How to create a Set of Strings in C++ ?

Answer

To create a set of strings in C++, you can use the std::set container from the Standard Template Library (STL).

✐ Examples

1 Create a Set of Strings using std::set

In this example,

We include the <set> header for the std::set container.
We declare a std::set named string_set to store strings.
We use the insert member function to add strings to the set.

C++ Program

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

int main() {
    std::set<std::string> string_set;
    string_set.insert("Apple");
    string_set.insert("Banana");
    string_set.insert("Orange");
    string_set.insert("Grapes");

    for (const auto& str : string_set) {
        std::cout << str << std::endl;
    }

    return 0;
}

Output

Apple
Banana
Grapes
Orange
