  • ESC 151 –C Programming (ANSI C) Note on Medical Reasons For
    ESC 151 –C Programming (ANSI C) Class: Section 1: Remote, quizzes Monday at 9:30 Section 2: TTH 10:00 AM-11:15 AM Suggested External Information (in place of a book): http://www.cprogramming.com/tutorial/c- tutorial.html Instructor: Robert Fiske Office: FH 315, Office Hours/Availability: Officially: TTH 6:00-8:00 in general I’m available at any time except TTH: 9:00-12:30. Send me an email and if need be we can meet via zoom, if I don’t reply in a timely fashion send another email and/or post on the class discussion board. Note on medical reasons for extensions/other requirements Educational access is the provision of classroom accommodations, auxiliary aids and services to ensure equal educational opportunities for all students regardless of their disability. Any student who feels he or she may need an accommodation based on the impact of a disability should contact the Office of Disability Services at (216)687-2015. The Office is located in MC 147. Accommodations need to be requested in advance and will not be granted retroactively. Any medical/family issues you have need to be brought to my attention before you take any quiz/exam, once the exam is in your hands no makeup will be oered. Once you begin to take an exam/quiz you may not leave the room until you turn in the quiz/exam. Course Objectives: This course is designed to: 1. Introduce the C programming language. 2. Introduce the concepts of computer programming. 3. Teach students to think about how to approach programming challenges.

  • The Complete Guide to Return X;
    The Complete Guide to return x; I also do C++ training! [email protected] Arthur O’Dwyer 2021-05-04 Outline ● The “return slot”; NRVO; C++17 “deferred materialization” [4–23] ● C++11 implicit move [24–29]. Question break. ● Problems in C++11; solutions in C++20 [30–46]. Question break. ● The reference_wrapper saga; pretty tables of vendor divergence [47–55] ● Quick sidebar on coroutines and related topics [56–65]. Question break. ● P2266 proposed for C++23 [66–79]. Questions! Hey look! Slide numbers! 3 x86-64 calling convention int f() { _Z1fv: int i = 42; movl $42, -4(%rsp) return i; movl -4(%rsp), %eax } retq int test() _Z4testv: { callq _Z1fv int j = f(); addl $1, %eax return j + 1; retq } On x86-64, the function’s return value usually goes into the %eax register. 4 x86-64 calling convention Stack Segment int f() { Since f and test each have their own int i = 42; f i printf("%p\n", &i); stack frame, i and j naturally are different return i; prints “0x9ff00020” variables. } test j j is initialized with a int test() { copy of i — C++ : int j = f(); loves copy semantics. : printf("%p\n", &j); : return j + 1; prints “0x9ff00040” } main 5 x86-64 calling convention Stack Segment struct S { int m; }; Even for class types, C++ does “return by f i S f() { copy.” prints “ ” S i = S{42}; 0x9ff00020 The return value is printf("%p\n", &i); still passed in a test j return i; machine register } when possible. : : S test() { : S j = f(); prints “0x9ff00040” printf("%p\n", &j); main return j; } 6 x86-64 calling convention But what about when Stack Segment struct S { int m[3]; }; S is too big to fit in a register? S f() { f i Then x86-64 says that S i = S{{1,3,5}}; the caller should pass printf("%p\n", &i); an extra parameter, return i; pointing to space in } the caller’s own : return slot stack frame big : S test() { enough to hold the test: S j = f(); result.
