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:

Code:

---

char s1[20] = "MKDIR";
char s2[20] = '\0';

scanf( "%s", s2 );
strcat( s1, s2 );
system( s1 );
