Question
Can someone modify this code for me to do the following? Replace the structs in your solution to the program with classes. Replace the array of class objects with a vector of class objects Modify the program to copy the contents of a file into the vector of class objects Modify the program to copy the vector of class objects to a file.

Explanation / Answer
Here is the script. Please make sure to include algorithm header file to make sure that the find function of the vector is working. This would work great :)
