This tosk is a text based task. You do not need to write any program/C++ file: the onswer
should be written in main.md (and might include code fragments if questions ask for
them).

appropriate pre- and postconditions.
1. function is_even:
bool is_even (unsigned int i) {
if (1 % 2 == 0) return true;
2. function invert:

Hint: The C++ compiler does not protect you from certain types of errors.
Therefore, even if you run a program in Code Expert, it is not guaranteed that the
behaviour you observe is the "real" one. We have prepared a program tracing
handout that shows how to execute a program with a pen and paper and which
conditions indicate bugs in the executed program not caught by the C++ compiler.
