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.
