#include<iostream>

using namespace std;
class Person
{
public:
char m_name[100];
int m_age;
};
void test()
{
ofstream ofs;
ofs.open("Person.txt", ios::out | ios::binary);
Person p;
p.m_name[100] = { "李四" };//"const char *" 类型的值不能用于初始化 "char" 类型的实体
p.m_age = 18;
ofs.write((const char*)&p, sizeof(Person));
ofs.close();
}
int main()
{
test();
return 0;
}
p.m_name[100] = { "李四" };
这种写法只能在数组定义的时候使用
可以修改为:
strcpy(p.m_name,"李四");
