Discussion Questons

Please respond to all of the following prompts:

• How are input and output accomplished in C++?
• How do cin and cout relate to ostream and istream?

Lab Activity

1. Write a C++ program per the requirements in the problem. This activity will focus on the use of files.

• To complete this activity, please refer to: Programming Problems 14.1.

Programming Problems 14.1

1. Write a program that combines the processing of programs prb14-1.cpp and 14- 2.cpp. Thus, the program should create the parts inventory file by obtaining the data from the user. After creating the file, the program should then search through the file and display those records whose quantity on hand multiplied by price exceeds 3000.00. Declare the file as an f stream object so you can perform both input and output on the file.

2. A small business wants to create a file to store its customer information. Each record in the file is to contain the following data: customer ID number (an inte¬ger 01-54 first name, last name, city, zip code, and account balance. Write a pro¬gram to create such a customer file. Set up the file as a sequential text file with space-separated fields.

3. Write a program that displays the file of Programming Problem 2 in column form with appropriate column headings.

• To complete this activity, please refer to: Programming Problems 14.3.

Programming Problems 14.3

1. Write a program that asks the user to enter the name of a file. The program should display the number of characters in the file.

2. Write a program that asks the user to enter the name of a text file. The program should display on the monitor the contents of the file in reverse order, that is from the last character to the first.

3. Write a program that asks the user to enter the name of a text file. The program should display on the monitor the middle character in the file if there is an odd number of characters in the file. If there is an even number of characters in the file, the program should display the middle two characters

4. Write a program that asks the user to enter the name of a text file and a positive integer, n. The program should display on the monitor the n-th character in the file. If n exceeds the number of characters in the file, the program should display an error message.

Submission Instructions: ***NOTE: For all C++ assignments, include a screenshot of your C++ program in the Visual Studio window along with the output showing or submit the actual program file. Do this for all labs.
