No, you have to use the sprintf (better use snprintf) approach. "some static text"+3 just increases the address returned by the string literal by 3 bytes, which would actually pass "e static text" to your function.

Betreff: Re: [C400-L] basic c question about char *
Thank you for all the reply. Now I've a better understanding of char *.
One more question:
Void myFunction(char *message)
myFunction("my static message");
// above function call is pretty straight forward. But what if I need
to pass non static message to it? Is there a way to do it without
having to create a char * or char [] variable. Something like this (I
know the syntax is not correct):
myFunction("my static message" + myInt);
Or do I have to do
char myMessage[20];
sprintf(myMessage, "my non Static message %i", myInt);
myFunction(myMessage);

Subject: [C400-L] basic c question about char *
can somebody help me understand how char * work?
char * s1;
s1 = "assign a value";
s1 = "assign another value"; //does c auto deallocate storage and
reallocate a longer one for this assignment?
. . .
char * s1
int myInt = 10;
sprintf(s1, "test %i", myInt); //why is s1 contains *null after this
assignment?
