《C++ Primer Plus》，6-7，程序运行时卡住了
题目来自《C++ Primer Plus》，编号6-7。编译环境为Microsoft Visual Studio C++ 2010
题目太长，就先不打了...不好意思（¯﹃¯），劳烦有条件的童鞋请自行拿书看下了。
#include <iostream>#include <string>#include <cstring>#include <cctype>using namespace std;int main(){ struct donors { string name; double donation; }; int num; cout << "enter the num plz"; cin >> num; donors *p = new donors[num]; cout << "now enter data plz\n"; for (int i = 0;i < num;++i) { cin >> p[i].name; cin >> p[i].donation; } cout << "Grand Patrons\n"; int count = 0; for (int i = 0;i < num;++i) { if (p[i].donation > 10000) { cout << p[i].name << '\t' << p[i].donation << endl; ++count; } } if (count = 0) cout << "none\n"; cout << "Patrons\n"; count = 0; for (int i = 0;i < num;++i) { if (p[i].donation <= 10000) { cout << p[i].name << '\t' << p[i].donation << endl; ++count; } } if (count = 0) cout << "none\n"; delete p; return 0;}
