用C填充形状 | 码农家园

fill shape with C

我写了一个程序，用星号填充闭合的数字。出于某种原因，它不接受sentinel值eof(ctrl-d)。为什么会这样？

int sentinel = 0;
int temp = 0;

j++;
}
i++;
lines++;
}
for (i = 0; i < lines; i++) {
fill(shape, i, width);

//for (i = 0; i < lines; i++)
showshape(shape, lines, j+2);
}

好的，刚刚更新了代码。这个盒子印的不太好。发生什么事？？

代码的另一个更新。这次我复制了温度值。但是，我得到了Bus error--我做错了什么？！
