SET - CLEAR() METHOD

The clear() Method is used to remove all the elements from the Set.

Example :

#include <iostream>
#include <set>

using namespace std;

int main() {

    set<string> x = {"Mohan", "Kriti", "Salim"};
        
    x.clear();
    for (string data : x)  
    {  
        cout << data << endl;  
    }
    
    return 0;    
}

Output :

So, in the above code we have created a Set and initialised to the variable x.

set<string> x = {"Mohan", "Kriti", "Salim"};

Below is how the values are positioned in the Set,

Next, we have used the clear() method that removes all the elements from the Set making the Set empty.

x.clear();

And we get an empty Set as output.
