CENGAGE MINDTAP Opening Files and Performing File Input in C++ | Opening Files and Performing File Input Summary In this lab, you open a file and read input from that file in a prewritten C++ program. The program should read and print the names of flowers and whether they are grown in shade or sun. The data is stored in the input file named flowers.dat. Instructions 1. Ensure the source code file named Flowers.cpp is open in the code editor. 2. Declare the variables you will need. 3. Write the C++ statements that will open the input file flowers.dat for reading. 4. Write a while loop to read the input until EOF is reached. 5. In the body of the loop, print the name of each flower and where it can be grown (sun or shade). 6. Execute the program by clicking the Run button at the bottom of the screen.

|Opening Files and Performing File Input
Summary
In this lab, you open a file and read input from that file in a
prewritten C++ program. The program should read and print the
names of flowers and whether they are grown in shade or sun. The
data is stored in the input file named flowers.dat.
Instructions
1. Ensure the source code file named Flowers.cpp is open in the
code editor.
2. Declare the variables you will need.
3. Write the C++ statements that will open the input file
flowers.dat for reading.
4. Write a while loop to read the input until EOF is reached.
5. In the body of the loop, print the name of each flower and
where it can be grown (sun or shade).
6. Execute the program by clicking the Run button at the bottom
of the screen.
