C++ Math sin() Function
In this post, I am going to explain the C++ Math sin() Function for mathematical calculation. The function is used to find the sine of an angle given in radian. Syntax Of sin(): Consider a radian ‘x’. The syntax would…
Creating a file In C with Opening and Closing
In this post, we are going to learn about how to Creating a file in C, Opening and Closing a file in C programming. This means we will learn about how to create a file in C. Let’s dive deep.…
File Handling in C
In this topic today I am going to teach about File Handling In C programming. What is a file? A file is an object which holds data, information or commands. Like many other programming languages, C also provides operations in…
C++ Math cos() function
In this post today I am going to discuss C++ Math cos() functions. The function is used to determine the cosine of an angle given in terms of a radian. Syntax Of cos() function: Consider a radian ‘x’. The syntax…
Hyperbolic Math Functions In C++
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…
Exponential Math Functions In C++
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…
Trigonometric Math Functions In C++
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…
Friend function in C++
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…
Enum In C++
Enum in C++ is a data type that holds a fixed collection of constants. It may be used to represent days of the week (SUNDAY, MONDAY, TUESDAY, WEDNESDAY, WEDNESDAY, THURSDAY, FRIDAY, and SATURDAY) as well as directions (NORTH, SOUTH, EAST,…
Structs In C++
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…
Static Keyword In C++
Static Keyword In C++ is also called a modifier that refers to the type rather than the instance. As a result, access to the static members does not need the use of an instance. Field, method, constructor, class, properties, operator,…
What is this Pointer In C++?
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…
What is Destructor In C++
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:
Copy Constructor In C++
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…
What is Constructor In C++
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…
Object and Class In C++
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…
free() Function vs delete Operator in C++
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…
What are C++ Object Oriented Programming(OOPs) Concepts?
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…
malloc() Function vs new Operator in C++
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…
What is Memory Management In C++?
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…
