SET - ERASE() METHOD

erase() method remove an element from the Set by its name/value.

Let us say, we have a Set that contains three names, Mohan, Kriti and Salim. And we want to remove Kriti from the Set.

It can be done with the erase() Function

Example :

#include <iostream>
#include <set>

using namespace std;

int main() {

    set<string> x = {"Mohan", "Kriti", "Salim"};
    x.erase("Kriti");

    for (string data : x) {  
        cout << data << endl;  
    }
    
    return 0;    
}

Output :

Mohan
Salim

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 remove() function that searches for the name Kriti and removes it from the Set.

x.remove("Kriti");

And we get the below output,

Output :

Mohan
Salim
