In this post today I am going to explain different hyperbolic math functions in C++. Hyperbolic Math Functions: Method Description cosh(x) It computes the hyperbolic cosine of x. sinh(x) It computes the hyperbolic sine of x. tanh(x) It computes the…

In this post today I am going to explain exponential math functions in C++. Exponential Math Functions: Method Description exp(x) It computes the exponential e raised to the power x. frexp(value_type x,int* exp) It breaks a number into significand and…

In this post today I am going to explain trigonometric math functions in C++. C++ has several fundamental arithmetic functions, and the header file <math.h> is required to use them. Trignometric Functions: Method Description cos(x) It computes the cosine of…

In C++, if a function is declared as a friend function, the function can access a class’s protected and private data. The keyword friend informs the compiler that the supplied function is a friend function. The declaration of a friend…

Classes and structs are blueprints in C++ that are used to construct a class instance. Lightweight objects like rectangles, Colour, and Point are created using struct. In contrast to classes, structs in C++ are of the value type rather than…

In this post, we are going to learn about the use of this keyword and how to apply it? “this” is a keyword in C++ programming that refers to the current instance of the class. In C++, the “this” keyword…

A destructor is the complete opposite of a constructor, it destroys class objects. It can only be specified once per class. It is called automatically, just like Constructors. A Constructor is what a destructor is. It has to be named after the class. It is, however, preceded with a tilde symbol (~). Destructors in C++ are not allowed to contain arguments. Modifiers can’t be used on destructors, either. #Note C++ Constructor and Destructor Example: Let’s look at an example of a C++ constructor and destructor that is automatically invoked: Output:

The Copy Constructor In C++ an overloaded constructor is called a copy constructor used to declare and initialize an object from another object is called a Copy constructor. Copy Constructor is of two types: Default Copy constructor: The default copy constructor…

Constructor in C++ is a specific method in C++ that is called automatically when an object is created. In general, it’s used to set up the data members of a new object. In C++, the constructor name is the same…

The Class and the Object In C++, tackling real-world problems is a critical component. Because C++ is an object-oriented programming language, the program has been developed with C++ objects and classes. C++ Object: Before start discussing Object and Class In…

The difference between the free() function vs delete operator in C++ will be discussed in this topic. So let’s begin. free() Function: In C++, the free() method is used to dynamically de-allocate memory. It’s essentially a C library function that’s specified…

The main goal of C++ programming is to introduce the concept of Object-Oriented Programming and add some features to C programming. Many concepts such as inheritance, data binding, polymorphism, and many more are available in Object-Oriented Programming. True object-oriented programming…

The malloc function and new operator both are working for creating the memory blocks dynamically.  The declaration of the malloc() function and a new operator is different but we can use both in C++.  The malloc function comes under the…

To manage the computer memory and space to improve memory and system performance we need Memory Management In C++. Why is memory management required? Generally, everybody knows the array stores homogenous data and the size are fixed and can’t change…
