A vector can store multiple data values, similar to an array, but they can only store object references and not basic data types. Storing object references means they point to the object that contains the data rather than directly storing the data. Unlike arrays, vectors do not require size initialization. They can dynamically resize based … Read more
Before learning C++, we implemented sequential lists and linked lists using C, which are the foundation of learning data structures. It’s always good to have early exposure. After learning C++, we implemented them twice again, once using classes and once using template classes. Now, let’s move on to the first topic of C++—classes. Classes When … Read more
cin is an object used to get input from the user, but it does not allow multi-line input. To accept multi-line input, we use the getline() function. The getline() function is a predefined function defined in the <string.h> header file, used to accept a line or a string from the input stream until a delimiter … Read more
In C++ programming, we use the iostream standard library, which provides the methods cin and cout for reading from input and writing to output. To read from and write to files, we use a standard C++ library called fstream. Let’s take a look at the data types defined in the fstream library: Data Type Description … Read more
C++ comments are statements that are not executed by the compiler. Comments in C++ programming can be used to explain code, variables, methods, or classes. With comments, you can also hide program code. There are two types of comments in C++: Single-line comments Multi-line comments 👇Click to receive👇 👉C Language Knowledge Resource Collection C++ Single-line … Read more
Namespaces in C++ are used to organize an excessive number of classes for easier handling of applications. To access classes within a namespace, we need to use namespacename::classname. We can also use the using keyword, so we don’t have to keep using the full name. In C++, the global namespace is the root namespace. global::std … Read more
In C/C++ courses and projects, the application of functions is crucial. Here, we have gathered and organized some commonly used functions in C/C++. We hope you can apply them frequently to gain proficiency. 1. Character Processing Functions This category of functions is used for processing individual characters, including character type testing and case conversion. Header … Read more

The Father of C++ Discusses Five Misconceptions About C++ These five misconceptions have prevailed in C++ for many years: 1. “To understand C++, you must first learn C.” 2. “C++ is an object-oriented language.” 3. “Garbage collection is essential for reliable software.” 4. “To improve efficiency, you must write low-level code.” 5. “C++ is only … Read more
