简单的编程,黑多错,新手``,看看

#include <iostream.h>
int Max(int x, int y);
void main()
{
int a, b, c;
cout<<"请输入a和b值:";
cin>>a>>b;
c=Max(a,b);
cout<<"a, b, c="<<a<<", "<<b<<", "<<c<<endl; //`修改为"
}
int Max(int x, int y)
{
if(x>=y) return x;
else return y;
}

#include <iostream.h>
int Max(int x, int y);
void main()
{
int a, b, c;
cout<<"请输入a和b值:";
cin>>a>>b;
c=Max(a,b);
cout<<"a, b, c="<<a<<", "<<b<<", "<<c<<endl; //C++输出单字符时是用双引号括起来的
}
int Max(int x, int y)
{
if(x>=y) return x;
else return y;
}
