static memory allocation like dynamic memory allocation

int r, c;
cin >> r >> c;
int matrix[r][c];

I'm not sure what the point of runtime allocation is.

The goal is to allocate memory during runtime, but we're doing the same thing in the code above.

When this section of code is executed, the input sizes are specified at runtime, and the matrix is allocated memory based on the size of the rows and columns, so how is this allocation static or compile time?

Cases of static and dynamic binding in C++

When an object's static type is used to associate it with a member function, this is known as static binding (understand the type of its class). When a pointer or reference is associated with a member function based on the dynamic type of the object, this is known as dynamic binding (understand the instance of the variable at runtime). Before continuing, keep in mind that dynamic binding only works with pointers, references, and virtual functions for the base class. Because everything needed to call the function is known at compile time, the first call is a static binding (also known as early binding). Derived1 d1(1, 10); d1.display_data(); You already know that the d1 instance is a Derived1 automatic variable, and that it will call the Derived1::display data method (). The first condition is incorrect: d1 is neither a pointer nor a reference. The second condition isn't acceptable: There is no virtual Derived1::display data. The second call is for ...READ MORE

The static keyword and its various uses in C++

Static variables exist during the "lifetime" of the translation unit in which they are declared, and: It cannot be accessible from any other translation unit if it is in a namespace scope (i.e. outside of functions and classes). This is referred to as "internal linking" or "static storage lifetime." (Except for constexpr, do not do this in headers; otherwise, you would wind up with a different variable in each translation unit, which is really confusing.) If it is a variable in a function, it, like any other local variable, cannot be accessed from outside the function. (This is the mentioned local) Class members have no limited scope owing to static, but they may be referenced from both the class and an instance (like std::string::npos). locations as code: static std::string namespaceScope = "Hello"; void ...READ MORE

How to access static members of a class?

I'm learning C++ and Qt, but even the simplest code that I copy and paste from a book produces problems. On Ubuntu 10.04, I'm using g++4.4.2 with the QtCreator IDE. Is there a distinction between the syntax of the g++ compiler and those of other compilers? When I try to access static members, for example, something always goes wrong. #include <iostream> using namespace std; class A { ...READ MORE
