小弟初学C++ 第一个作业就有问题~实在不懂了 求指教~
#include<iostream>
using namespace std;
{
    cout<<"sizeof(char)    :"<<sizeof(char)<<endl;
    cout<<"sizeof(bool)    :"<<sizeof(bool)<<endl;
    cout<<"sizeof(short)    :"<<sizeof(short)<<endl;
    cout<<"sizeof(int)    :"<<sizeof(int)<<endl;
    cout<<"sizeof(unsigned)    :"<<sizeof(unsigned)<<endl;
    cout<<"sizeof(long)    :"<<sizeof(long)<<endl;
    cout<<"sizeof(float)    :"<<sizeof(float)<<endl;
    cout<<"sizeof(double)    :"<<sizeof(double)<<endl;
    cout<<"sizeof(long double)    :"<<sizeof(long double)<<endl;
    system("pause");
}

错误    1    error C2447: “{”: 缺少函数标题(是否是老式的形式表?)    c:\users\ace\documents\visual studio 2008\projects\biabia1\biabia1\数据类型长度.cpp    3    biabia1
