程序打印给定数字的所有数字的ASCII值

给定整数N ，任务是打印N的所有数字的ASCII值。

例子：

Input: N = 8
Output: 8 (56)
Explanation:
ASCII value of 8 is 56

Input: N = 240
Output:
2 (50)
4 (52)
0 (48)

方法：使用下面显示的ASCII表，可以打印N的所有数字的ASCII值：

Digit	ASCII Value
0	48
1	49
2	50
3	51
4	52
5	53
6	54
7	55
8	56
9	57

可以看出，数字[0 – 9]的ASCII值范围是[48 – 57] 。因此，为了打印任何数字的ASCII值，需要在数字上添加48。

下面是上述方法的实现：

C++

// C++ program to convert the digits
// of a number to its ASCII values
#include 
using namespace std;
 
// Function to convert digits of
// N to respective ASCII values
int convertToASCII(int N)
{
    while (N > 0) {
        int d = N % 10;
        cout << d << " ("
             << d + 48 << ")\n";
 
        N = N / 10;
    }
}
 
// Driver Code
int main()
{
    int N = 36;
    convertToASCII(N);
 
    return 0;
}

Java

// Java program convert the digits
// of a number to its ASCII values
import java.io.*;
class GFG {
 
    // 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) + ")");
 
            N = N / 10;
        }
    }
 
    // Driver Code
    public static void main(String[] args)
    {
        int N = 36;
        convertToASCII(N);
    }
}

Python3

# Python3 program to convert the digits
# of a number to its ASCII values
 
# Function to convert digits of
# N to respective ASCII values
def convertToASCII(N):
    while (N > 0):
        d = N % 10
        print(d, "(" + str(d + 48) + ")")
        N = N // 10
 
# Driver Code
if __name__ == '__main__':
    N = 36
    convertToASCII(N)

C#

// C# program convert the digits
// of a number to its ASCII values
using System;
public class GFG {
 
  // Function to convert digits of
  // N to respective ASCII values
  static void convertToASCII(int N)
  {
    while (N > 0) {
      int d = N % 10;
      Console.WriteLine(d + " ("
                        + (d + 48) + ")");
 
      N = N / 10;
    }
  }
 
  // Driver Code
  public static void Main(String[] args)
  {
    int N = 36;
    convertToASCII(N);
  }
}

输出：

6 (54)
3 (51)

时间复杂度： O(log ₁₀ N)
辅助空间： O(1)

替代方法：想法是使用类型转换。转换的整数等效的字符串并打印字符串的每个字符的ASCII值。

下面是上述方法的实现：

C++

// C++ program to convert the digits
// of a number to its ASCII values
#include 
using namespace std;
 
// Function to convert digits of
// N to respective ASCII values
int convertToASCII(int N)
{
    string num = to_string(N);
    for (char ch : num) {
        cout << ch << " ("
             << (int)ch << ")\n";
    }
}
 
// Driver Code
int main()
{
    int N = 36;
    convertToASCII(N);
 
    return 0;
}

Java

// Java program to convert the digits
// of a number to its ASCII values
import java.util.*;
class GFG{
  
// Function to convert digits of
// N to respective ASCII values
static void convertToASCII(int N)
{
    String num = Integer.toString(N);
    for (char ch : num.toCharArray()) {
        System.out.print(ch + " ("
            + (int)ch + ")\n");
    }
}
  
// Driver Code
public static void main(String[] args)
{
    int N = 36;
    convertToASCII(N);
}
}
