cs106x-lecture1(Autumn 2017)

开始打卡cs106x(Autumn 2017)-lecture1

cs106x这门课的介绍： 主要通过 C++ 语言让学生在实际的编程作业里培养通过编程抽象解决实际问题的能力，同时也会涉及一些简单的数据结构和算法的知识，但总体来说没有一门专门的数据结构课那么系统。

1、CodeStepByStep-helloWorld

Write a complete C++ program with a main function that prints the following console output:

Hello, world!

解答

#include <iostream>
#include "console.h"

using namespace std;

int main() {
    cout << "Hello, world!" << endl;
    return 0;
}

2、CodeStepByStep-stanfordVsCal

Write a complete C++ program with a main function that computes who won the Stanford-Berkeley football game. The program should ask the user for the two scores. You may assume that the user enters valid non-negative integers. Below is an example dialogue (user input is shown like this):

Stanford: How many points did they score? 87
Cal: How many points did they score? 3
Stanford won!

解答

#include <iostream>
#include "console.h"
#include "simpio.h"

using namespace std;

int main()
{
    int stanford = getInteger("Stanford: How many points did they score?");
    int cal = getInteger("Cal: How many points did they score?");

    if (stanford >= cal) {
        cout << "Stanford won!" << endl;
    } else {
        cout << "Cal won!" << endl;
    }
    return 0;
}
