No == operator found while comparing structs in C++

Question

Comparing two instances of the following struct, I receive an error:

struct MyStruct1 {
    MyStruct1(const MyStruct2 &_my_struct_2, const int _an_int =          


        

Answer 1

Because you did not write a comparison operator for your struct. The compiler does not generate it for you, so if you want comparison, you have to write it yourself.
