For this, I need an interface and maybe a container for resolving my instances. But how you do this in C++? In the same way. The difference is that where you “program to an interface” in C#, you “program to a base class” in C++. Additionally, you have extra tools in C++ that you do … Read more
This bit of code here Needs to move to main and slightly transform And that means you’ll need to rethink this loop while(input != “=”) You’re really close. Two suggestions: You can optimize the isOperator function. And since you know there is only one character in the operator, you can use something more elegant than if/else … Read more
UPDATE 2017: In C++17 there is now an official way to list files of your file system: std::filesystem. There is an excellent answer from Shreevardhan below with this source code (This code may throw): Old Answer: In small and simple tasks I do not use boost, I use dirent.h. It is available as a standard header in UNIX, and … Read more
With CMake, it’s generally recommended to do an “out of source” build. Create your CMakeLists.txt in the root of your project. Then from the root of your project: And for Debug (again from the root of your project): Release / Debug will add the appropriate flags for your compiler. There are also RelWithDebInfo and MinSizeRel build configurations. You can modify/add to the flags by specifying a toolchain file in … Read more

Passing by const reference is the preferred way to pass around objects as a smart alternative to pass-by-value. When you pass by const reference, you take the argument in by reference (avoiding making any copies of it), but cannot make any changes to the original object (much as would happen when you would take the parameters in by value). … Read more
