你应该这么问：
using namwspace std; 这行编译器报错为：syntax error : missing ';' before identifier 'std'，'namwspace' : symbol cannot be used in a using-declaration

别人就会立即看出你把 namespace 拼写错了

#include<iostream>
using namespace std;
int main()
{
    double a,b,c;
    char x,y,z;
    cout<<"请输入科目："<<endl;
    cin>>x>>y>>z;
    cout<<"请输入对应成绩："<<endl;
    cin>>a>>b>>c;
    cout<<endl;
    cout<<"        成绩单       "<<endl;
    cout<<"-------------------- "<<endl;
    cout<<"|"<<"x"<<"|"<<"y"<<"|"<<"z"<<"|"<<endl;
    cout<<"|"<<setiosflangs(ios::fixed)<<setiosflangs(ios::right)<<setprectsion(7)<<setw(2)<<"a"<<"|"<<"b"<<"|"<<"c"<<endl;
    cout<<"-------------------- "<<endl;
    return 0;
}
上面我改了，仍然编不了，为何？拜托高手帮解决啊

楼主你也太粗心了吧，这么多拼写错误。请注意是setiosflags.还有setprecision.
#include<iostream>
#include<iomanip>
using namespace std;
int main()
{
    double a,b,c;
    char x,y,z;
    cout<<"请输入科目："<<endl;
    cin>>x>>y>>z;
    cout<<"请输入对应成绩："<<endl;
    cin>>a>>b>>c;
    cout<<endl;
    cout<<"        成绩单       "<<endl;
    cout<<"-------------------- "<<endl;
    cout<<"|"<<"x"<<"|"<<"y"<<"|"<<"z"<<"|"<<endl;
    cout<<"|"<<setiosflags(ios::fixed)<<setiosflags(ios::right)<<setprecision(7)<<setw(2)<<"a"<<"|"<<"b"<<"|"<<"c"<<endl;
    cout<<"-------------------- "<<endl;
    return 0;
}

我也正在学c++。用的是vs 2008的，编译有错时，是以中文来提示的，方便很多，建议你也用用
