Making a console progress bar? (Windows)

Question

So I have a function (or rather, I'll turn it into a function later) to make a random % progress in a console window; like this:

#include <iostream>
#include <time.h>
#include <cmath>
#include <windows.h>

using namespace std;

int main()
{
    srand(time(0));
    int x = 0;

    for(int i = 0; i<100; i++){
        int r = rand() % 1000;
        x++;
        cout << "\r" << x << "% completed." << flush;
        if(i < 43){
           Sleep(r/6);
        }else if(i > 43 && i < 74){
           Sleep(r/8);
        }else if(i < 98){
           Sleep(r/5);
        }else if(i > 97 && i != 99){
           Sleep(2000);
        }
    }

    cout << endl << endl << "Operation completed successfully.\n" << flush;
    return 0;
}

The thing is, I want the output to be like this:

1% completed

|

(later...)

25% completed

|||||||||||||||||||||||||

How can I do that?

Thanks in advance!

Answer 1

Printing character '\r' is useful. It puts the cursor at the beginning of the line.

Since you can not access to previous line anymore, you can have something like this:

25% completed: ||||||||||||||||||

After each iteration:

int X;

...

std::cout << "\r" << percent << "% completed: ";

std::cout << std::string(X, '|');

std::cout.flush();

Also, you can use: Portable text based console manipulator
