Task 0101: Raw pointers (Slides 40-63)

What is the result of the following code? Would the program crash or cause undefined behavior?

Task 0102: Raw pointers (Slides 40-63)

Implement a function swap_values that enables the user to swap two given integer values.

Task 0103: Raw pointers (Slides 40-63)

Modify your code such that you can swap integer pointers instead

Task 0104: Raw pointers (Slides 40-63)

Draw a diagram for the main function in (0103) illustrating the heap/stack memory layout after swap_values has been called.

Task 0201: Arrays (Slides 64-93)

Given the C++ program below. Write down the state of the stack and the heap after each change to either one of them. Explain the consequences and potential problems of the statement a = nullptr;

Task 0202: Arrays (Slides 64-93)

Implement a recursive function with the following signature to perform a binary search on a given integer array: bool binary_search(const int* begin, const int* end, int key)...

Task 0203: Arrays (Slides 64-93)

Create a program that takes an arbitrary number of strings as command line arguments, reads them into a std::vector<std::string> and finally outputs them via cout using a range-based for...

Task 0301: Memory (Slides 40-112)

Re-implement the program from exercise (0101) using references instead of pointers.

Task 0302: Memory (Slides 40-112)

What is the output by the following code?

Task 0303: Memory (Slides 40-112)

For the given C++ code, answer the following questions: What is the type of each variable a-o ? Which assignments in the code are erroneous? Why?
