可以把char index 换成 unsigned char index或者int index,但是至于int index为什么不报错,这个不太清楚了,可能int表示范围很大,一般不会越界变成负数吧。 警告: assignment discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers] 原因是const修饰的指针变量赋值给了普通指针变量。那么const修饰...

Re: passing argument 1 of 'memcpy' discards 'volatile' qualifier from pointer target « Reply #28 on: August 21, 2024, 01:57:01 pm » In terms of alignment, the arm cortex (edit: M4) processors, like most modern processors, support misaligned access in hardware. However it will tu...
constantchar*. Also possibly useful is the-Wcast-qualoption; this should emit a warning whenever a pointer is cast in a way that removes a type qualifier (in your case, theconstgot removed). If you want these messages to be made more strongly, use-Werrorto turn all warnings into ...
