Thread: Formatting an integer

cout<<"0"<<index<<endl;

Code:

#include <iostream>

using namespace std;

int main()
{
    int index = 6;
    cout.fill('0');
    cout.width(2);
    cout << index << endl;
    return 0;
}

Or...

Code:

#include <iostream>
#include <iomanip>

using namespace std;

int main()
{
    int index = 6;
    cout << setfill('0') << setw(2) << index << endl;
    return 0;
}

Each time you output a value, things will go back to the defaults so you will need to reapply the fill and width commands before each value you are outputting.

or u could prolly jus say

int var = 06;
cout<<var<<endl;

Nope, won't work if you do that.

hmm i guess i should of tested it first

You would think this is nuclear science...





>>>cout<<"0"<<index<<endl;
