中文意思不解释。
很水,我本来想用switch处理字符串,然后编译不通过。。。原来switch只能处理整数型的啊,我都忘了。
然后就有了很挫的一大串if代码了。。。
代码:
#include <iostream> #include <string> using namespace std; int digit(string str) { if (str == "zero") return 0; if (str == "one") return 1; if (str == "two") return 2; if (str == "three") return 3; if (str == "four") return 4; if (str == "five") return 5; if (str == "six") return 6; if (str == "seven") return 7; if (str == "eight") return 8; if (str == "nine") return 9; return -1; } int getval() { string tmp; int s = 0; while (cin >> tmp && tmp != "+" && tmp != "=") { s = s * 10 + digit(tmp); // cout << tmp << endl; } return s; } int main() { int p1, p2; while (1) { p1 = getval(); p2 = getval(); // cout << p1 << " + " << p2 << " = "<< endl; if (p1 == 0 && p2 == 0) break; cout << p1 + p2 << endl; }//while return 0; }
