WebbIn class-based, object-oriented programming, a constructor (abbreviation: ctor) is a special type of function called to create an object.It prepares the new object for use, often accepting arguments that the constructor uses to set required member variables.. A constructor resembles an instance method, but it differs from a method in that it has no … WebbThe best way to declare a string literal in your code is to use array notation, like this: char string [] = "I am some sort of interesting string.\n"; This type of declaration is 100 percent okey-doke. The compiler allocates proper storage for the string, including the null character at the end, and it assigns it to the array string. Nifty keen.
