1. Write CppUnitLite tests to verify correct behavior for all the exercises. Using C++

2. Please show all outputs.

Write functions to add one day, another function to add one month, and yet another function to add one year to a Date struct.

struct Date { int year; int month; int day; }; 

Pass Dates by reference when appropriate (i.e., Date& or const Date&). For example, the following function returns by value a new Date instance with one day added to the passed in date.

Date addOneDay(const Date& date); 

Create a C++ header file named write.h which contains function prototypes for three functions named write. Write the implementations for each write function in a file named write.cpp. Each write function takes two arguments. The first argument is always std::ostream& os. The second arguments are an int, a float, and a std::string respectively. Each write function should stream its second argument to the passed in std::ostream. Write cppunitlite unit tests that pass a std::stringstream as the first argument to each function and verify its operation. Write non unit test code that calls each write function and passes std::cout as the first argument (the cout tests are written outside the unit test framework because verification can't easily be automated). Here's the prototype for the first write overload:

void write(std::ostream& os, int value);

Notice that both std::stringstream and std::cout may be passed as the first argument. Both inherit from std::ostream and thus may be used where ever a std::ostream& is used. This is our first use of inheritance in C++. We'll do much more with inheritance as the course progresses.

Write a lambda function which makes the following TEST pass:

TEST(lambdaTestProblem, lambdas) { auto values = { 2, 4, 6, 8, 10, 12 }; auto sum = 0; std::for_each(values.begin(), values.end(), /*define lambda function here*/); CHECK_EQUAL(42, sum); }
