In multi-threaded programming, synchronization refers to the coordination of thread execution to ensure that threads access shared resources in a safe and predictable manner. One common way to achieve synchronization in C++ is through the use of locks, which provide mutual exclusion and prevent multiple threads from accessing shared resources simultaneously. C++ provides several types … Read more
In C++, you can create and manage threads using the standard library’s `thread` class, which is defined in the “ header file. Here’s an example of how to create a thread: c++ #include #include void threadFunction() { std::cout << “Hello from a thread!\n”; } int main() { std::thread t(threadFunction); // create a new thread and … Read more
Sockets are a low-level networking API that allows programs to communicate over networks. In C++, sockets are typically used to implement client-server architectures, where a server process listens for incoming connections from client processes, and clients connect to the server to exchange data. Creating and binding sockets: To create a socket in C++, you typically … Read more
Synchronization and locks are essential concepts in concurrent programming, which involves multiple threads of execution accessing shared resources concurrently. C++ provides several synchronization primitives, such as mutexes, condition variables, and semaphores, to manage access to shared resources and ensure thread safety. Mutexes: A mutex, short for “mutual exclusion,” is a synchronization primitive that provides mutual … Read more
Function objects, also known as functors, are a powerful feature of C++ that allow you to define custom functions that can be used as arguments to other functions, such as algorithms. Function objects are implemented as classes or structs that overload the function call operator `operator()`, allowing them to be called like regular functions. In … Read more
C++ provides a rich set of algorithms that can be used to perform a variety of operations on containers, such as sorting, searching, transforming, and more. These algorithms are defined in the “ header and can be used with many standard containers, such as vectors, arrays, and lists. Here are some examples of how to … Read more
Iterators are objects used to access the elements of a container in C++. They provide a way to traverse a container’s elements, and can be used with many standard library algorithms to manipulate the container’s data. In C++, there are several types of iterators, each with different capabilities and limitations. Here are some examples of … Read more
In C++, stream classes are used for input and output operations. There are four main stream classes: `istream`, `ostream`, `ifstream`, and `ofstream`. – `istream` is an abstract base class that represents an input stream. It provides a set of functions for reading data from a stream, such as `get()`, `getline()`, and `>>`. – `ostream` is … Read more
In C++, files can be opened and read or written in two different modes: text mode and binary mode. In text mode, the data in the file is treated as text, while in binary mode, the data is treated as a sequence of bytes. In text mode, C++ automatically performs newline conversion, which means that … Read more
In C++, new files can be created and opened for reading or writing using the standard input/output library. The `ofstream` class is used to create and write to files, while `ifstream` class is used to read from files. The `fstream` class can be used to handle both reading and writing. To create a file in … Read more
