Given an integer N, the task is to print the ASCII value of all digits of N.
Examples:
Input: N = 8
Output: 8 (56)
Explanation:
ASCII value of 8 is 56Input: N = 240
Output:
2 (50)
4 (52)
0 (48)
Approach: Using the ASCII table shown below, the ASCII value of all the digits of N can be printed:
| Digit | ASCII Value |
| 0 | 48 |
| 1 | 49 |
| 2 | 50 |
| 3 | 51 |
| 4 | 52 |
| 5 | 53 |
| 6 | 54 |
| 7 | 55 |
| 8 | 56 |
| 9 | 57 |
It can be observed that ASCII value of digits [0 – 9] ranges from [48 – 57]. Therefore, in order to print the ASCII value of any digit, 48 is required to be added to the digit.
Below is the implementation of the above approach:
C++
// C++ program to convert the digits// of a number to its ASCII values#include <iostream>using namespace std;Â
// Function to convert digits of// N to respective ASCII valuesint convertToASCII(int N){Â Â Â Â while (N > 0) {Â Â Â Â Â Â Â Â int d = N % 10;Â Â Â Â Â Â Â Â cout << d << " ("Â Â Â Â Â Â Â Â Â Â Â Â Â << d + 48 << ")\n";Â
        N = N / 10;    }}Â
// Driver Codeint main(){Â Â Â Â int N = 36;Â Â Â Â convertToASCII(N);Â
    return 0;} |
Java
// Java program convert the digits// of a number to its ASCII valuesimport java.io.*;class GFG {Â
    // Function to convert digits of    // N to respective ASCII values    static void convertToASCII(int N)    {        while (N > 0) {            int d = N % 10;            System.out.println(d + " ("                               + (d + 48) + ")");Â
            N = N / 10;        }    }Â
    // Driver Code    public static void main(String[] args)    {        int N = 36;        convertToASCII(N);    }} |

Alternate Approach: The idea is to use type conversion. Convert the integer to equivalent string and print ASCII value of each character of the string.
Below is the implementation of the above approach:Â
C++
// C++ program to convert the digits// of a number to its ASCII values#include <bits/stdc++.h>using namespace std;Â
// Function to convert digits of// N to respective ASCII valuesint convertToASCII(int N){Â Â Â Â string num = to_string(N);Â Â Â Â for (char ch : num) {Â Â Â Â Â Â Â Â cout << ch << " ("Â Â Â Â Â Â Â Â Â Â Â Â Â << (int)ch << ")\n";Â Â Â Â }}Â
// Driver Codeint main(){Â Â Â Â int N = 36;Â Â Â Â convertToASCII(N);Â
    return 0;} |
Java
// Java program to convert the digits// of a number to its ASCII valuesimport java.util.*;class GFG{Â Â // Function to convert digits of// N to respective ASCII valuesstatic void convertToASCII(int N){Â Â Â Â String num = Integer.toString(N);Â Â Â Â for (char ch : num.toCharArray()) {Â Â Â Â Â Â Â Â System.out.print(ch + " ("Â Â Â Â Â Â Â Â Â Â Â Â + (int)ch + ")\n");Â Â Â Â }}Â Â // Driver Codepublic static void main(String[] args){Â Â Â Â int N = 36;Â Â Â Â convertToASCII(N);}}Â Â // This code is contributed by sanjoy_62. |
