北大C++ coursera课程

Week 2 A + B

#include 
using namespace std;int main()
{int a, b;cin >> a >> b;cout << a + b << endl;return 0;
}

Week 2 简单的学生信息处理程序实现
这里注意一下cin的数据，因为输入是逗号隔开的

#include 
#include 
#include   //不加的话直接编译报错，但可以在后面加上-std=c++11就可以通过
using namespace std;class Student_information{
private:char name[50];char id[50];int age;int score1, score2, score3, score4;
public:void init(char p[], char m[], int t, int a, int b, int c, int d){strcpy(name, p);strcpy(id, m);age = t;score1 = a;score2 = b;score3 = c;score4 = d;}int average_score(){return (score1 + score2 + score3 + score4) / 4;}void print_information(){cout << name << "," << age << "," << id << "," << average_score() << endl;}
};int main()
{char name[50];char id[50];int age;int s1, s2, s3, s4;cin.getline(name, 50, ',');cin >> age;char dot = getchar();cin.getline(id, 50, ',');cin >> s1 >> dot >> s2 >> dot >> s3 >> dot >> s4;Student_information A;A.init(name, id, age, s1, s2, s3, s4);A.print_information();return 0;
}
