# ISC 2011 [Question 1] Practical Paper Solved [Number in Words]

#### Question:

Write a program to input a natural number less than 1000 and display it in words. [Note we have solved the program for numbers in the range [1-9999]

**Test your program for the given sample data and some random data.**

**Sample Data:**

**Input:** 29

**Output:** TWENTY NINE

**Input:** 17001

**Output:** OUT OF RANGE

**Input:** 119

**Output:** ONE HUNDRED AND NINETEEN

**Input: **500

**Output:** FIVE HUNDRED

#### Programming Code:

/** * The class Num2Word_ISC2011 accepts a number in the range [1-9999] and prints it in words. * @author : www.javaforschool.com * @Program Type : BlueJ Program - Java */ import java.io.*; class Num2Word_ISC2011 { public static void main(String args[]) throws IOException { BufferedReader br=new BufferedReader(new InputStreamReader(System.in)); String ty[]={"","","Twenty","Thirty","Forty","Fifty","Sixty","Seventy","Eighty","Ninety"}; String ten[]={"","Ten","Eleven","Twelve","Thirteen","Fourteen","Fifteen","Sixteen","Seventeen", "Eighteen","Nineteen"}; String unit[]={"","One","Two","Three","Four","Five","Six","Seven","Eight","Nine"}; System.out.print("Enter a Number : "); int n=Integer.parseInt(br.readLine()); /*checking whether the number is in the range [1-9999] or not*/ if(n<1 || n>9999) System.out.println("Out of Range"); else { int th=n/1000; //finding the digit at thousand's place int h=(n/100)%10; //finding the digit at hundred's place int t=(n/10)%10; //finding the digit at ten's place int u=n%10; //finding the digit at unit's place System.out.print("Output = "); /*Condition for printing digit at thousand's place, is that it should not be zero*/ if(th!=0) System.out.print(unit[th]+" Thousand"); /*Condition for printing digit at hundred's place, is that it should not be zero*/ if(h!=0) System.out.print(" "+unit[h]+" Hundred"); /*Condition for printing the word "And"*/ if((t!=0 || u!=0)&&(th!=0 || h!=0)) System.out.print(" And"); /*Condition for printing digit at ten's place*/ if(t==1) //When digit at ten's place is 1, we have different words like Ten, Eleven etc. System.out.print(" "+ten[u+1]); else //if it is not 1 then we print the words following a normal pattern System.out.print(" "+ty[t]+" "+unit[u]); } } }

#### Output:

**1.** Enter a Number : 129

Output = One Hundred And Twenty Nine

**2.** Enter a Number : 8307

Output = Eight Thousand Three Hundred And Seven

**3.** Enter a Number : 54987

Out of Range
