StringStream C++

In this challenge, we work with string streams. stringstream is a stream class to operate on strings. It implements input/output operations on memory (string) based streams. stringstream can be helpful in different type of parsing. The following operators/functions are commonly used here Operator >> Extracts formatted data. Operator << Inserts formatted data. Method str() Gets the contents of underlying string device object. Method str(string) Sets the contents of underl

Strings C++

C++ provides a nice alternative data type to manipulate strings, and the data type is conveniently called string. Some of its widely used features are the following: Declaration: string a = "abc"; Size: int len = a.size(); Concatenate two strings: string a = "abc"; string b = "def"; string c = a + b; // c = "abcdef". Accessing i th element: string s = "abc"; char c0 = s[0]; // c0 = 'a' char c1 = s[1]; // c1 = 'b'

Structs C++

struct is a way to combine multiple fields to represent a composite data structure, which further lays the foundation for Object Oriented Programming. For example, we can store details related to a student in a struct consisting of his age (int), first_name (string), last_name (string) and standard (int). struct can be represented as struct NewType { type1 value1; type2 value2; . . . typeN valueN; }; You have to create a struct, named Student, representing

Class C++

Classes in C++ are user defined types declared with keyword class that has data and functions . Although classes and structures have the same type of functionality, there are some basic differences. The data members of a class are private by default and the members of a structure are public by default. Along with storing multiple data in a common block, it also assigns some functions (known as methods) to manipulate/access them. It serves as the building block of Object Oriented Programming.

Classes and Objects C++

A class defines a blueprint for an object. We use the same syntax to declare objects of a class as we use to declare variables of other basic types. For example: Box box1; // Declares variable box1 of type Box Box box2; // Declare variable box2 of type Box Kristen is a contender for valedictorian of her high school. She wants to know how many students (if any) have scored higher than her in the 5 exams given during this semester. Create a class named Student with the
