A conversion constructor is basically a constructor that take a single argument of one type (different from the class), and uses it to initialize the object.

Lets say you have the following class:

struct Foo
{
    Foo() = default;  // Defaulted default constructor

    // Conversion constructor, allows construction from int values
    Foo(int)
    {
    }
};

Then you can create Foo object with an int value:

Foo f = 1;  // Equivalent to Foo f = Foo(1)

It also allows assignments from int values:

f = 2;  // Equivalent to f = Foo(2)
