You need to know about stringstream first. We use cin stream to take input from the user, similarly, we first initialize the stringstream's object and take the input in it using "<<" operator which allows it to read a string as a stream of words. The most commonly used stringstream ...
Use the copy() Function to Parse String by a Single Whitespace Delimiter copy() is a <algorithm> library function, which can iterate through the specified range of elements and copy them to the destination range. At first, we initialize a istringstream variable with the text argument. After ...

Well, in that case I suggest you adopt Pavel A's suggestion. Do you mean I have to assign my variable to unsigned int variable and then I have to pass it to the function? Pavel A suggested that you pass the member of the union that is an unsigned int. Changes to the value o...
Theshared_ptrtype is a smart pointer in the C++ standard library that is designed for scenarios in which more than one owner needs to manage the lifetime of an object. After you initialize ashared_ptryou can copy it, pass it by value in function arguments, and assign it to othershared_...
It is always good practice to initialize the state of the class before it is used, because there is no automatic guarantee of the values held in member data upon construction. The best place to do this initialization is in the class constructor, and for intrinsic data types, it is good pr...
