Program to print the given digit in words

Difficulty Level : Basic
Last Updated : 26 Apr, 2021

Given a number N, the task is to convert every digit of the number into words.
Examples:

Input: N = 1234
Output: One Two Three Four
Explanation:
Every digit of the given number has been converted into its corresponding word.
Input: N = 567
Output: Five Six Seven

Approach: The idea is to traverse through every digit of the number and use switch-case. Since there are only ten possible values for digits, ten cases can be defined inside a switch block. For each digit, its corresponding case block will be executed and that digit will get printed in words.
Below is the implementation of the above approach:

CPP

// C++ implementation of the above approach
 
#include "bits/stdc++.h"
using namespace std;
 
// Function to return the word
// of the corresponding digit
void printValue(char digit)
{
 
    // Switch block to check for each digit c
    switch (digit) {
 
    // For digit 0
    case '0':
        cout << "Zero ";
        break;
 
    // For digit 1
    case '1':
        cout << "One ";
        break;
 
    // For digit 2
    case '2':
        cout << "Two ";
        break;
 
    // For digit 3
    case '3':
        cout << "Three ";
        break;
 
    // For digit 4
    case '4':
        cout << "Four ";
        break;
 
    // For digit 5
    case '5':
        cout << "Five ";
        break;
 
    // For digit 6
    case '6':
        cout << "Six ";
        break;
 
    // For digit 7
    case '7':
        cout << "Seven ";
        break;
 
    // For digit 8
    case '8':
        cout << "Eight ";
        break;
 
    // For digit 9
    case '9':
        cout << "Nine ";
        break;
    }
}
 
// Function to iterate through every
// digit in the given number
void printWord(string N)
{
    int i, length = N.length();
 
    // Finding each digit of the number
    for (i = 0; i < length; i++) {
 
        // Print the digit in words
        printValue(N[i]);
    }
}
 
// Driver code
int main()
{
    string N = "123";
    printWord(N);
    return 0;
}

Java

// Java implementation of the above approach
class GFG
{
 
// Function to return the word
// of the corresponding digit
static void printValue(char digit)
{
 
    // Switch block to check for each digit c
    switch (digit)
    {
 
    // For digit 0
    case '0':
        System.out.print("Zero ");
        break;
 
    // For digit 1
    case '1':
        System.out.print("One ");
        break;
 
    // For digit 2
    case '2':
        System.out.print("Two ");
        break;
 
    // For digit 3
    case '3':
        System.out.print("Three ");
        break;
 
    // For digit 4
    case '4':
        System.out.print("Four ");
        break;
 
    // For digit 5
    case '5':
        System.out.print("Five ");
        break;
 
    // For digit 6
    case '6':
        System.out.print("Six ");
        break;
 
    // For digit 7
    case '7':
        System.out.print("Seven ");
        break;
 
    // For digit 8
    case '8':
        System.out.print("Eight ");
        break;
 
    // For digit 9
    case '9':
        System.out.print("Nine ");
        break;

// Function to iterate through every

    // Finding each digit of the number
    for (i = 0; i < length; i++)
    {

        printValue(N.charAt(i));
    }
}
 
// Driver code
public static void main(String[] args)
{
    String N = "123";
    printWord(N);
}
}
