C strings

[Jspeake]

Im working on hardware interfacing with C and atm using an LCD screen to debug it. The LCD code takes a string and prints it to the LCD. My question is how can I make the string take values in the manner of printf statements?

EG:

int n;
char *str;
n=5;

Id like to do something along the lines of

str=(" this is a string and a number %d, n");

More to the point Im not sure how to save a string with a variable in it.

Thanks for the help.

sprintf() perhaps! check it out here

great that works thanks! Do you know how I could created a function that takes an arbitrary amount of strings? So I could use sprtintf to convert all needed variables then write a function say lprintf(str1, str2, etc) that would concatenate them all with white space. I think i know how to write the function but I dont know if its possible to do it for an arbitrary amount of inputs. Thanks again

Do you mean a function whose argument list changes? If that's the case then check out the one here.
