char类型可以归类为整数吗

char类型可以归类为整数吗？

c++
#include 
using namespace std;
int main() {
    char c = 'A'; // 字符'A'对应的ASCII码值为65
    int i = c; // 将char类型转换为int类型
    
    cout << "Character: " << c << endl;
    cout << "ASCII value: " << i << endl;
    
    int j = 97;
    char d = j; // 将int类型转换为char类型，对应的ASCII码值为'a'
    
    cout << "Integer: " << j << endl;
    cout << "Character: " << d << endl;
    
    return 0;
}

c++
#include 
using namespace std;
int main() {
    char c = 'A'; // 字符'A'对应的ASCII码值为65
    int i = c + 5; // char类型与int类型相加
    
    cout << "Character: " << c << endl;
    cout << "New ASCII value: " << i << endl;
    
    return 0;
