การเขียนโปรแกรมแบบ stdio.h และ iostream.h

stdio.h

#include"stdio.h "
main()
{
int x,y;

printf("X :");
scanf("%d",&x);
printf("Y :");
scanf("%d",&y);
printf("\n\n");
printf("...............\n");
printf("x mod y = %d\n",x%y);
printf("x + y = %d\n",x+y);
printf("x - y = %d\n",x-y);
printf("x * y = %d\n",x*y);
printf("x / y = %d\n",x/y);
printf("...............\n");
}

iostream.h

#include"iostream.h "
main()
{
int x;
int y;

cout<<"X :"; cin>>x;
cout<<"Y :"; cin>>y;
cout<<"\n\n";
cout<<"...............\n";
cout<<"x mod y = "<< x%y<< endl;
cout<<"x + y = "<< x+y<< endl;
cout<<"x - y = "<< x-y<< endl;
cout<<"x * y = "<< x*y<< endl;
cout<<"x / y = "<< x/y<< endl;
cout<<"...............\n";
}
