C++ map Searching and Deleting from a map Question

Introduction

Write a program that defines a map of integers and strings.

Search for an element by key using the map's.find() member function.

If the element is found, delete it.

Print out the map content.

You can use the following code structure: 

#include <iostream> 

int main() 
{ 

} 



#include <iostream> 
#include <map> 
#include <string> 

int main() 
{ 
     std::map<int, std::string> mymap = { {1, "First"}, {2, "Second"},   
     {3, "Third"}, {4, "Fourth"} }; 
    int findbykey = 2; 
    auto foundit = mymap.find(findbykey); 
    if (foundit != mymap.end()) 
    { 
        std::cout << "Key found." << '\n'; 
        std::cout << "Deleting the element..." << '\n'; 
        mymap.erase(foundit); 
    } 
    else 
    { 
        std::cout << "Key not found." << '\n'; 
    } 

    for (const auto& el : mymap) 
    { 
        std::cout << el.first << ' ' << el.second << '\n'; 
    } 
}
