Write c++ program in which collection contains G.I Joe\'s, which are you action

Question

Write c++ program in which collection contains G.I Joe's, which are you action figures, and the text file contains data about the collection of these toys. each line contains collection of one you with it's cost, year of purchase, condition and name of you. cost is floating point value and each data is separated by blanks.
1. Declare array with 75 components
2. print labeled listing of data in 4 columns
3.prompt user to enter year and then print listing of all data about all toys bought that year
4.prompt user for price

Explanation / Answer

Below is the code for the question. Since sample file is not given, tested with some test data on own assuming the file format to be with each of the like

name cost year condition

Also since space is being used as a delimiter, you would not be able to specify spaces in name or condition. Program would not work correctly if the field values have spaes. Also after prompting for price, question does not mention whether you want to list toys with same price or greater or lesser. So printing all greater than or equal to the specifid price.

In case there is any change in file format or query on price, please leave a comment with your requirements so that I can change the program accordingly. Please do rate the answer if it helped.
