there any way to do it.Like say I wanted to create a directory with the same name as the vaiable x.I've tried system("mkdir %s",x) but it didn't work.

    Use the sprintf() command to put your variables into a string, then pass that string.

    The declaration of system is
    int system(const char *string)

    So it would stand to reason that you might be able to do something like this:
    char s1[20] = "MKDIR";
    char s2[20] = '\0';
    scanf( "%s", s2 );
    strcat( s1, s2 );
    system( s1 );
    pointer = NULL
