Question
c++ programming
There is a file of a few movies that contains the following data:
Date of release
Movie name
Production cost
Gross profit
Your assignment is: for each movie,
1. Without changing the data, read in the Date of release,
the Movie name, the Production cost and the Gross profit
for all of the movies and put the information into an
array of structs (or classes).
2. Sort the array of movies by Movie Name alphabetically
3. Print the array of movies with a heading.
The fields should be printed in the following order:
Movie Name, Release Date, Production cost and Gross profit
4. Sort the array of movies by Percent Profit (Gross profit/Production Cost)
3. Print the array of movies with a heading.
The fields should be printed in the following order:
Movie Name, Production cost, Release Date and Percent Profit
