我收到以下错误
q11.c:8:10:错误:无效的数字8,在八进制常量
q11.c:8:67:错误:无效的数字8,在八进制常量
q11.c:15:49:错误:无效的数字8,在八进制常量
q11.c:17:19:错误:无效的数字9,在八进制常量
q11.c:18:58:错误:无效的数字9,在八进制常量
q11.c:22:16:错误:无效的数字8,在八进制常量
q11.c:24:46:错误:无效的数字8,在八进制常量
解决方案
不要preFIX与 0
你的号码,除非你想让他们为八进制处理,这显然你不知道。所以只需要使用 8
而不是 08
。
如果你在藏在心里正确对齐,即使单个数字坚持,只是用空格代替零。

q11.c:24:46: error: invalid digit "8" in octal constant
解决方案
Don't prefix your numbers with 0
, unless you want them treated as octal, which clearly you don't. So just use 8
instead of 08
.
If you're insistent on keeping everything properly aligned, even with single-digit numbers, just use spaces instead of zeros.
