Mastering C++: A Comprehensive Quiz Based on 'Thinking in C++'

According to the text, how is 'goto' used in C++?

1. To initialize variables

2. To call functions

3. To break out of nested loops

4. For creating infinite loops

The correct answer is: To break out of nested loops

The goto statement in C++ is used to transfer control to a specific labeled statement within the same function. Option A is incorrect as initialization of variables happens through the assignment of a value to them. Option B is incorrect as function calls are made using the function name followed by parameters within parentheses. Option D is incorrect as infinite loops can be created using a variety of statements, not just goto. Essentially, goto statements in C++ are used for transferring control within a function based on certain conditions, making option C the correct answer.
