When discussing data types in Python, we must start with the standard data types. The standard data types in Python are as follows: Numeric Types: Numeric data types are used to store numerical values. They are immutable data types, meaning that changing a numeric data type will allocate a new object. In Python 2.X, there … Read more

Storage classes are used to define the lifetime and visibility of variables and/or functions in a C++ program. The lifetime refers to the duration during which a variable remains active, and visibility refers to the modules in the program that can access the variable. In C++ programs, there are five types of storage classes that … Read more
Like other programming languages, in C++, an array is a collection of similar types of elements with contiguous memory locations. In C++, std::array is a container that encapsulates fixed-size arrays. In C++, array indexing starts at 0. We can only store a fixed number of elements in a C++ array. In C/C++ programming languages or … Read more
So far, we have learned about the two types of variables supported by C++: Ordinary variables are variables that hold values of a certain type. For example, creating an integer variable means that the variable can hold integer values. Pointers are variables that store the address of another variable. You can retrieve the value pointed … Read more
