正确程序之一为：
#include <iostream.h>
#define SQR(x) ((x)*(x))
void main(){
int counter;
}
3．
#define true 1
#define false 0
#define ok 2
#define error –1
#define overflow -2
4．
#define IFF(x) if(x%10==0)return true;else retrue false;
5．
#define EXCHANGE(x,y) x=x+y;y=x-y;x=x-y;

1.[程序如下]
#include <iostream.h>
struct student
{
float CPPscore;
float eng; for(counter=0;counter<5;++counter){ cout<<"x="<<(counter+1)<<" "<<"x的平方为"<<SQR(counter+1)<<'\n'; }
};
void main()
{
student s1; float sum; cin>>s1.CPPscore>>s1.eng;
sum=s1.CPPscore+s1.eng;
cout<<sum;
}
