C++ Program to find ASCII value of character

In this example, you will learn how to find the ASCII value of a character in C++.

What are ASCII values?

ASCII (American Standard Code for Information Interchange) is the most common character encoding format for text data on computers and the internet. In standard ASCII-encoded data, there are unique values for 128 alphabetic, numeric, or special additional characters and control codes.
The ASCII value of A to Z is the ASCII characters from 33 to 126.

How to get the ASCII value of a character in C++?

Ask the user to enter any character. Read the character into a character type variable ch. Get the ASCII value of the character by using the function int(expression).
The int(expression) function returns the numeric integer equivalent to a given expression.
Int(ch) will return the numerical value of the entered character.

Algorithm

Step 1:  Call the header file iostream.

Step 2: Use the namespace std.

Step 3: Open the integer type main function; int main().

Step 4: Declare character type variable ch;

Step 5: Print a message to enter a character.

Step 6: Read the character into the variable ch

Step 7: Get the numerical value of the entered character by using the function int (ch)

Step 8: Print the value

Step 9: Exit.
 

C++ Source Code

                                          #include <iostream>
using namespace std;

int main() {
 char ch;
 cout << "Enter a character: ";
 cin >> ch;
 cout << "ASCII Value of " << ch << " is " << int(ch);
 return 0;
}
                                      

OUTPUT

Run 1
Enter a character: 4
ASCII Value of 4 is 52
Run 2
Enter a character: t
ASCII Value of t is 116
