How can I count the number of characters that are printed as output?

Question

Does anyone know how I can print and count the number of characters that I printed?

Say I have a number I am printing via printf or cout. How could I count the actual number of digits I have printed out?

Answer 1

According to the printf man page, printf returns the number of characters printed.

int count = printf("%d", 1000);

If an output error is encountered, a negative value is returned.

Answer 2

printf returns the number of characters it printed
