void main()

{

long n,x=100000000;

printf("Enter upto 9 digit number\n");

scanf("%ld",&n);

if(n<=0)

printf("Enter a positive number\n");

else

{

//This will truncate zeros at start if any and if not present then set value of x appropriately

while(((n/x)%10)==0)

x=x/10;

//Actual logic to print words starts here

while(x>0)

{

pw((n/x)%10);

x/=10;

}

}

}

void pw(long n)

{

printf("%s",unit[n]);

}
