「Error：expected expression before」我的函數的第一行

Question

我正在編譯時遇到此錯誤...「stock.c：103：錯誤：'stock_t'之前的期望表達式」...是否有一些我做錯了什麼？

stock_t * createStockHolding(
    char * name, float closing, float opening, int shares, 
    float (* getPrice) (void * S), 
    float (* getTotalDollarAmount)(void * S), 
    float (* getPercentChange)(void * S), 
    char * (* toString)(void * S)) { 

     stock_t * newStock = (stock_t*)malloc(sizeOf(stock_t)); 
     newStock->stockSymbol = name; 
     newStock->closingSharePrice = closing; 
     newStock->openingSharePrice = opening; 
     newStock->numberOfShares = shares; 
     newStock->getPrice = getPrice; 
     newStock->getTotalDollarAmount = getTotalDollarAmount; 
     newStock->getPercentChange = getPercentChange; 
     newStock->toString = toString; 
     return newStock; 
}  

Answer 1

它是sizeOf的大寫字母O.您必須使用sizeof（小號o）。
