1、实验目的及要求
Before you enter the following program in the computer, please point out the errors of it, then analyze and correct the errors.
ttinclude <iostream. h>
int n;
void main ()
(
double m=3. 8;
cout〈<〃n=〃<〈n〈〈endl;
fn();
}
void fn()
(
cout<<zzm=，/<<m<<endl;
cout〈<〃n=〃<〈n〈〈endl;
}
Before you enter the following program in the computer, please read it and write down the output results of the program. Then, you can test the results in the computer by compiling and running it in VC++.
ttinclude <iostream. h> void func ();
int n=l;
int main()
{
static int x=5;
int y;
y=n;
cout<〈〃x二〃<<x++〈<〃，y=/，«++y«/，, n=，，«n«endl;
func ();
cout<〈〃x二〃<<x++〈<〃，y=/，«++y«/，, n=，，«n«endl;
func ();
}
void func ()
(
static int x=4;
int y=10;
x+二 3;
n+二10;
y+=n;
cout<<〃x二〃y=〃n=，/<<n<<endl;
}
Before you enter the following program in the computer, please give the results of the following program of Macros. Then, you can test the results in the computer by compiling and running it in VC++.
ttinclude <iostream. h>
ttdefine f(x) x*x
void main ()
(
cout<<f(4+4)<<endl;
cout<<f(2+2)<<endl;
cout<<f (4+4)/f(2+2)<<endl;
}
Based on the following namespace and what we have learned about namespace, please use two or three dif
