How can I erase the current line printed on console in C from the end?

I need to erase a printed character in a new line from the end. That is if the statement is printf("C++") I need to erase those 2 "++" printed and get the output "C".

    printf("hello");   printf("\rbye");

Using the above escape sequence '\r', replaces it only from the printed line beginning to get the output 'byelo', how to do it from the end to get 'hebye'?

You can use the backspace ASCII character:

printf("hello");
printf("\b");

Result:

hell
