13.6.1. C++ Example

Try these first

1. 1.

   What class do you use to write to a binary file in C++?

   Hint

   Think about the file output stream.

2. 2.

   Which method do you call to write data to a file?

   Hint

   Look for the function related to outputting data.

3. 3.

   What is the purpose of the ios::binary mode in C++ file handling?

   • To read text data
   • To handle binary data
   • To create new files

   Hint

   Think about what type of data you are working with.

4. 4.

   True or False: The write() method requires the data to be in a string format.

   • True
   • False

   Hint

   Consider what types of variables can be written directly.

5. 5.

   Write a C++ program that reads integers from a binary file and outputs their sum.

   Hint

   Think about how you'd read integers just like you wrote them.

6. 6.

   Create a binary file with five random integers in C++, then read the integers and display them to the console.

   Hint

   Focus on random number generation and binary reading processes.
