How to initialize a char array in a constructor with C++

Answer 1

#include <iostream>
#include <cstring> // Include cstring for strcpy or memcpy

class MyString {
private:
    char arr[128] = "";

public:
    MyString();
    void display() const {
        std::cout << arr << std::endl;
    }
};

MyString::MyString() {
    static char const data[] = "C++ Programming";

    std::strcpy(arr, data); // Or std::memcpy(arr, data, sizeof(data));
}

int main() {
    MyString().display();
}
