List of C++ topics

Inheritance in C++

Inheritance in C++ allows us to define a class in terms of another class, which makes it easier to create and maintain an application. This provides an opportunity to reuse the code functionality. Single, multiple, hierarchical, multilevel, multipath and hybrid inheritance is supported in C++

C++

Namespace in C++

Namespaces in C++ allow us to group named entities that otherwise would have global scope into narrower scopes, giving them namespace scope. This allows organizing the elements of programs into different logical scopes referred to by names.

C++

Unique_ptr in C++

A unique_ptr is like a normal pointer, except the fact that it "owns" the object to which it points, as mentioned above. The word "unique" in the title refers to the fact that at a time, only one unique_ptr can point to a given object and the object is destroyed when the pointer is destroyed.

C++

Program Flow control in C++

The flow of control jumps from one part of the program to another, depending on calculations performed in the program. Program statements that cause such jumps are called control statements. We have covered for, while, do while loop, if else, switch, break, continue, goto and functions.

C++

Friend Function in C++

C++ allows a mechanism, in which a non-member function has access permission to the private members of the class. This can be done by declaring a non-member function friend to the class whose private data is to be accessed. The friend is a keyword.

C++

Operator Overloading in C++

Operator overloading is an important concept in C++. It is a type of polymorphism in which an operator is overloaded to give user defined meaning to it. Overloaded operator is used to perform operation on user-defined data type. We give examples of unary ++, bitwise + and arithmetic + operators

C++

Threads in C++

Threads are generally referred to as lightweight processes and executes different parts of a program and shares memory, file descriptors and system resources. We explore multithreading creation of threads with free, member function, functor object, lambda expression, race condition with mutex

C++

Function Overriding in C++

Function overriding (compile time polymorphism) is a feature in C++ that allows us to have a function in child class which is already present in the parent class. A child class inherits the data members and member functions of parent class and to override functionality, function overriding is used

C++

Function Overloading in C++

Function overloading is a feature in C++ where two or more functions can have the same name but different parameters. This is used in situations when a class B is inherits from class A and a particular behaviour of the class B needs to be modified.

C++

for loop in C++

For loop has three components: initialization Statement, test Expression and update Statement. We have explored for loop in C++ and presented examples and compared it with while loop.

Software Engineering

Functions in C

A function in C is a set of statements that take inputs, do some specific computation and produces output. The idea is to put some commonly or repeatedly done task together and make a function, so that instead of writing the same code again and again for different inputs, we can call the function.

Software Engineering

An in-depth look into Recursion in C

Recursion is a coding technique/ design in which a function calls itself directly or indirectly and the corresponding function is called as recursive function. Using this many problems can be solved easily with less time. C, C++, Java, Python, Go and others support Recursion except Fortan 77

Software Engineering

malloc vs calloc vs realloc

We take a deep look into the 3 dynamic memory allocation techniques in C/ C++ namely malloc, calloc and realloc and explore the difference. malloc stand for memory allocations, calloc for contiguous allocation and realloc for re-allocation.

eigen

What is Eigen C++ Library?

Eigen is an efficient open-source C++ library for linear algebra, matrix and vector operations, geometrical transformations, numerical solvers and related algorithms. It has been developed by two great developers namely Benoit Jacob and Gael Guennebaud. It has support for compilers like GCC

C++

Most commonly used utilities in Standard Template Library in C++

This is an overview of the most commonly used utilities in Standard Template Library in C++. We have covered Iterator, Vector, Stack, Queue, Priority Queue, Map, Set and Pair utilities.

C++

Standard Template Library in C++

Standard Template Library in C++ is a pre-defined generic implementation of most widely used data structures and algorithms. By generic implementation it means that there is a single implementation of various Classes and Functions which works with multiple datatypes by the use of templates.

C++

Object Slicing in C++

Object slicing is a situation in `C++` when a derived class object is assigned to a base class object, the additional attributes of a derived class object are sliced off (not considered) to form the base class object. There are 3 key concepts involved.
