What are map operations in C++?

Can you explain what map operations are in C++?

Sure! In C++, a map is a collection of key-value pairs, where each key is unique. Map operations include insertion, deletion, and searching for elements.

How do I insert a new element into a map?

You can insert a new element using the insert function or the subscript operator. For example: myMap[key] = value;.

What happens if I try to insert a duplicate key?

If you insert a duplicate key, the existing value associated with that key will be updated with the new value.

Can you show me an example of using a map in C++?

Certainly! Here's a simple example:

#include <iostream>
#include <map>

int main() {
    std::map<int, std::string> myMap;
    myMap[1] = "One";
    myMap[2] = "Two";
    std::cout << myMap[1]; // Outputs: One
    return 0;
}
