[交流] 【求助】mac的编译环境xcode的使用问题

此程序，用visual studio编译完全没有问题，但是用mac下的xcode编译，却有11个错误？？？

CODE:

#include 

#include

#include

#include

using namespace std;

class ffts

{

private:

        double a,b,eps,integ;

public:

        ffts(double aa,double bb,double es)

        {a=aa;b=bb;eps=es;}

        void integration();

        void output();

        double func (double);

};

void ffts::integration()

{

        int n,k;

        double fa,fb,h,t1,p,s,x,t;

        fa=func(a);fb=func(b);

        n=1;h=b-a;

        t1=h*(fa+fb)/2.0;

        p=eps+1.0;

        while(p>=eps)

        {

                s=0.0;

                for(k=0;k
                {

                        x=a+(k+0.5)*h;

                        s=s+func(x);

                }

                t=(t1+h*s)/2.0;

                p=fabs(t1-t);

                t1=t;n=n+n;h=h/2.0;

        }

        integ=t;

}

void ffts::output()

{

        char str2[20];

        cout<<"\n输出文件名:"；

        cin>>str2;

        ofstream fout(str2);

        if(!fout)

        {cout<<"\n不能打开这个文件"<
        fout<
        fout.close();

}

double ffts::func(double x)

{ return exp(-x*x);｝

void main()

{

        ffts solution(0.0,1.0,0.000001);

        solution.integration();

        solution.output();

}
