We can create a constructor for the Car class that takes arguments for each of these data members and initializes them when a Car object is created. Here’s a basic C++ constructor example: #include <iostream> class MyClass { public: MyClass() { std::cout << "Constructor called!" <<...
The feature I’m most excited about isstd::generator. This brings some long-awaited standard library support for coroutines. A little example fromthe paper: Copy std::generator<int>fib(){autoa =0, b =1;while(true) {co_yieldstd::exchange(a, std::exchange(b, a + b)); } }intanswe...
In C++, the “struct” is known as a structure that is a special member function within a struct that is used to initialize its member variables.
A void pointer, also known as a generic pointer, is a pointer that is not associated with any specific data type, making it suitable for pointing to any type of data. In other words, avoid pointercan point to an integer, a character, a string, or any other data type. This flexibility...
std::cout << "Before calling friend member function:" << std::endl; obj.display(); FriendClass fc; fc.friendMemberFunction(obj); std::cout << "After calling friend member function:" << std::endl; obj.display(); return 0;} Output: In this example, ‘FriendClass‘ is another class...

Program without using "using namespace std" and "std::" – Error will be occurred #include<iostream>intmain(){cout<<"Hi there, how are you?"<<endl;return0;} Output cout<<"Hi there, how are you?"<<endl; ^ main.cpp:6:2: note: suggested alternative: In file included from main....
NULL is 0(zero) i.e. integer constant zero with C-style typecast to void*, while nullptr is prvalue of type nullptr_t which is integer literal evaluates to zero. For those of you who believe that NULL is same i.e. (void*)0 in C & C++. I wo...
It is case sensitive. Constructor does not have return type. We can overload constructor, it means we can create more than one constructor of class. We can use default argument in constructor. It must be public type.Example of C++ Constructor...
string methods, or loading data in UTF-8 and converting to wide strings for Windows before modifying a string with the WinAPI. Let’s not even talk std::locale. RAD Studio provides powerful, useful classes for strings, conversions, file IO, streaming, JSON, REST, and anything else you ...
