Does a function like this currently exist?

i'm wondering if a function exists that basically appends a string in a formatted style. example:

Code:

---

int x = 50;
int y = 100;
char *blah = "that's great!";

char *text;

text = "Whee, you have ";

//and here's where the function would be...
//i'm making up a name for it ;)
buffer_printf (text,"%i apples and %i bananas! %s",x,y,blah);

---

output being, "Whee, you have 50 apples and 100 bananas! that's great!"

yes, there is one, it's called sprintf, the first param is the buffer.

>char *text;
Better give text some memory:
char text[100];

>buffer_printf (text,"%i apples and %i bananas! %s",x,y,blah);

sprintf?
sprintf (text,"Whee, you have %i apples and %i bananas! %s",x,y,blah);

but doesn't sprintf fill the buffer, and not append to it?

Code:

---

sprintf (text + strlen(text),"%i apples and %i bananas! %s",x,y,blah);

---

strcat() will concatenate ( aka append) one C style string onto another.

And then there's C++ output:

Code:

---

cout << text << x << " apples and " << y << " bananas! " << blah;

If you have to do this repeatedly, you can write your own function that accepts some numbers and strings and outputs them in the correct order.
