我想要獲取變量：float managerTotal，hourlyTotal，commissionTotal和pieceworkerTotal從它們各自的函數打印在switch語句中：'q'在choiceInput函數中。昨天我有很多很多的錯誤，現在我讓它們通過，但是當我爲變量輸入一個輸入時，它不會傳遞值，它們只會返回0.請有人幫忙解釋我做錯了什麼。謝謝。C編程 - 返回不工作，因爲他們應該

注：我道歉，這是稍長的代碼，但原因我一直保留着這樣的說法是因爲上次我把它縮短它最終沒有工作對於我的實際代碼，只有我發佈的短代碼作爲示例。
尋求調試幫助的問題（「爲什麼不是這個代碼工作？」）必須包含所需的行爲，特定的問題或錯誤以及在問題**中重現**所需的最短代碼。沒有明確問題陳述的問題對其他讀者無益。請參閱：如何創建[mcve]。 – Olaf
