formatting - Should I use printf in my C++ code?

Question

I generally use cout and cerr to write text to the console. However sometimes I find it easier to use the good old printf statement. I use it when I need to format the output.

One example of where I would use this is:

// Lets assume that I'm printing coordinates... 
printf("(%d,%d)
", x, y);

// To do the same thing as above using cout....
cout << "(" << x << "," << y << ")" << endl;

I know I can format output using cout but I already know how to use the printf. Is there any reason I shouldn't use the printf statement?

Answer 1

My students, who learn cin and cout first, then learn printf later, overwhelmingly prefer printf (or more usually fprintf). I myself have found the printf model sufficiently readable that I have ported it to other programming languages. So has Olivier Danvy, who has even made it type-safe.

Provided you have a compiler that is capable of type-checking calls to printf, I see no reason not to use fprintf and friends in C++.
