Chapter 12: Problem 59

True or False The getline member function can be used to read text that contains whitespaces.

Short Answer

Expert verified
Short Answer: Yes, the getline member function can be used to read text that contains whitespaces. Unlike other input functions such as 'cin', getline continues to read characters, including whitespaces, until it encounters a specified delimiter (usually a newline character). This makes it useful for working with text that has whitespaces.

Step by step solution

01

Get familiar with what getline does

The getline member function is a function that reads a line of text from an input stream and stores it in a string. It has the ability to read characters including whitespaces until it encounters a specified delimiter (usually a newline character). Phase 2: Show the step-by-step solution
02

Explain the usefulness of getline

Unlike many other input functions such as 'cin' that stop reading when they encounter whitespace, getline continues to read characters until reaching the delimiter or until the given maximum number of characters are read (if specified). This makes getline particularly useful when working with text that has whitespaces.
03

Provide an example to demonstrate getline

Let's consider an example where we want to read a line of text containing whitespaces. #include #include int main() { std::string line; std::getline(std::cin, line); std::cout << "The line you entered is: " << line << std::endl; return 0; } In this code, the getline function reads the input stream (std::cin) and stores it in the 'line' string variable. The input can include whitespaces, and they will not be ignored. The delimiter in this case is the newline character, which is the default delimiter for getline.
04

Conclusion

The statement is true: The getline member function can be used to read text that contains whitespaces.

How do you read the contents of a text file that contains whitespace characters as part of its data?

Write code that opens the file data.txt for both input and output, but first determines if the file exists. If the file does not exist, the code should create it, then open it for both input and output.
