回复 7 楼 zklhp
你是说cout前不用加std::吗?
这几天我在想会不会是编译器不都的问题 我用的是VC6.0的 教程里是用C-Free5.0
全部代码在这
#include<iostream>
#include<fstream>
#include<windows.h>
using namespace std
struct
FishOil
{
std::string
name;
std::string uid;
char sex;
};

bool ReadFishC();
void RecordFishC();
bool WriteFishC(FishOil *OilData);
int main()
{
int i;
InitFishC();
while(1)
{
std::cout<<"请选择需要进行的操作: \n";
std::cout<<"1. 打印数据到屏幕\n";
std::cout<<"2. 录入数据\n";
std::cout<<"3. 退出程序\n";
std::cin>>i;
switch(i)
{
case 1:
if(ReadFishC())
cout<<"成功读取文件:";
else
cout<<"读取文件失败:";
break;
case 2:
RecordFishC();
break;
case 3:
return 0;
}
}
std::cout<<"初始化失败T_T......\n\n";
return 0;
}
bool InitFishC()

if(WriteFishC(&OilInit) == false)

}

for( int i =0; i<=100; i++)
