print set c++

To print a set in C++, you can follow these steps:

Step 1: Include the necessary header file.

#include <iostream>
#include <set>

Step 2: Define the main function.

int main() {
    // code goes here
    return 0;
}

Step 3: Create a set and add elements to it.

std::set<int> mySet;
mySet.insert(10);
mySet.insert(20);
mySet.insert(30);

Step 4: Iterate over the set and print its elements.

for (auto element : mySet) {
    std::cout << element << " ";
}

Step 5: End the program.

return 0;

This code will create a set of integers, add some elements to it, and then iterate over the set to print each element. The output will be the elements of the set separated by spaces.
