計程C++ 關於if&else if

[magicken (追尋酸甜的片段)]

就是三個數字比大小的問題

else if本雞會用了^^

可是....if....(把a b c 關係全列出來的)

會有問題(麻煩看倌對以下的碼輸入 5 8 1測試)

#include <iostream>
using std::cout;
using std::cin;
using std::endl;
int main()
{
        int a;
    int b;
        int c;
        int d;
        int e;
        int f;
        cout << " Input three different intergers: \n";
        cin >> a>>b>>c;
d=a+b+c;
f=a*b*c;
if (a<b<c)
{

cout << "Smallest is =" << a << endl;
cout << "Largest is =" << c <<endl;}
else if (a<c<b)
{
cout << "Smallest is =" << a <<endl;
cout << "Largest is =" <<b<<endl;}
else if (b<a<c)
{
cout << "Smallest is =" <<b<<endl;
cout << "Largest is =" <<c<<endl;}
else if (b<c<a)
{
cout << "Smallest is =" <<b<<endl;
cout << "Largest is =" <<a<<endl;}
else if (c<a<b)
{
cout << "Smallest is =" <<c<<endl;
cout << "Largest is =" <<b<<endl;}
else if (c<b<a)
{
cout << "Smallest is =" <<c<<endl;
cout << "Largest is =" <<a<<endl;}

        return 0;
}

     靜靜的看著你是現在的我最大的快樂
  雖然我從不承認但對你我願意付出我的一切
      或許這是前世的冤孽讓我如此痛苦
            但我並不敢奢求太多
        只希望我們兩個能永遠在一起
             不論發生了什麼事..........

推 pg30123:建議使用if(a<=b && a<=c)
推 magicken:喔^^  如果不唸ㄐㄧㄝˊ 要唸什麼啊?
