Below mentioned are some of the key benefits of using constructors while coding: Initialization:Constructors provide a way to initialize the data members of an object when created. A constructor ensures that the object is valid from the beginning and eliminates the need for separate initialization ...
The above code defines a functionprintIntthat takes a void pointer num as a parameter and casts it to an integer pointer using thestatic_cast operator. The function then prints the value of the integer pointed to by the casted pointer. In the main function, an integer variable x is defined...
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 would like to clarify that no it's not: NULL - cppreference...
2. C++ inlining is resolved at compile time. Which means if you change the code of the inlined function, you would need to recompile all the code using it to make sure it will be updated 3. When used in a header, it makes your header file larger with information which users don’t...
