If a number 972 is entered through the keyboard, your program should print “Nine Seven Two”. Write the program such that it does this for any positive integers.

#include <stdio.h>
#include<conio.h>
int main ()
{
    char a[100];
    int i;
   
clrscr();
    printf("Enter a number: ");
    gets(a);
    for(i=0;i<a[i];i++)
    {
if(a[i]=='0')
   printf("Zero ");
else if(a[i]=='1')
   printf("One ");
else if(a[i]=='2')
   printf("Two ");
else if(a[i]=='3')
   printf("Three ");
else if(a[i]=='4')
   printf("Four ");
else if(a[i]=='5')
   printf("Five ");
else if(a[i]=='6')
   printf("Six ");
else if(a[i]=='7')
   printf("Seven ");
else if(a[i]=='8')
   printf("Eight ");
else if(a[i]=='9')
   printf("Nine ");
    }
    getch();
}
