Observations: #include <cstring> should introduce std::strcpy(). using namespace std; (as written in medico.h) introduces any identifiers from std:: into the global namespace. Aside from using namespace std; being somewhat clumsy once the application grows larger (as it introduces one hell of a lot of identifiers into the global namespace), and that you should never use … Read more
It says that low and high are “redeclared as different type of symbol” and I don’t know what that means. Basically, all I’m doing here (READ: trying) is integrating from low (which I set to 0) to high (20) to find the Riemann sum. The for loop looks kinda trippy too…I’m so lost. EDIT: ^That … Read more
According to the C++ reference (here) getline sets the ios::fail when count-1 characters have been extracted. You would have to call filein.clear(); in between the getline() calls.
A zero-size vector of pointers: A vector of NULL pointers: A vector of pointers to newly allocated objects (not really initialization though): Initializing a vector of pointers to newly allocated objects (needs C++11): A smarter version of #3:
getName is not const, getScore is not const, but print is. Make the first two const like print. You cannot call a non-const method with a const object. Since your Person objects are direct members of your other class and since you are in a const method they are considered const. In general you should … Read more
In order to declare a variable of any type, template or not, the entire definition of that type must be available. You cannot forward-declare a template, and then start using it as if it were defined. All you can do at that point is declaring a pointer to an object of a type based on … Read more
I would recommend reading a book on C++ before you go any further, as it would be helpful to get a firmer footing. Accelerated C++ by Koenig and Moo is excellent. To get the executable path use GetModuleFileName: Here’s a C++ function that gets the directory without the file name:
The problem is that the function list::Subset(list subset) takes its argument by value causing a copy of the list to be made. Since you did not follow the Rule of Three (as noted in Chris’ comment) a shallow copy is made. This means that two instance of list “own” the pointers. When the Subset function … Read more
The reason the base class is abstract is this pure virtual function: The derived class DisablePairCollision attempts to define that function, but it does not do it correctly: As you can see, some of the arguments have different types. E.g. colObj0 is of type const btCollisionObject*, but it should be of type const btCollisionObjectWrapper*. Therefore, … Read more
Seeing from your G++ version, you need to update it badly. C++11 has only been available since G++ 4.3. The most recent version is 4.7. In versions pre-G++ 4.7, you’ll have to use -std=c++0x, for more recent versions you can use -std=c++11.
