简单模拟___A+B

#include<iostream>
#include<cstring>
using namespace std;
int cmp(char *str)
{
	if (strcmp("zero", str) == 0)
		return 0;
	else if (strcmp("one", str) == 0)
		return 1;
	else if (strcmp("two", str) == 0)
		return 2;
	else if (strcmp("three", str) == 0)
		return 3;
	else if (strcmp("four", str) == 0)
		return 4;
	else if (strcmp("five", str) == 0)
		return 5;
	else if (strcmp("six", str) == 0)
		return 6;
	else if (strcmp("seven", str) == 0)
		return 7;
	else if (strcmp("eight", str) == 0)
		return   8;
	else if (strcmp("nine", str) == 0)
		return 9;
}
int main()
{
	while (1)
	{
		int s1 = 0, s2 = 0, sum;
		char str[20];
		while (cin >> str)
		{
			if (strcmp(str, "+") == 0)
				break;
			int num;
			num = cmp(str);
			s1 = s1 * 10 + num;
		}
		while (cin >> str)
		{
			if (strcmp(str, "=") == 0)
				break;
			int num = cmp(str);
			s2 = s2 * 10 + num;
		}
		if (s1 == 0 && s2 == 0)
			break;
		sum = s1 + s2;
		cout << sum << endl;
	}
	return 0;
}

此次问题也是相对的简单 就是对输入的字符串的判断 然后相应的返回对应的数值  这样我用到的输入与输出的方法是数据流的使用。
