C++ Change Output From "cout"

Question

Is it possible to change text printed with "cout"? I would like to make it show the current percentage of something without having to have a new line for each percentage. Is this possible?

Answer 1

This works for me:

std::cout << "1111";
std::cout << "\r";
std::cout << "2222";

\r is a carriage return symbol. Puts the "cursor" back to the beginning of the line.

Alternatively you can use \b character. This is backspace. When printed it goes one character back.
