C/C++加减法计算题生成（源码）

一、源码

运行环境：Dev C++ 5.11

#include <bits/stdc++.h>
using namespace std;
struct question
{
	long long first;
	long long second;
}
t[1000001];
int main()
{
	long long Min, Max, add, minus, x = time(0) % 100, y = time(0) % 88;
	cout << "加法数量：";
	cin >> add;
	cout << "减法数量：";
	cin >> minus;
	cout << "MIN:";
	cin >> Min;
	cout << "MAX:";
	cin >> Max;
	for (int i = 1; i <= add; i++)
	{
		srand((time(0) + x + y + i) % 222);
		x += rand() % Max;
		srand((time(0) + x + add) % 111);
		y += rand() % Max;
		if (x > Max) x -= Max;
		if (y > Max) y -= Max;
		while (x + y > Max)
		{
			x -= rand() % x;
			y -= rand() % y;
		}
		t[i].first = x;
		t[i].second = y;
	}
	for (int i = 1; i <= minus; i++)
	{
		srand((time(0) + x + y + i) % 222);
		x += rand() % Max;
		srand((time(0) + x + minus) % 111);
		y += rand() % Max;
		if (x > Max) x -= Max;
		if (y > Max) y -= Max;
		t[i + add].first = x;
		t[i + add].second = y;
	}
	freopen("计算题练习.docx", "w", stdout);
	cout << Max << "以内";
	if (add != 0) cout << "加";
	if (minus != 0) cout << "减";
	cout << "法练习题" << endl << "姓名：_______________     ";
	cout << "试题数量：" << add + minus << "     时间：" << (add + minus) / 4 << "分钟" << endl;
	cout << "一、加法计算。（共" << add << "小题）" << endl;
	for (int i = 1; i <= add; i++)
		cout << i << ".  " << t[i].first << " + " << t[i].second << " =（    ）" << endl;
	cout << "二、减法计算。（共" << minus << "小题）" << endl;
	for (int i = 1 + add; i <= minus + add; i++)
		cout << i << ".  " << max(t[i].first, t[i].second) << " - " << min(t[i].first, t[i].second) << " =（    ）" << endl;
	cout << "答案" << endl << "一、加法计算。（共" << add << "小题）" << endl;
	for (int i = 1; i <= add; i++)
		cout << i << ".  " << t[i].first + t[i].second << endl;
	cout << "二、减法计算。（共" << minus << "小题）" << endl;
	for (int i = 1 + add; i <= minus + add; i++)
		cout << i << ".  " << max(t[i].first, t[i].second) - min(t[i].first, t[i].second) << endl;
	return 0;
}
