我觉得是unspecified behavior, evaluation order of LHS and RHS
is unspecified. f()的"return i-1"之后有一个sequence point, 所以不存在两个
sequence points之间存在多个writes的问题。
这里我认为是正确的
不过这个程序里，存在一个undefined behavior, main函数必须return一个int，否则
是UB. |

auto x = y; //x.typeid() == y.typeid()
很少看到下面的写法，为什么呢？
auto x("hello"); |

发帖数: 59 | 3 After compiling, I ran the program. Linux gave me this error
message and nothing else.
When I use debugger to debug, entering some function ( I
guess that contains some mistakes), the message is :
__eq__H3ZcZt18string_char_traits1ZcZt24__default_alloc_templ
ate2b1i0_RCt12basic_string3ZX01ZX11ZX21PCX01_b
(lhs=@0xbffff75c, rhs=0x804f801 "") at
../../../libstdc++/std/straits.h:125
Does this mean something wrong with standard lib file? Or I
used them wrong? Or, something else???
Please tell me why, |
