Thread: Numbers to words

So i'm currently reading the website host book, and one of the situations we are addressed with is converting numbers into their text, e.g. 103; one hundred three. Well i was able to finally get all my code to work. But i'm wondering if i didn't go about this very efficiently can somebody look over my code and tell me? Also I'm not using pointers yet i think that might have made this easier but not too sure.

Code:

#include <iostream>

using namespace std;


int tens(int remainder);
int hundreds(int x);
int thousands(int x);
void numtoword(int x);
void hardcode(int x);










int main()
{
    int x;
    cout<<"What number do you want to convert to text?\n";
    cin>>x;
    numtoword(x);


    return 0;
}








void numtoword(int x)
{
    if (x < 20){
        hardcode(x);
    }
    else if (x > 99 && x < 1000){
        hundreds(x);
    }
    else if(x > 999 && x < 1000000){
        thousands(x);
    }




}




void hardcode(int x)
{
    if(x == 1){
        cout<<" One ";
    }
    else if(x == 2){
        cout<<" Two ";
}
    else if(x == 3){
        cout<<" Three ";
    }
    else if(x == 4){
        cout<<" Four ";
    }
    else if(x == 5){
        cout<<" Five ";
    }
    else if(x == 6){
        cout<<" Six ";
    }
    else if(x == 7){
        cout<<" Seven ";
    }
    else if(x == 8){
        cout<<" Eight ";
    }
    else if(x == 9){
        cout<<" Nine ";
    }
    else if(x == 10){
        cout<<" Ten";
    }
    else if(x == 11){
        cout<<" Eleven";
    }
    else if(x == 12){
        cout<<" Tweleve";
    }
    else if(x == 13){
        cout<<" Thirteen";
    }
    else if(x == 14){
        cout<<" Fourteen";
    }
    else if(x == 15){
        cout<<" Fifteen";
    }
    else if(x == 16){
        cout<<" Sixteen";
    }
    else if(x == 17){
        cout<<" Seventeen";
    }
    else if(x == 18){
        cout<<" Eighteen";
    }
    else if(x == 19){
        cout<<" Nineteen";
    }
}




int thousands(int x)
{
        int firstnum = x/1000;
        int bignum = x % 1000;
        while(x > 1000){
