我們至少知道這些變量是什麼類型。 –

const int MAX_ID = 9999; const int MIN_ID = 1111; const float MAX_COST = 1500; const float MIN_COST = 0; –

'm_RAMsSize'，'m_ramSuffix'，'m_DiskSize'等如何？ –

m_labLocation = "SE135"

仔細查看該位。

但是你真正的問題應該是「我如何調試這樣的東西？」一種方法是將該龐大複雜的if語句分解爲若干較小的語句。這至少會減少你需要查看的代碼量。

例如：

bool validRam = 
    (m_RAMSize+m_ramSuffix) == "4GB" || 
    (m_RAMSize+m_ramSuffix) == "8GB" || 
    (m_RAMSize+m_ramSuffix) == "16GB" || 
    (m_RAMSize+m_ramSuffix) == "32GB"; 
bool validID = (m_idNumber >= MIN_ID && m_idNumber <= MAX_ID); 
    ... 
return validRam && validID && validType && validLocation && validDisk;

基本上，你只是保持你弄就成越來越小的線得到一個錯誤的行，直到你只有一小片碼左右的。
