I cant understand why result is that

Question

#include <iostream>
using namespace std;

int main() {
char a= 'b';
char b= 'a';
cout << b%a;
return 0;
}
why output is 97 ?

Answer 1

cout << 'a' % 'b'; // 97
// same as:
cout << 97 % 98; // 97
// because:
cout << (int) 'a'; // 97
cout << (int) 'b'; // 98
// or:
cout << (char) 97; // 'a'
cout << (char) 98; // 'b'

The numbers you get are the positions of these chars in the ASCII table.
