How to add an Item to a Set in C++ - Step by Step Examples

How to add an Item to a Set in C++ ?

Answer

In C++, you can use the std::set container to represent a Set. To add an item to a Set, you can use the insert() method provided by the std::set class.

✐ Examples

1 Add Integer to Set

In this example,

We create a std::set named numbers containing some integer elements.
We use the insert() method of numbers to add a new integer element, such as 6, to the set.
Now, numbers contains the added element 6.

C++ Program

#include <iostream>
#include <set>

int main() {
    std::set<int> numbers = {1, 2, 3, 4, 5};
    numbers.insert(6);
    std::cout << "Numbers: { ";
    for (int num : numbers) {
        std::cout << num << " ";
    }
    std::cout << "}";
    return 0;
}

Output

Numbers: { 1 2 3 4 5 6 }

2 Add String to Set

In this example,

We create a std::set named fruits containing some string elements.
We use the insert() method of fruits to add a new string element, such as 'Orange', to the set.
Now, fruits contains the added element 'Orange'.

C++ Program

#include <iostream>
#include <set>
#include <string>

int main() {
    std::set<std::string> fruits = {"Apple", "Banana", "Cherry"};
    fruits.insert("Orange");
    std::cout << "Fruits: { ";
    for (const std::string& fruit : fruits) {
        std::cout << fruit << " ";
    }
    std::cout << "}";
    return 0;
}

Output

Fruits: { Apple Banana Cherry Orange }
