I want my clock program to display the output as 00:00 instead it displays it as 0:0 even though I h-CodePudding

So I made a sloppy clock program as an assignment. It works fine however I want the output to display each cout as "01:02", instead it displays "1:2", even though I think I have written all the right manipulators. This is my whole program.

#include <thread>
#include <chrono>
#include <iostream>
#include <iomanip>
#include <ctime>
#include <stdlib.h>
using namespace std;
int main()
{
    cout << fixed << right;
    cout.fill(0);
    for (int m = 0; m < 59; m  )
    {
        for (int s = 0; s < 59; s  )
        {
            this_thread::sleep_for(
                chrono::seconds(1));
            system("cls");
            cout << setw(2) << m << ":";
            cout << setw(2) << s << endl;
        }
    }
}

CodePudding user response：

You also need to do a setfill('0') in addition with setw().

setw() simply sets the minimum width for the formatted output operation. The unused part of the field's width defaults to spaces. setfill() changes that.

CodePudding user response：

You are using the null character to fill (which is not visible).

cout.fill(0);

What you probably meant was to use the ASCII character 0, like this:

cout.fill('0');
