sprintf - String width/precision using wildcard

sprintf - String width/precision using wildcard

sprintf - String width/precision using wildcard

You know how you can write:


$result = sprintf("%*s\n",9,"HELLO");
Is it possible to use %*.*s using the same argument value...without having a separate argument?

For example, the "proper" way would be:


$result = sprintf("%*.*s\n",9,9,"HELLO");
But, I want to do something like this...and have it work correctly:


$result = sprintf("%*.*s\n",9,"HELLO");
Is there a way to do something like this?

Thanks in advance!

RE: sprintf - String width/precision using wildcard

None of that makes any sense.

$result is an invalid variable name in C.  Variables (and functions) can only use letters, numbers or underscores.

The first parameter of sprintf() must be a char* string variable, not a literal string constant.

What exactly are you trying to do?

Sorry, I'm mixing my languages.

I figured out a work-around, so we can close this thread.

Thanks for your response!
