Question

Write a statement that defines a file stream object named places. The object will be used for both output and input.

Short answer

Answer: To create a file stream object named 'places' for both input and output operations in C++, follow these steps: 1. Include the fstream library by adding the line `#include ` to your code. 2. Declare and initialize a file stream object named 'places' using the code: `std::fstream places;` 3. Open the 'places' object in both input and output mode with the statement: `places.open("filename.txt", std::ios::in | std::ios::out);` (Replace "filename.txt" with the actual file name you want to work on.)

Step-by-step solution

1. Include the fstream library in the C++ code

To create a file stream object, we need to include the fstream library in our C++ code. This can be done by adding the following line to the code: #include

2. Declare and initialize a file stream object named 'places'

Once the fstream library has been included, we can declare a file stream object named 'places' with both input and output modes. Use the following code to create the 'places' object: std::fstream places;

3. Open the 'places' object in both input and output mode

Finally, open the 'places' object with both input and output modes. When working with input/output mode, use the std::ios::in | std::ios::out flags in the open() statement. Here's the statement to open the 'places' object in both input and output mode: places.open("filename.txt", std::ios::in | std::ios::out); Keep in mind that "filename.txt" should be replaced by the actual file name you want to work on. With these steps, you've successfully defined a file stream object named 'places' to be used for both output and input operations.
