## 心得感想
    在經過這次實習後我覺得我對寫程式的熟悉度又更高了，不再像第一次寫程式時那麼的不知所措也比較能聽得懂課程的內容，而且自己也越來越願意多花一點心思投入在其中，試著靠自己的力量去完成一個又一個練習，我希望未來的我可以越做越好。

## 0923實習心得(至少100字)
        在這次時實習課中，我覺得課程開始漸漸有了難度了，因為開始出現許多符號但這些符號卻與我原本所認知的意思不太一樣，所以我應該要跟勤勞的去練習如何運用這些符號，將他們運用在我的程式中，希望之後再看到這些符號時都可以快且正確地將其辨別出來。

## 0925實習心得(至少100字)
    在這次的實習完後我感到很開心，因為覺得自己寫出來的東西好像越來越貼近生活了，而不是說只侷限於考試課本，而是在生活中真正會用到的，希望我以後可以寫出許多實用且方便的程式，讓大家都可以以最簡單快速的方式去使用它。

## 05-24電影分級制度
下列程式將依據年齡層來判斷可觀賞的影片等級（0～5歲：普遍級、6～11歲：普
遍級及保護級、12～17歲：限制級以外的影片、18歲（含）以上：各級影片）。
    程式碼:
    #include<iostream>
using namespace std;
int main()
{
	int a;
	cout << "請輸入年齡 (0~120) :";
	cin >> a;
	switch(a){

## 05-27 猜數字遊戲
下列程式為一個猜數字遊戲（假設答案為7），遊戲會發出提示訊息要使用者輸入
所要猜的數字（1～10），若猜錯，遊戲會繼續進行，直到猜對為止。

若使用者未猜到答案時，要給予使用者提示（再大一點或再小一點），直到使用者猜對為止，該如何改寫程式呢？
（提示：在while迴圈中加入if條件判斷敘述。）
    程式碼:
#include<iostream>
using namespace std;
int main()
{
int n, ans = 7;
while(n != ans){
cout << "猜猜看數字是多少?(1~10):\n";
cin >> n;
if (n>7)
cout << "再小一點\n";
else
cout << "再大一點\n";
}
cout << "泥蠔蚌";
}

## 8. 密碼檢驗程式(P.133)
請設計一個密碼輸入次數不可大於三次的密碼檢驗程式，密碼=123，當密碼輸入正確請顯示:歡迎進入本系統。密碼輸入錯誤3次，無法登入。
    程式碼:
#include<iostream>
using namespace std;
int main(){
	int ww;
	for (int i=1;i<=3;i++){
		cout << "第"<< i <<"次輸入密碼";
		cin >> ww;
		if (ww == 413)
			break;
	}
	if (ww == 413)
	cout << "歡迎進入本系統";
	else
	cout << "密碼輸入錯誤3次，無法登入";
}

## 心得感想(至少100字):
    我覺得for跟while迴圈練習完還是有點模糊，所以我應該花更多的時間去練習，畢竟老師之前也有在課堂上講過，這個程式很重要，想當然我就不能擺爛鬼混過去，希望在之後的練習中，我可以慢慢地去理解，並完善的利用好這個程式。

## 心得感想(100字)(11/13):
    在這次課堂中我學到了函式，怎麼說呢?雖對函式的使用並沒有到非常熟悉，但我知道我必須得把它學好，因為之後再寫比較複雜的程式時一定得用到函式，所以我應該要多多利用函式去寫程式，慢慢拉近我與它之間的距離，日後要用到時，對它才不會太陌生。
