Answer 1

You can use a "carriage return" (\r) without a line-feed (\n), and hope your console does the right thing.

Answer 2

Another way could be showing the "Dots" or any character you want .The below code will print progress indicator [sort of loading...]as dots every after 1 sec.

PS : I am using sleep here. Think twice if performance is concern.

#include<iostream>
using namespace std;
int main()
{
    int count = 0;
    cout << "Will load in 10 Sec " << endl << "Loading ";
    for(count;count < 10; ++count){
        cout << ". " ;
        fflush(stdout);
        sleep(1);
    }
    cout << endl << "Done" <<endl;
    return 0;
}
