Utility Functions in C++ pair and tuple The C++ programming language Standard Template Library (STL) provides utility data type methods like pair and tuple to handle and manage groups or collections of data elements. The pair and tuple system-defined utility data type methods in C++ are built-in features of the utility and tuple header files,…
Algorithms in C++ sort, find, reverse The built-in Standard Template Library (STL) collection in the C++ programming language provides C++ users with a rich collection of multiple algorithms. These built-in supported algorithms are designed to implement multiple separate system tasks or operations on container data types such as vectors, lists, sets, etc., and other iterator…
Iterators in C++ Container iterators in the C++ programming language are user-defined program data type objects that provide a variety of methods and options for managing access to and traversing elements of C++ container data types, such as vectors, lists, sets, maps, and so on. These pointers function similarly to data objects, but are more…
Introduction to C++ Containers Vector, List, Set, Map Data structures in the C++ programming language provide its users with a variety of rich set data types, which are added to C++ through built-in Standard Template Library (STL) containers called containers. These help C++ users store and manipulate collections of data in a proper order. These…
File Operations Using C++ File Streams fstream, ifstream, ofstream In the C++ programming language, file handling data read and write operations are handled using the fstream class library. It provides classes for reading files from existing secondary storage locations and for creating and writing data and information to those files. The most commonly used file…
File Pointers and Stream Manipulation in C++ User-defined file pointers and stream manipulation functions in the C++ programming language provide C++ users with greater control over file input and output operations, particularly when C++ users need to navigate, modify, or format data within existing text and binary files. File pointers are used in C++ program…
Reading and Writing to Files in C++ The C++ programming language allows its users to handle and manage text and binary files through its built-in fstream class library. This includes several classes for reading and writing user-defined C++ program files. Popular file handling operations include the main file classes ifstream (input file stream), ofstream (output…
Custom exceptions in c++ In the C++ programming language, custom exceptions are implemented in C++ programs to handle or manage runtime custom user-defined error exception messages at program execution time without crashing or damaging the user-created C++ program. As we have previously discussed, several standard exception classes in C++ (such as std::runtime_error and std::invalid_argument) exist.…
Standard Exceptions in C++ The built-in Standard Class Library in the C++ programming language provides its users with a hierarchy or structure library of multiple exception classes for pre-defined C++ programs. All of these are automatically derived from the base or parent class std::exception in C++ programming. These Standard Class Library exceptions are used to…
Interfaces in C++ In the C++ programming language, class interfaces are a design pattern for user-defined classes that define a set of pure virtual functions without providing any implementation in a base class. A custom interface defined in a class enforces a specific behavior contract, requiring existing classes to implement certain custom class function methods…
