Chapter 13: Problem 10

Write a statement that defines a file stream object named pets. The object will be used for file input.

Short Answer

Expert verified

Answer: The file stream object declared in the code is named "pets" and it is initialized as an input file stream (std::ifstream) with the file name "pets.txt".

Step by step solution

1. Include Necessary Headers

To use file stream objects, we need to include the header, which is a part of the C++ Standard Library. ```cpp #include #include ```

2. Declare and Initialize the File Stream Object

Declare a file stream object named "pets" and open it in input mode (ifstream stands for input file stream). It is important to mention the file name (e.g., "pets.txt") that we want to read data from. ```cpp std::ifstream pets("pets.txt"); ```

3. Check If the File is Open

It's good practice to check if the file was opened successfully. If not, display an error message and exit the program. ```cpp if (!pets.is_open()) { std::cerr << "Error: Unable to open the file." << std::endl; return 1; } ```

Complete Code

Here's the complete code for defining the file stream object named "pets" and using it for file input: ```cpp #include #include int main() { std::ifstream pets("pets.txt"); if (!pets.is_open()) { std::cerr << "Error: Unable to open the file." << std::endl; return 1; } // Code to read data from the file and perform necessary operations... pets.close(); return 0; } ```
