How to Convert ASCII Value into char in C++?

In C++, ASCII (American Standard Code for Information Interchange) values are numerical representations of characters that are used in the C++. In this article, we will learn how to convert an ASCII value to a char in C++.

Example:

Input: 
int asciiValue = 65; 

Output: 
Character for ASCII value 65 is: 'A'

Convert ASCII Value to char in C++

To convert an ASCII value to a char, we can simply type-cast an integer (ASCII value) to a char type or directly use the char() function, which basically performs the same operation as type casting.

Syntax to Convert ASCII to Char in C++

char charName = (char)asciiValue;   //typecasting to char type
//or
char charName = char(asciiValue);   //directly using char() function

C++ Program to Convert ASCII to Char

The below program demonstrates how we can convert an ASCII value to a char in C++.

// C++ program to convert ASCII to char
#include <iostream>
using namespace std;

int main()
{

    // Define ASCII values for characters 'A' and 'B'.
    int asciiValue1 = 65;
    int asciiValue2 = 66;

    // Typecast the ASCII values to char type
    char character1 = (char)asciiValue1;
    cout << "The character for ASCII value " << asciiValue1
         << " is " << character1 << endl;

    // use char() function tfor conversion
    char character2 = char(asciiValue2);
    cout << "The character for ASCII value " << asciiValue2
         << " is " << character2 << endl;

    return 0;
}

The character for ASCII value 65 is A
The character for ASCII value 66 is B
