PROBLEM STATEMENT

You are working as a software engineer in a Financial Company, Stockers.

Stockers is a leading MNC that specializes in analyzing a companys shares and consulting

investors/traders.

Till today the company is working manually and wants to be digital. As a Software Engineer, you

are required to code user stories and create the first version of the application.

The Application will accept the no of companies N, that the user wants to store records of.

a) Users will enter the share price(double format) of N companies.

b) Users will enter a boolean value(TRUE, FALSE) of each company, to keep track of the

companys share price compared to yesterday.

The user will enter value through the console.

Insight: If today the share price of the company is greater than that of yesterday then the user

will input TRUE, else the user will input FALSE. In the given test cases true, false values are

entered randomly. You can also input values TRUE/FALSE on your own.

1. Display the companies stock prices in ascending order

2. Display the companies stock prices in descending order

3. Display the total no of companies for which stock prices rose today

4. Display the total no of companies for which stock prices declined today
