If the user inputs 1, 10, 12 , the output of the following program are:
           1: *
*******10: **********
*******12: ************

How can I get the following output?
       1: *
     10: **********
     12: ************

 

#include <iostream.h>
#include <iomanip.h>
int main(){
    int a,b,c;
    cout << "Please enter three integers:" ;
    cin >> a >> b >> c ;
    cout <<setw(9) <<  a << ": " << setw(a+1) << setfill('*') << endl
             <<setw(9) <<  b << ": " << setw(b+1) << setfill('*') << endl
             <<setw(9) << c <<": " << setw(c+1) << setfill('*') << endl;
   
    return 0;
}

I'm sorry, didn't realize you needed the leading spaces, this should fix that.

#include <iomanip.h>
#include <iostream.h>

int main(){

int a,b,c;
cout << "Please enter three integers:" ;
cin >> a >> b >> c ;
cout << "    " <<setw(2) <<a << ": " << setw(a+1) << setfill('*') << endl
<< "    " <<setw(2) <<b << ": " << setw(b+1) << setfill('*') << endl
<< "    " <<setw(2) << c <<": " << setw(c+1) << setfill('*') << endl;
 
return 0;
}

If the user inputs number 100, your program will not be correct.

Why? Because the screen isn't 100 chars wide?  I don't remember reading anything in the specs that said the goofy program had to handle input of 100.  The numbers given were 1, 10, 12.  How can you expect me to write a program to generate "correct" results if the "correct result" was never specified?  What the hell do you need this for anyway?
