C++三只小猪谁最重

C++选择结构学习小案例

#include
using namespace std;

int main()
{
	int A = 0;
	cout << "请输入小猪A体重" << endl;
	cin >> A;
	int B = 0;
	cout << "请输入小猪B体重" << endl;
	cin >> B;
	int C = 0;
	cout << "请输入小猪C体重" << endl;
	cin >> C;
	cout << "小猪A：" << A << "kg\n" << "小猪B：" << B << "kg\n" << "小猪C：" << C << "kg\n" < B && A > C)
	{
		cout << "小猪A最重,重达" << A << "kg" << endl;
	}
	else if (A < B || A < C)
	{
		if (B > C)
		{
			cout << "小猪B最重,重达" << B << "kg" << endl;
		}
		else if (B == C)
		{
			cout << "小猪B和C一样重,重达" << B << "kg" << endl;
		}
		else
		{
			cout << "小猪C最重,重达" << C << "kg" << endl;
		}
	}
	else if (A == B && A > C)

	}
	else if (A == C && A > B)
	{

	}
	else

	}

	system("pause");

	return 0;
