is char signed or unsigned? 工作这么多年,一直认为char是有符号的,而事实上gcc和vs默认也是有符号,但是c规范里实际并没有指明char是有符号还是无符号,所以char比较特殊, char signed char unsigned char 是三种数据类型,与int等是不一样的,int就等效为signed int。 gcc和vs都有选项设置char为unsigned。 arm开发...

某些程式設計語言,例如 C++,可辨識三個不同的char值:signed char、unsigned char和char。 為了區別未修改char的類型與其他類型,Microsoft C++ 編譯程式會將 修飾詞新增IsSignUnspecifiedByte至發出至元件的每個char類型。 編譯程式會在元數據內發出自定義修飾詞,以變更當預設行為不適用時,Just-In-Time (JIT) 編譯程序...

If a char is passed, the compiler may convert the value to a signed int or a signed long. This value may be sign-extended by the compiler, with unexpected results.The isw routines produce meaningful results for any integer value from -1 (WEOF) to 0xFFFF, inclusive. The wint_t data ...
top two values on the stack. The two items are removed, and if the first value pushed is greater than the second value, a 1 is pushed on the stack; otherwise, a 0 is pushed. The cgt instruction can also have the .un modifier applied to indicate the comparison is unsigned or ...
