### Number to word Conversion C Language Program

Question : Write a program which takes number as integer and convert it into string?
i.e
Input : 123
Output : One Hundred Twenty Three Only

#include <stdio.h>
#include <conio.h>
void ntoword(int);
void main()
{
int n;
clrscr();
printf("Enter number>> ");
scanf("%d",&n);
ntoword(n);
getch();
}
void ntoword(int n)
{
char *one[]={"Zero","One","Two","Three","Four","Five","Six","Seven","Eight","Nine"};
char *two[]={"Ten","Eleven","Twelve","Thirteen","Fourteen","Fifteen","Sixteen","Seventeen","Eighteen","Nineteen"};
char *three[]={"","Twenty","Thirty","Fourty","Fifty","Sixty","Seventy","Eighty","Ninety"};
int ar[3],i,j;
i=n>99?2:n>9?1:0;
for(j=n;j>0;j/=10,i--)
ar[i]=j%10;
if(n>999)
printf("out of range");
else
{
if(n>99) /* for three digit*/
{
printf("%s Hundred ",one[ar[0]]);
if(ar[1]>1)
{
printf(" %s %s Only",three[ar[1]-1],one[ar[2]]);
}
else
{
printf("%s Only",two[ar[2]]);
}
}
else if(n>9) /*for two Digit */
{
if(ar[0]>1)
{
printf(" %s %s Only",three[ar[0]-1],one[ar[1]]);
}
else
{
printf(" %s Only",two[ar[1]]);
}

}
else   /*One Digit Only */
{
printf("%s only",one[ar[0]]);
}
}

}
