这里可以看见M_dataplus表示实际存放数据的地方,当string是空的时候,其实就是指向M_local_buf,且_M_string_length是0。 当由char*构造string时,构造函数如下: 代码语言:javascript 代码运行次数:0 复制 Cloud Studio代码运行 basic_string(const_CharT*__s,size_type __n,const_Alloc&__a=_Alloc()):_M_data...
Java switch() case中的switch可用的数据类型 byte,shor,int ,string ,char 1.swtich()里面必须是int和enum--即枚举类型。 2.short、 char 或者 byte他会自动转换为int的。。 3.long不能自动转换为int,因为long比int范围大..可能会丢失精度.. 4.java把string也'转化'成int了,用string的hash值(int型,hashC...

same interfaces on the suppliedIFormatProvideras doesString.Format, so even implementations that supply anICustomFormattermay be used. Let’s say I wanted to change my example to print all of the integer values in hex rather than in decimal. We can achieve that using format specifiers, e.g...
