java - FC_COLS的原始类型int没有inBlockSize字段

我在lastStartCol = FC_COLS – inBlockSize;上收到此错误，并在lastStartCol = ECONOMY_COLS – inBlockSize;上收到类似错误。也不确定我的老师希望我用for语句做什么。简单的答案表示赞赏。

//确定lastStartCol，即行中给定块//的最后合法起始列。

if(inRow < FC_ROWS)
    lastStartCol = FC_COLS – inBlockSize;
else
    lastStartCol = ECONOMY_COLS – inBlockSize;


for(int startCol = 0; startCol <= lastStartCol; startCol++)
{
    ...

最佳答案

我的理解是打字错误。

在此行lastStartCol = FC_COLS - inBlockSize;中尝试此操作，首先删除此-，然后再次从键盘输入减号。

在此行中也执行上述操作lastStartCol = ECONOMY_COLS - inBlockSize;

要么

尝试用下面的代码替换您的代码行。

if(inRow < FC_ROWS)
    lastStartCol = FC_COLS - inBlockSize;
else
    lastStartCol = ECONOMY_COLS - inBlockSize;
