Phone interview with a senior developer.

A programming question was asked and answered (implemented) via a web portal, which the interviewer could see directly.

The interviewer was very friendly; however, I had some difficulty understanding the conversation due to the phone connection.

This is a C++ question.

Implement a StockMarket class in C++ that has the following two functions:

cpp class StockMarket { public: void addTrade(string stockName, int share); // This function tracks the number of shares transacted for a stock by adding the trade information.

void printTop(int numberOfStock);
// This function prints the top `numberOfStock` stocks that have the highest number of transacted shares.

};

Here is a sample calling sequence that uses the above class:

cpp StockMarket stockMarket; stockMarket.addTrade("GOOGLE", 50); stockMarket.addTrade("APPLE", 150); stockMarket.addTrade("GOOGLE", 100); stockMarket.addTrade("MSFT", 250); stockMarket.addTrade("GOOGLE", 200);

stockMarket.printTop(2);

Expected output:

GOOGLE 350 MSFT 250
