下面是一个c程序，改写它，使它采用C ++风格的I/O语句。
# include<stdio.h>
int main()
{ int a,b,d,min;
printf ("Enter two numbers:“）；
scanf("%d%d",&a,&b);
min= a > b?b：a；
for(d=2; d<min; d++)
if(((a%d)==0)&&((b%d)==0))break;
if(d==min)
{ printf ("NO common denominators\n")；
return 0;
}
printf ("The lowest common denominator is %d\n",d) ;
return 0;
} 
# include<iostream> using namespace std; int main() { int a,b,d,min; cout<<"Enter two numbers:“； cin>>a; cin>>b; min= a > b?b：a； for(d=2; d<min; d++) if(((a%d)==0)&&((b%d)==0))break; if(d==min) { cout<<"NO common denominators\n"； return 0; } cout<<"The lowest common denominator is"<<endl<<d; return 0; }
