前言

A=B

是一種虛構的程式語言(其實是個遊戲)

A=B,意思就是把"A"取代為"B",整個語言圍繞著這個邏輯運轉

 

這個程式語言,編譯時遵守下列規則:

1.每行必須有剛好一個 = 符號,不能多也不能少。
2.編譯時,跳過前面是 # 字符開頭的行(此為註解)。

執行時,遵守下列規則:

1.從第一行開始,由上往下執行,每次執行一行程式碼。
2.當發現到可以成功進行"取代"的程式碼,立刻適用該行程式碼,並取得新字串。
3.回到第一行,繼續由上往下執行。
4.若從第一行,到最後一行,都沒有成功進行"取代",程式結束,輸出最終字串。
5.執行時,跳過前面是 # 字符開頭的行(此為註解)。

原始碼

於VB.NET,開啟新專案 Windows Forms App (.NET Framework)

並將以下程式碼複製貼上到後端,即可執行
