Question

C++一闪而过的程序结果，加了GETCHAR了

#include<iostream>
#include<math.h>
using namespace std;
double max (double x,double y);

int main ( )
{double a,b,c;
cout<<"\a please input the two number:\n";
cin>>a>>b;
c=max(a,b);
cout<<" the squart of maxinum="<<sqrt(c);
getchar( );
return 0;
}

double max (double x,double y)
{if(x>y)
return x;
else
return y;
}

为什么啊

Answer 1

你把getchar( ); 改成system("PAUSE");算了

Answer 2

换成cin.getch()
