C++ Program to Find ASCII Value of a Character

A character variable holds ASCII value (an integer number between 0 and 127) rather than that character itself in C programming. That value is known as ASCII value.

For example, ASCII value of ‘A’ is 65.

What this means is that, if you assign ‘A’ to a character variable, 65 is stored in that variable rather than ‘A’ itself.

Resource: ASCII chart of all 127 characters in C++.

Example: Print ASCII Value in C++


              
#include <iostream>
using namespace std;

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

Output


              
Enter a character: p
ASCII Value of p is 112

When we explicitly print the integer value of a char type, it’s corresponding ASCII value is printed.
