Chapter 12: Problem 11

What arguments do you pass to a file stream object’s read member function?

Short Answer

Expert verified

Answer: The read member function requires two arguments: 'buffer' and 'size'. 'buffer' is a pointer to an array of characters where the read data will be stored, while 'size' is an integer value representing the number of characters to read from the file.

Step by step solution

Understand the file stream object's read member function

A file stream object's read member function is used to read data from a file. This function belongs to the ifstream (input file stream) class and is typically used for reading from binary files.

Know the syntax of the read member function

The syntax for the read member function is as follows: file_stream_object.read(buffer, size); Here, `file_stream_object` is an ifstream object, `buffer` is a pointer to an array of characters where the read data will be stored, and `size` is the number of characters to read from the file.

Understand the arguments to be passed to the read member function

There are two arguments that need to be passed to the read member function: 1. buffer - A pointer to an array of characters. The read member function will store the data read from the file into this buffer. The buffer can be defined as an array of characters or as a pointer to char. Example: char buffer[100]; 2. size - The number of characters to read from the file. This is usually specified as an integer value. For example, if you want to read 50 characters from the file, you can use the `read` member function as follows: ifstream file("example.bin", ios::binary); char buffer[100]; file.read(buffer, 50);
