C - Format char array like printf

Question

I want to format a c string like printf does. For example:

char string[] = "Your Number:%i";
int number = 33;
// String should now be "Your Number:33"

Is there any library or a good way I could do this?

Answer 1

Use sprintf(char* out, const char* format, ... ); like so:

int main() {
  char str[] = "Your Number:%d";
  char str2[1000];
  int number = 33;
  sprintf(str2,str,number);
  printf("%s\n",str2);
  return 0;
}

Output:

---------- Capture Output ----------
> "c:\windows\system32\cmd.exe" /c c:\temp\temp.exe
Your Number:33

> Terminated with exit code 0.
