6:字符串型和定义类型同义词
include "stdafx.h"
#include <iostream>//引用要不std之类的无法使用
#include <string>//字符串型
using std::cout;
using std::endl;
using std::string;//字符串型
int total;
string strsum,strin;
int _tmain(int argc, _TCHAR* argv[])
{
int innum;
strsum="合计一共;";
strin="请输入金额";
while(1)
{
cout << strsum << total << endl;
cout << strin << endl;
cout << tes << endl;
if (std::cin >> innum )
{
total += innum;
system("cls");
}
else
{
cout << "No date" << endl;
}
}
typedef string str;//typedef 用来定义类型的同义词
str tes;
tes="ookk";
return 0;
}
