Question

Im making a class that is supposed to be able to assign c-strings the same way the string class i able to:

string a = "My string";

The issue I’m having is that it seams like it is not the operator=( char operand ) that is used for this purpose. So my question is this: What is used instead?

What I have:

class exstring
{
    ...

    public:
    exstring& operator=( char* );

    ...
};

...

int main()
{
    exstring test = "test";
}

Which gives:

main.cpp:9:22: error: conversion from ‘const char [19]’ to non-scalar type ‘std::exstring’ requested

Any ideas?

Answer 1

You are not calling your operator = here. You need to learn the difference between assignment and initialization. What you’re doing is initialization and you need a constructor that takes the parameter you’re providing. In other words:

extring test = "test";

Is exactly the same as:

extring test("test");

Except that in the latter case the constructor could be explicit, but not in the former.
