为什么我不能像预期的那样初始化 long long?

Why can I not initialize a long long as expected?

我的 VC2017 编译器出现了这种行为,谁能解释一下这是怎么回事?:

long long testLLSigned0 = LLONG_MIN; // OK, equal to -922129006921510580
long long testLLSigned1 = -922129006921510580i64‬; // Error, invalid suffix i64 on integer constant
long long testLLSigned2 = -922337203685477580i64; // OK!
long long testLLSigned3 = -922337203685477580LL; // OK!
long long testLLSigned4 = -‭62129006921510911‬LL; // Error, use of undeclared identifier ‭62129006921510911‬LL
long long testLLSigned5 = -‭62129006921510911i64‬; // Error, use of undeclared identifier ‭62129006921510911i64

感谢Eljay, NathanOliver, eerorika & user1810087,我解决了

代码未编译的最大原因是将计算值从 Windows 计算器 (!) 复制到任何现代编辑器 (!)。值 62129006921510911 被复制到编辑器中 invisible unicode 字符!粘贴到 vim 时的结果显示:-<202d>62129006921510911<202c>LL

旁注:使用 LL 语法,i64 语法特定于 Microsoft,不可移植。
