Assignment 0: C++ warm-up. The purpose of this assignment is to familiarize ourselves with C++, cmake, and github.
Windows
Open git bash to the directory containing this repository.
cpp-warmup $ mkdir build
cpp-warmup $ cd build
cpp-warmup $ cmake -G "Visual Studio 16 2019" ..
cpp-warmup $ make
Then open the solution file to write and test your programs.
macOS
Open terminal to the directory containing this repository.
cpp-warmup $ mkdir build
cpp-warmup $ cd build
cpp-warmup $ cmake ..
cpp-warmup $ make
To run each program from build, you would type
cpp-warmup $ ../bin/fizzbuzz
cpp-warmup $ ../bin/testcircle
In the file fizzbuzz.cpp
, implement the program FizzBuzz, described here.
In case you might not be familiar with reading and writing data from the console, we've given you the following starter code.
#include <iostream>
using namespace std;
int main(int argc, char** argv)
{
int X,Y,N;
cin >> X;
cin >> Y;
cin >> N;
// your code here
}
This program will sit and wait until you enter 3 values.
Write a class, circle, that stores a radius and has the following methods
- default constructor (radius is set to 0)
- constructor taking a radius as argument
- copy constructor
- assignment operator
- output stream operator
- add operator (should add the radii of two circles together)
- accessor (e.g. getter) for radius
- mutator (e.g. setter) for radius
- method for computing and returning the area
- destructor
Your class should also
- Split the class into a header and implementation file
- Define its methods as public, but data (the radius) as private
For example, running the program, testcircle.cpp
, should give the following output.
#include <iostream>
#include "circle.h"
int main(int argc, char** argv)
{
Circle c1;
Circle c2(10);
Circle c3 = c2;
Circle c4 = c2 + c2;
std::cout << "--------- Starting Values ----------\n";
std::cout << "c1: " << c1 << std::endl;
std::cout << "c2: " << c2 << std::endl;
std::cout << "c3: " << c3 << std::endl;
std::cout << "c4: " << c4 << std::endl;
float area = c3.computeArea();
std::cout << "Circle 3 has area: " << area << std::endl;
c2 = c1;
c1.setRadius(c3.getRadius() + 2);
std::cout << "--------- Ending Values ----------\n";
std::cout << "c1: " << c1 << std::endl;
std::cout << "c2: " << c2 << std::endl;
std::cout << "c3: " << c3 << std::endl;
std::cout << "c4: " << c4 << std::endl;
}
Output
--------- Starting Values ----------
c1: 0
c2: 10
c3: 10
c4: 20
Circle 3 has area: 314.159
--------- Ending Values ----------
c1: 12
c2: 0
c3: 10
c4: 20
