Please help me fix the following error. I have attched the line of code below as well (if possile, please retype the code):

complextester.cpp:21:1: error: expected unqualified-id before ‘{’ token 21 | { | ^

 

The first time indicates line 21:1

 

{
    Complex z0(3.6,4.8);
   Complex z1(4,-2);
   Complex z2(-4,2);
   Complex z3(-4,-3);
   Complex z4(3,-4);
   Complex z5;
   Complex z6;
   Complex z7;
   Complex ang;
   cout<<"z0 = "<<z0<<" and re(z0) = "<<z0.getReal()<<" and "
       <<"im(z0) = "<<z0.getImag()<<"."<<endl;
   cout<<"z1 = "<<z1<<endl;
   cout<<"z2 = "<<z2<<endl;
   cout<<"z3 = "<<z3<<endl;
   cout<<"z4 = "<<z4<<endl;

   cout<<"z2 x z3 = "<<z2*z3<<endl;
   cout<<"z1 + z2 = "<<z1+z2<<endl;

   cout<<"z3 = "<<z3<<endl;
   cout<<"z4 = "<<z4<<endl;
   cout<<"z3-z4 = "<<z3-z4<<endl;
