need help

[lblock]

this is what i have and i need to display the actual number name not the number itself.
#include <cstdlib>
#include <iostream>
using namespace std;


int main()
{
int beers=99;
while (beers>0)
{

cout <<beers <<" bottles of beer on the wall"<< endl;
cout<< beers <<" bottles of beer"<< endl;
beers--;
cout << "Take one down pass it around" <<endl;
cout << beers << " bottles of beer on the wall"<< endl;
cout << endl;
}



system ("Pause");
return 0;
}

If you want the number beers as text then you will have to write it

change

cout << beers << " bottles of beer on the wall"<< endl;

to

cout << NumberString(beers) << " bottles of beer on the wall"<< endl;

Then define the function

#include <string>
using namespace std;
 
string NumberString(unsigned number)
{
    string result = "";
// Handle special cases of number,
//               11, 12, 13, 14, 15, 16, 17 ,18, 19
//               and finally number > 99
    if (number > 99)
    {
        result = "lots";
    }
    else
    {
        switch(number)
        {
        case 11:
            result = "eleven";
            break;
 
// handle other special cases
 
        default:
            // Get tens digit
            switch(number/10)
            {
            case 0:
                break;
 
            case 2:
                result += "twenty";
                break;
            // etc
            }
 
            if (number >= 20)
            {
                result += " ";
            }
 
            // Get units digit
            switch(number%10)
            {
            case 1:
                result += "one";
                break;
 
            case 2:
                result += "two";
                break;
            // etc
            }
        }
    }
 
    return string;
}

this is what i have now but still having the same problem with not being able to display the number name and not the number. thank for the last help.

one small change..

in the method void print_num_in_english(int num)

string result is not printed.

before return; statment add cout<<result;

now i have this and it displaies all of the right ones through ten and then when it gets to the teens it displaies "nineteen nine bottels of beer on the wall. it never even gets to the other numbers it will start over again with zero after nineteen nine.

That is because the structure you have is slightly wrong the switch for units should be inside the first switch statement and you are missing a "default:" just before the switch for 10's.

The basic structure is

switch(num)
{
case special_case:
  handle special case
  break;
 
case next_special_case:
  handle next special case
  break;
 
// other special cases
 
default:
  // handle general case
  switch to get 10's string
 
  switch to get units string
  break;
}
 

also please use [code] [/code] round your code, if maintains white space and makes it easier to read.
