求3个数字的最大值

话不多说，直接上代码：

#include<iostream>
using namespace std;
int main()
{
	int  a, b, c,max;
	cout << "Please enter 3 numbers:" << endl;
	cin >> a;
	cin >> b;
	cin >> c;
	if (a > b)
	{
		if (a > c)
			 max=a;
		else
			max=c;
	}
	else if (c > b)
		max=c;
	else 
		max=b;
	cout << "max number is" << max;
	return 0;
}
