Learning C at University. This is not a homework, but I was trying to do something (some "creative" part of the assignment) and got stuck. I understand that this is possible printf("%d\n", printf("23.4")); // -> 23.44 (i.e. 23.4 + 4 bytes written) but how can I use sprintf() as first argument of printf() ? something like : char * g...
I've written following code: int main() { double A[2]; printf("Enter coordinates of the point (x,y):\n"); scanf("%d,%d", &A[0], &A[1]); printf("Coordinates of the point: %d, %d", A[0], A[1]); return 0; } It's acting like this: Enter coordinates of the point (x,y): 3,5 Coordinates of the point: 3, 267...
I have to create a software that must work on several *nix platforms (Linux, AIX, ...). I need to handle internationalization and my translation strings are in the following form: "Hi %1, you are %2." // English "Vous êtes %2, bonjour %1 !" // French Here %1 stand for the name, and %2 for another word. I may change the format, that's...

Why does the following call: printf("%d %d", 'a', 'b'); result in the "correct" 97 98 values? %d indicates the function has to read 4 bytes of data, and printf shouldn't be able to tell the type of the received arguments (besides the format string), so why isn't the printed number |a||b||junk||junk|? Thanks in advance. ...
printf conversion specifications are % followed by flags, width, precision, length modifier and conversion specifier. Is there practical limit to size of a conversion specification? I.e. %s is 2 chars long, while %08.2f is 6 chars long. My question is, what is the length of the maximal single specification in a format string that can be...

I just discovered that %ws was common knowledge (to some), for formatting unicode strings, as is %wZ - however msdn does not document these in a place I can find them. There are many people who write about these usefull printf format types individually on the web, but no official catch-all that I can find, and hence learn that they exist...
