Given a character, we need to print its ASCII value in C/C++/Java/Python.

Examples :

Input : a
Output : 97

Input : D
Output : 68

Here are few methods in different programming languages to print ASCII value of a given character :

Python code using ord function : ord() : It converts the given string of length one, returns an integer representing the Unicode code point of the character. For example, ord(‘a’) returns the integer 97.

Python

   # Python program to print 
# ASCII Value of Character
 
# In c we can assign different
# characters of which we want ASCII value 
 
c = 'g'
# print the ASCII value of assigned character in c
print("The ASCII value of '" + c + "' is", ord(c))
 
  

Output

("The ASCII value of 'g' is", 103)

Time Complexity: O(1)
Auxiliary Space: O(1)

C code: We use format specifier here to give numeric value of character. Here %d is used to convert character to its ASCII value.

C

   // C program to print
// ASCII Value of Character
#include <stdio.h>
int main()
{
    char c = 'k';
 
    // %d displays the integer value of a character
    // %c displays the actual character
    printf("The ASCII value of %c is %d", c, c);
    return 0;
}
 
  

Output

The ASCII value of k is 107

Time Complexity: O(1)
Auxiliary Space: O(1)

C++ code: Here int() is used to convert a character to its ASCII value.

CPP

   // CPP program to print
// ASCII Value of Character
#include <iostream>
using namespace std;
int main()
{
    char c = 'A';
    cout << "The ASCII value of " << c << " is " << int(c);
    return 0;
}
 
  

Output

The ASCII value of A is 65

Time Complexity: O(1)
Auxiliary Space: O(1)

Java code : Here, to find the ASCII value of c, we just assign c to an int variable ascii. Internally, Java converts the character value to an ASCII value.

Java

   // Java program to print
// ASCII Value of Character
public class AsciiValue {
 
    public static void main(String[] args)
    {
 
        char c = 'e';
        int ascii = c;
        System.out.println("The ASCII value of " + c + " is: " + ascii);
    }
}
 
  

Output

The ASCII value of e is: 101

Time Complexity: O(1) // since no loop is used the algorithm takes up constant time to perform the operations
Auxiliary Space: O(1) // since no extra array is used so the space taken by the algorithm is constant

C# code : Here, to find the ASCII value of c, we just assign c to an int variable ascii. Internally, C# converts the character value to an ASCII value.

CSHARP

   // C# program to print
// ASCII Value of Character
using System;
 
public class AsciiValue 
{
    public static void Main()
    {
 
        char c = 'e';
        int ascii = c;
        Console.Write("The ASCII value of " + 
                        c + " is: " + ascii);
    }
}
 
// This code is contributed 
// by nitin mittal
 
  

Output

The ASCII value of e is: 101

Time Complexity: O(1)
Auxiliary Space: O(1)

JavaScript code: Here, to find the ASCII value of the character, the charCodeAt() method is used to get the ASCII value of the character at a specific index in a string.

Javascript

   // JavaScript program to print
// ASCII Value of Character
 
console.log("The ASCII value of " + 'A' + " is " + 'A'.charCodeAt(0));
 
// This Code is Contributed by Prasad Kandekar(prasad264)

Output:

The ASCII value of A is 65

Time Complexity: O(1)
Auxiliary Space: O(1)

Here is a method to print the ASCII value of the characters in a string using python:

Python3

   print("Enter a String: ", end="")
text = input()
textlength = len(text)
for char in text:
    ascii = ord(char)
    print(char, "\t", ascii)
 
  

Input:

Enter a String: Aditya Trivedi

Output:

Time Complexity: O(N), where N is the length of the input string.
Auxiliary Space: O(1)
