结对编程 小学四则运算

程序代码

#include<iostream>
#include<vector>
#include<algorithm>
#include<string>
#include<map>
#include<stack>
using namespace std;
int check(int s1, int s2, int s3, char c1, char c2) {int num1;int num2;if (c2 == '*' || c2 == '/') {if (c2 == '*')num2 = s2 * s3;else if (c2 == '/') num2 = s2 / s3;if (c1 == '+') num1 = s1 + num2;else if (c1 == '-')num1 = s1 - num2;}else {if (c1 == '+') num1 = s1 + s2;else if (c1 == '-')num1 = s1 - s2;if (c2 == '+') num1 += s3;else if (c2 == '-')num1 -= s3;}if (num1 < 0 || num1>1000)return -1;return num1;
}
int main() {vector<char>ans = { '+','-','*','/' };int n = 6;while (n > 0){for (int i = 0; i < 50; i++) {int s1 = rand() % 100;int s2 = rand() % 10 + 1;int s3 = rand() % 100 + 1;s2 = s2 * s3;int rans1 = rand() % 2;int rans2 = rand() % 4;int res = check(s1, s2, s3, ans[rans1], ans[rans2]);if (res == -1) {i--;continue;}cout << s1 << ans[rans1] << s2 << ans[rans2] << s3 << "=";int result;cin >> result;if (result == res)cout << "yes" << endl;else cout << "no" << endl;}cout << "已经完成50道题了 休息一下吧~" << endl;n--;cout << "是否继续？1:继续 0：退出" << endl;int value = 0;cin >> value;if (value != 1){break;}}return 0;
}

50题做完后可选择重新运行程序或退出

博客体会
结对编程给我带来一种全新的心得体会，以前一直认为编程偏向于自我的思考，但结对编程过程中，和队友的交流也尤为重要。两个人同时对一个程序进行编写和修改，让我们的代码编写更加顺利，也犯了更少的错误。
