In this section, we will go through the concepts of assignment operator, shallow copy, deep copy and copy constructors in C++. Though they all may seem to be simply making copies of some object, how they do it varies and carries some nuances. Assignm...
Let’s say we wish to take the user’s name as input and store it somewhere in C++. Now, the name can be of any size and we don’t exactly know the length of input string apriori. How do you then declare a data structure with variable size? int size; st...
Part - 1 We have seen variable types so far which can hold integers (int), floating point numbers (float) and so on. So, what if we wanted a special variable or just some variable that could hold the address of a variable? Such a variable is called a...
References much like pointers allow us to pass objects to functions without making a copy of the object. This helps save memory and improves performance, especially when working with large objects (like containers or complex data structures). But unl...
For normal functions, the definition and declaration are written in some .hpp and .cpp files respectively and whenever in code we need to call the function, we import the header file and call the function in our source code. When we call the function...
When we declare a variable in C++ with const, it implies that its value will not change throughout the program. If we try to assign a new value to the variable, it will generate an error. const float PI = 3.1415; //type const float const Function A...
