Modern-Only C++ Course - Homework
This repository contains the homework for Lesson 4.
Be Positive
Implement a function be_positive (in the file bepositive/bepositive.cc) that changes elements with negative values to their absolute values and returns the number of changed elements.
The goal is to have the following commands pass without any errors:
bazel test //bepositive/...
bazel test --config=addrsan //bepositive/...
bazel test --config=ubsan //bepositive/...
Reverse
Implement a function reverse (in the file reverse/reverse.cc) that reverses the order of elements in a std::span.
The goal is to have the following commands pass without any errors:
bazel test //reverse/...
bazel test --config=addrsan //reverse/...
bazel test --config=ubsan //reverse/...
People DB
Given a database of people, implement functions lookup, highest_tenure, and youngest_person (in the file people/people.cc) that do the following:
lookup: Look up a person in the database by IDhighest_tenure: Return the person with the lowest IDyoungest_person: Return the person with the highest year_of_birth
Hint: You will find the global variable null_person useful.
The goal is to have the following commands pass without any errors:
bazel test //people/...
bazel test --config=addrsan //people/...
bazel test --config=ubsan //people/...
Word Count
Implement the single-line and multi-line versions of functions wordcount and instances (in the file wordcount/wordcount.cc) that count the number of words in a line/text and count the number of instances of a word in a line/text.
The goal is to have the following commands pass without any errors:
bazel test //wordcount/...
bazel test --config=addrsan //wordcount/...
bazel test --config=ubsan //wordcount/...
