Console writing, delete characters

Question

My question concerns deleting already written chars in the console. Is there a way to do it? Lets say i write 10 spaces to the console. Can i delete some to make space for other chars without the output exeeding 10 chars? I use a special libary given, with functions for writing in the console etc.

Answer 1

Use '\b'. It erases one character, and the cursor moves back:

std::cout << "nawaz"; //screen shows : nawaz
std::cout << '\b'; //'z' is erased, now screen shows : nawa

Answer 2

do {

cout<<"\b"<<num--;

}

while ( num >0 );
