Question

A contact list is a place where you can store a specific contact with other associated information such as a phone number, email address, birthday, etc. Write a program that first takes as input an integer N that represents the number of word pairs in the list to follow.Word pairs consist of a name and a phone number (both strings). That list is followed by a name, and your program should output the phone number associated with that name.

Answer 1

Answer:

C++.

Explanation:

Code snippet.

#include <map>

#include <iterator>

cin<<N;

cout<<endl;

/////////////////////////////////////////////////

map<string, string> contacts;

string name, number;

for (int i = 0; i < N; i++) {

   cin<<name;

   cin<<number;

   cout<<endl;

   contacts.insert(pair<string, string> (name, number));

}

/////////////////////////////////////////////////////////////////////

map<string, string>::iterator it = contacts.begin();

while (it != contacts.end())  {

   name= it->first;

   number = it->second;

   cout<<word<<" : "<< count<<endl;

   it++;

}

I have used a C++ data structure or collection called Maps for the solution to the question.

Maps is part of STL in C++. It stores key value pairs as an element. And is perfect for the task at hand.
