Given a character, we need to print its ASCII value in C/C++/Java/Python. 
Examples :
Input : a
Output : 97Input : 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)) |
("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; } |
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; } |
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); } } |
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 |
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:
A 65 d 100 i 105 t 116 y 121 a 97 32 T 84 r 114 i 105 v 118 e 101 d 100 i 105
Time Complexity: O(N), where N is the length of the input string.
Auxiliary Space: O(1)
