1. Reading Data from Files Input data read from the keyboard and output data written to the screen are temporary and will be lost when the program ends. In this lab component, you will learn to read from a file. The reading from/writing to a file in a program is usually referred to as file /O (Input/Output).

Before we get started writing the program, create a text file called act9A.txt that will contain the following integer values, each on a separate line as follows: 236 19 917 83 148 385 74 Working with files consists of the following four steps: a. Declare the stream variables (don't forget to include
