Study Notes

  • CSE 232 is an Introduction to Programming II course.

Exam Instructions

  • Don't start the exam until instructed.
  • Write name, student number, and exam version/form letter on the printed exam and bubble sheet using a #2 pencil before starting.
  • This is Version A, so section doesn't matter.
  • Show MSU ID (or photo ID) when turning in your bubble sheet and printed exam.
  • Choose one option per question and mark it on both the printed exam and bubble sheet.
  • Assume any needed #includes and using std::...; namespace declarations are performed for code samples.
  • Each question is worth the same amount; answer only 50 questions correctly out of 55 for a perfect score.
  • Electronics aren't allowed during the exam; put smart-watches, phones, and headphones in your bag.
  • The exam is open note; any paper material is allowed.
  • Place all materials on your desk before the exam to avoid rummaging through your bag.
  • Bring the required textbook.
  • Raise your hand if you have any questions during the exam, and a proctor will assist.

Exam Questions

  • To calculate the total points from exams, sum the highest scores from Midterm MCQ/Makeup, Midterm Coding/Makeup, Final MCQ, and Final Coding.
  • An interpreter differs from a compiler because it directly executes the code, it doesn't just interpret it.
  • CSE 232's policy on AI tools like GitHub Copilot and ChatGPT states that they can be used, but you must be cautious about using them in ways that deter learning. They can be used but only with attribution
  • Collaboration isn't permitted on exams.
  • The minimal C++ program has no specific traits from the list, thus the answer is that it "has none of the above" traits
  • Functions are overloaded when they share the same name but have different parameters (different arguments). In the provided declarations, Nice and Bark are overloaded.
  • According to the syllabus, always cite peers you collaborated with if you use them as a source.
  • Parameter names are not ignored by the compiler in function declarations when the function declaration is also a function definition.
  • Stroustrup's analogy of the book not being a layer cake means the book can be read in many different ways.
  • cout is contained in the std namespace.
  • The function call print(0,0) in Section 1.3 was ambiguous because (0,0) could be interpreted as one number or two.
  • The return type for a function that doesn't return anything is void.
  • To reduce errors, all function declarations should be included at the start of the file.
  • The -std=c++20 command-line argument for g++ is recommended to allow for C++20 features to be used in the code.
  • The C++ interpreter used in the course is not listed.
  • C++ was created to extend the programming language C.
  • For a function to be called, its declaration must occur prior to the function call in the code.
  • In print_square's definition with void, void means the function doesn't return any value.
  • If a function is overloaded, another function exists with the same name.
  • A program that turns a source file into an executable program is called a compiler.
  • To be overloaded, two functions must have the same name.
  • int main() {} is best described as a program definition.
  • STL is a namespace.
  • If code gives errors with -std=c++20 but works without it, the code is illegal according to the C++20 standard.
  • /* Comment */ is a comment in C++.
  • double other(); could be a function declaration (but isn't a function definition). Note the lack of {}.
  • Whitespace matters when it is in a string literal.
  • In the main function, a non-zero return value indicates failure.
  • With int x {7}; char y = hum(x + 8.9);, the return type of the function named hum is char.
  • Working through sample MCQ exam questions is recommended when studying.
  • The main function must be present in every C++ program.
  • Not using function overloading would eliminate ambiguous function calls.
  • The following program won't compile: 
    int twice(int x) {
  return x + x;
}
int main() {
  cout << twice("3");
}
  • int * Xyz::Abc(Xyz const &); is an example of a member function.
