Consider each of the following code fragments below that could be part of a C++ program. Each fragment contains a call to a standard C/C++ library function. Answer each question in one of the following three ways: - If the code fragment contains a compile-time error, write the word error for the answer. - If the code fragment contains no compile-time errors and you can determine its output at compile-time, provide the fragment’s literal output. - If the code fragment contains no compile-time errors but you cannot determine its exact output at compile-time, provide one possible evaluation and write the word example for the answer and provide one possible literal output that the code fragment could produce. (a) std::cout << sqrt(4.5) << '\n'; (b) std::cout << sqrt(4.5, 3.1) << '\n'; (c) std::cout << rand(4) << '\n'; (d) double d = 16.0; std::cout << sqrt(d) << '\n';
