1.1
#include <iostream>
using namespace std;
int main()
{cout<<"This is a C++ program.";
return 0;
}
1.2
#include<iostream>
using namespace std;
int main()
{
int a,b,sum;
cin>>a>>b;
sum=a+b;
cout<<"a+b="<<sum<<endl;
return 0;}
1.3
#include<iostream>
using namespace std;
int max(int x,int y)
{
int z;
if(x>y) z=x;
 else z=y;
return(z);
}
 
int main()
{
int a,b,m;
cin>>a>>b;
m=max(a,b);
cout<<"max="<<m<<'\n';
return 0;
}
或
#include <iostream>
using namespace std;
int main()
{
int max(int x,int y);
int a,b,c;j
cin>>c>>b;
c=max(a,b);
cout<<"max="<<c<<endl;
return 0;}
 
int max(int x,int y)
{
int z;
if (x>y) z=x;
  else z=y;
 return(z);
}
1.4
#include <iostream>
using namespace std;
class student
{private:
   int num;
   int score;
 public:
    void setdata()
     {cin>>num;
      cin>>score;}
    void display()
     {cout<<"num="<<num<<endl;
      cout<<"score"<<score<<endl;};
    };
   student stud1,stud2;
int main()
{stud1.setdata();
 stud2.setdata();
 stud1.display();
