Chapter 17, Problem 47RQE

Explanation of Solution

Set:

In C++, a container which is used to store the unique values is referred as “set”.

• A “set” container can be implemented using the STL (Standard Template Library) class “set” template. The importance of set are discussed as follow as:
  • “set” elements must be “unique”, which means no two elements in a “set” can be the same values.
  • “set” elements are automatically sorted in ascending order.
• A “set” can contain duplicate values, if a value is inserted more than once in a “set”, then it will be added only one time in the “set” container.
• Hence, there are no duplicates in the “set” container.

Example:

Consider the following code

//Include the required header files

#include <iostream>

#include <string>

#include <set>

#include <iterator>

using namespace std;

//main function

int main()

{

//declare the set object

set<int> value ;

//insert the values in the set

value...
