The Standard Template Library (STL) in C++ provides several containers to store and manage data. One of the most commonly used containers is the list. A list is a linear collection of elements that can grow or shrink dynamically, and elements can be inserted or removed from the list in constant time. In this article, […]
C++ Standard Library provides a simple yet powerful tool called pair to store two values of different data types as a single unit. The pair is defined in the <utility> header file and can be used to store any two values, including values of built-in data types and user-defined data types. Creating a Pair A […]
The C++ Standard Library provides a rich set of mathematical functions and algorithms that can be used to perform various mathematical operations. The functions and algorithms are defined in the <cmath> header file, which is a part of the C++ Standard Library. Trigonometric Functions The C++ Standard Library provides a set of trigonometric functions for […]
Vectors are dynamic arrays in C++ and are part of the Standard Template Library (STL). They are similar to arrays, but the size of a vector can be changed during runtime, making them more flexible than arrays. Vectors also provide many built-in functions to perform various operations, making them easier to use. Creating a Vector […]
In C++, virtual functions are member functions of a class that are declared with the keyword “virtual”. These functions are intended to be overridden by derived classes. Virtual functions are used to achieve runtime polymorphism, which is the ability of a function to behave differently based on the type of object it is called on. […]
A friend function in C++ is a non-member function that is given access to the private and protected members of a class. The function is declared using the keyword “friend” inside the class, but it is defined outside the class. Friend functions are not in the scope of the class and are not considered a […]
Enumeration, or “enum” for short, is a user-defined data type in C++ that consists of a set of named values. Enums are used to represent a group of related values and can be useful in situations where a set of named constants is needed. Enums are similar to constants, but they are more powerful and […]
C++, like many programming languages, allows for the conversion of one data type to another, known as type conversion. This can be done either implicitly or explicitly. It is important to understand the different types of conversions and their implications in order to write efficient and error-free code. Implicit Type Conversion Implicit type conversion, also […]
In C++, scope refers to the region of the program where a variable or a function can be accessed. Understanding scope is crucial in C++ programming as it determines the visibility and lifetime of variables and functions, and can affect the behavior of the program. In this article, we will take a detailed look at […]
C++ namespaces are a feature of the C++ programming language that enables the creation of separate and distinct named spaces for identifiers (variables, functions, etc.). This allows for the organization of code and the avoidance of naming conflicts. In this article, we will take a detailed look at C++ namespaces and how they can be […]
