It seems like this:
 程序代码：int main() { student stud[3]={"li",1001,18,'f',"fun",1002,19,'m',"wang",1003,17,'f'}; ofstream outfile; outfile.open("example.txt",ios::trunc); if(!outfile) { cout<<"open error!"<<endl; return 1; } for(int i=0;i<3;i++) outfile<<stud[i].name<<" "<<stud[i].num<<" "<<stud[i].age<<" "<<stud[i].sex<<std::endl; outfile.close(); return 0; } |
程序代码：#include <fstream>
#include <iostream>
using namespace std;
struct student
{
char name[20];
int num;
int age;
char sex;
};
int main()
{
student stud[3]={"li",1001,18,'f',"fun",1002,19,'m',"wang",1003,17,'f'};
ofstream outfile("example.txt",ios::binary);
if(!outfile)
{
cout<<"open error!"<<endl;
return 1;
}
for(int i=0;i<3;i++)
outfile.write((char *)&stud[i],sizeof(stud[i]));
outfile.close();
return 0;
}
#include <iostream>
using namespace std;
struct student
{
char name[20];
int num;
int age;
char sex;
};
int main()
{
student stud[3]={"li",1001,18,'f',"fun",1002,19,'m',"wang",1003,17,'f'};
ofstream outfile("example.txt",ios::binary);
if(!outfile)
{
cout<<"open error!"<<endl;
return 1;
}
for(int i=0;i<3;i++)
outfile.write((char *)&stud[i],sizeof(stud[i]));
outfile.close();
return 0;
}
用的VC，与编译器有没有关系？
