File Handling. In C, you can create, open, read, and write to files by declaring a pointer of type FILE, and use the fopen () function: FILE *fptr. fptr = fopen (filename, mode); FILE is basically a data type, and we need to create a pointer variable to work with it ( fptr ). For now, this line is not important. Syntax. do {. // code block to be executed. } while (condition); The example below uses a do/while loop. The loop will always be executed at least once, even if the condition is false, because the code block is executed before the condition is tested: C++ Classes and Objects. Class in C++ is the building block that leads to Object-Oriented programming. It is a user-defined data type, which holds its own data members and member functions, which can be accessed and used by creating an instance of that class. A C++ class is like a blueprint for an object. For Example: Consider the … When a variable is created in C, a memory address is assigned to the variable. The memory address is the location of where the variable is stored on the computer. When we assign a value to the variable, it is stored in this memory address. To access it, use the reference operator ( & ), and the result represents where the variable is stored: Define C++ Objects. A class provides the blueprints for objects, so basically an object is created from a class. We declare objects of a class with exactly the same sort of declaration that we declare variables of basic types. Following statements declare two objects of class Box −.
