Your local variable mid is declared in the scope that is closer to the point of use, so it “shadows” the mid() function; the compiler thinks that you are trying to “call” an integer, which is invalid. Rename the local variable to fix this problem: Note: you could also use ::mid(lo, hi) instead of renaming … Read more
Your SortedContainerImpl class has two separate Container base classes. One is virtual (via the SortedContainer class) and the other is non-virtual (via the ContainerImpl class). SortedContainerImpl has concrete implementations of Container::get_size() and Container::get(int) for the base that comes in from ContainerImpl, but not for the virtual base that comes in via SortedContainer. One way to … Read more
You can use Scanner with System.in. E.g.
You could use std::set or std::multiset (if you will allow repeated items) of strings, and it will keep the items sorted automatically (you could even change the sorting criteria if you want). input: Gerardo Carlos Kamilo Angel Bosco output:
I believe this is a MinGW/gcc compiler issue, rather than a Microsoft Visual Studio setup. The libgcc_s_dw2-1.dll should be in the compiler’s bin directory. You can add this directory to your PATH environment variable for runtime linking, or you can avoid the problem by adding “-static-libgcc -static-libstdc++” to your compiler flags. If you plan to distribute the … Read more
“Slicing” is where you assign an object of a derived class to an instance of a base class, thereby losing part of the information – some of it is “sliced” away. For example, So an object of type B has two data members, foo and bar. Then if you were to write this: Then the information in b about member bar is lost in a.
It’s possible to use static const int member as an array size, but you’ll have to define this member within class in your .hpp file like so: This will work. P.S. About the logic behind it, I believe compiler wants to know size of the array member as soon as it encounters class declaration. If you leave static const … Read more
Your functions should be:- REASON FOR THIS BEHAVIOR :- When you re-define a function in derived class with same parameters as in base class then that’s called as overriding. Whereas if you re-define that function with different parameter then it would be an attempt to use overloading from you side. But overloading is possible only … Read more
Conventions. Historically, the suffix for a C++ source file was .C. This caused a few problems the first time C++ was ported to a system where case wasn’t significant in the filename. Different users adopted different solutions: .cc, .cpp, .cxx and possibly others. Today, outside of the Unix world, it’s mostly .cpp. Unix seems to use .cc more often. For headers, the situation … Read more
