对于(int i=0;i
该错误以前没有出现,但当我决定在提交之前再次运行该程序时,出现了读访问冲突,因此我不确定是什么导致了它。

更改此项:

for (int j = 0; i < col - 1; j++)
for(int j=0;i
为此:

for (int j = 0; j < col - 1; j++)
for(int j=0;j
由于要检查
j
的条件,而不是
i

请更改此项:

for (int j = 0; i < col - 1; j++)
for(int j=0;i
为此:

for (int j = 0; j < col - 1; j++)
for(int j=0;j

既然您想检查
j
的条件,而不是
i

什么是
aPoint
intj=0;i
非常非常仔细地查看这个
for(intj=0;i
i
而不是
j
什么是
aPoint
intj=0;i
非常非常仔细地看这一个
,因为(intj=0;i
i
而不是
j
