         } 

請告訴我怎樣可以使這個代碼更優秀，short.here我必須去通過每個如果condition.which是時候consuming.i需要使它這樣，如果變量值是4，那麼它必須直接轉到4而不是通過每個if。

 if (image4click) 
     { 
      a = 1; 

     } 
     if (image4click1) 
     { 
      a = 2; 
     } 
     if (image4click2) 
     { 
      a = 3; 
     } 
     if (image4click3) 
     { 
      a = 4; 
     } 
     if (image4click4) 
     { 
      a = 5; 
     } 
     if (image4click5) 
     { 
      a = 6; 
     } 
    in this image4click is boolean variable.how to shorten this make it better. 

Answer 1

我不確定你正在使用哪種語言，但在編程中有一些稱爲switch-case的東西。

switch 
     case 1: 
     do this... 
     case 2: 
     do this... 
     case 3 
     do this... 
    end 

很明顯，你將不得不看看你正在使用的編程語言的語法。希望這可以幫助！
