標題: 單片機程序錯誤就是看不懂哪里錯了,提示syntax error語法錯誤
總是提示這個括號有錯誤，如果我只有三個加法按鍵程序就沒有問題，但是我加了減法按鍵就提示錯誤。希望大佬看一下找一下錯誤。這個程序是按鍵加法減法數碼管顯示。

錯誤在else if(keycode==0x34)|(keycode==0x35）下的那個中括號，提示syntax error語法錯誤

作者: hhdsdy 時間: 2019-11-2 20:01
if括號需要配對，你的這句最后面就沒有反括號
else if((keycode==0x34)|(keycode==0x35)|(keycode==0x36)|(keycode==0x25)

else if((keycode==0x34)|(keycode==0x35)|(keycode==0x36)|(keycode==0x25)這里少了個“）”，一般這種錯誤只要點擊錯誤提示就會跳到這里(有的編譯器會有誤差，但是差不多就是在出錯的語句前后)，然后纖細檢查下語法就能發現錯誤。好的編譯器可能還會提升少了一個“）”。不過是英文的。

地板說的對,你這個程序少了個括號
