Master C++ constructors with this comprehensive guide for beginners. Learn to initialize objects, set default values, and perform complex initialization tasks.
Exception handling in C++ is a mechanism that allows a program to handle errors or exceptional situations during runtime by using try, catch, and throw statements.
A Constructor in C++ is a special member function having the same name as that of its class, which is used to initialize some valid values to an object’s data members. It is executed automatically whenever an object of a class is created. The only restriction that applies to the construc...
Constructor has the same name as the class name. 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. ...
While Loop: The while loop repeatedly executes a block of code as long as a specified condition is true. Do-While Loop: The do-while loop is similar to the while loop but with one crucial difference: the condition is checked after the loop body is executed. This guarantees that the loop...

(or .cpp) files known to your build system, along with their corresponding .h files. If your project has a .h file with no corresponding .cc file, IWYU will ignore it unless you use the--check_alsoswitch to add it for analysis together with a .cc file. It is possible to run IWYU...
It is a special type of class. It is basically created for linked list and tree based implementation in C++. If a class contains the data member as pointer to object of similar class, then it is called a self-referential class.
