C++ program to convert numbers to words

If you are looking for a C++ program to convert numbers to words, you can find a good C++ program here which can convert numbers to words up to 5 digits.



here is the program:



#include<iostream.h>

#include<conio.h>

void single(int);

void ten2ninety(int);

void elev2nine(int);

void dig2word(int);

void main()

{

clrscr();

int a;

cout<<"\n Enter a number\n";

cin>>a;

dig2word(a);

getch();

}

void dig2word(int y)

{

int s=y,ctr=0,ldig,sdig,l2dig,l3dig,l3rddig;

while(y>0)

{

y=y/10;

++ctr;

}

if(ctr==1)

{

single(s);

return;

}

else if(ctr==2)

{

ldig=s%10;

s=s/10;

sdig=s%10;

 if(ldig==0)

 {

   ten2ninety(sdig);

   return;

 }

 if(sdig==1)

 {

 elev2nine(ldig);

 return;

 }

ten2ninety(sdig);

single(ldig);

return;

}

       else if(ctr==3)

       {

l2dig=s%100;

s=s/100;

sdig=s%10;

if(l2dig==0)

{

single(sdig);

cout<<" Hundred";

return;

}

else

{

single(sdig);

cout<<" Hundred";

dig2word(l2dig);

return;

}

       }

       else if(ctr==4)

       {

l3dig=s%1000;

s=s/1000;

sdig=s%10;

if(l3dig==0)

{

single(sdig);

cout<<" Thousand";

return;

}

else

{

single(sdig);

cout<<" Thousand";

dig2word(l3dig);

return;

}

       }

      else if(ctr==5)

       {

l2dig=s%100;

l3dig=s%1000;

s=s/100;

l3rddig=s%10;

s=s/10;

if(l2dig==0&&l3rddig==0)

{

dig2word(s);

cout<<"Thousand";

return;

}

dig2word(s);

cout<<"Thousand";

dig2word(l3dig);

return;

       }

}

void single(int x)

{

 switch(x)

 {

  case 0:cout<<" Zero ";break;

  case 1:cout<<" One ";break;

  case 2:cout<<" Two ";break;

  case 3:cout<<" Three ";break;

  case 4:cout<<" Four ";break;

  case 5:cout<<" Five ";break;

  case 6:cout<<" Six ";break;

  case 7:cout<<" Seven ";break;

  case 8:cout<<" Eight ";break;

  case 9:cout<<" Nine ";break;

 }

}

void elev2nine(int x)

{

 switch(x)

 {

  case 1:cout<<" Eleven ";break;

  case 2:cout<<" Tweleve ";break;

  case 3:cout<<" Thirteen ";break;

  case 4:cout<<" Fourteen ";break;

  case 5:cout<<" Fifteen ";break;

  case 6:cout<<" Sixteen ";break;

  case 7:cout<<" Seventeen ";break;

  case 8:cout<<" Eighteen ";break;

  case 9:cout<<" Nineteen ";break;

 }

}

void ten2ninety(int x)

{

 switch(x)

 {

  case 1:cout<<" Ten ";break;

  case 2:cout<<" Twenty ";break;

  case 3:cout<<" Thirty ";break;

  case 4:cout<<" Forty ";break;

  case 5:cout<<" Fifty ";break;

  case 6:cout<<" Sixty ";break;

  case 7:cout<<" Seventy ";break;

  case 8:cout<<" Eighty ";break;

  case 9:cout<<" Ninety ";break;

 }

}

 

The above program works best for integer limit that means up to 32767 but if you want up to 99999. convert all "int" to "long int"
