如何使用重载 == 运算符将 class 中的 char 数组与另一个 char 数组进行比较？

Question

I have a class called Airplane with a private data member thats a char array.

// char array variable in my class
char* name{nullptr};

my goal is to compare for equality this variable and an input variable of type const char [].

my overload function looks like this:

bool Airplane::operator==(const char input_name[]) const{
    if (this->name == input_name) {
         return true;
     }
return false;
}

By overloading the == operator, I want to be able to do the following:

Airplane plane("hello");
if (plane == "hellooo") {
   // do something
}

I want to be able to create a class with a text variable like "hello" and then be able to == it to any random text I want to compare equality. Right now my code just doesnt work, it runs and then ends in the console with no errors. basically I need to compare to char arrays, one within the class the overload function is built in, and another given as input by the user. Thank you for any help.

As @PaulMcKenzie has rightly said, char* is not an array.

I suggest using std::string instead of char* as well as in overload as follows:

const bool Airplane::operator==(const std::string& str_to_be_compared) const {
    return this->(whatever variable stores the name of the plane) == str_to_be_compared;
}
