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.

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

while (it != contacts.end()) {

name= it->first;

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.
