【8086彙編(實驗)】 鍵盤輸出

實驗題目一

寫一個完整的8086彙編語言程序，從鍵盤輸入姓名，屏幕上輸出“hello，姓名”，如若從鍵盤輸入的是“Sam”，則從屏幕上顯示“hello，Sam”。

	output str1

實驗題目二

寫一個完整的8086彙編語言程序，滿足一下要求：
A. 數據段申請一個存儲數據的字長數據number1，該數據存儲的值12。
B. 數據段申請一個存儲數據的字長數據number2，該數據從鍵盤輸入。（提示從鍵盤鍵入該數據的ASCII值，轉換成數值後存入number2中）
C. 交換number1和number2的值，並且顯示交換後的值在屏幕上（提示數值需要轉化爲ASCII值才能進行輸出）。
假設從鍵盤輸入的值爲“20”，則顯示的信息爲：
The value of number1 is 20，the value of number2 is 12。
