In Swift we have a powerful high-level logic abstraction, while low-level operations are deliberately limited. But in some cases we still want to do some hack work in C, and the cat will take a look at how to do it.Hacking is happy!!! ;]As the title says, now I have an int variable x, I want to get its address, then convert it to char type address, and then change the address of the content +1, if the C language to represent is:121,*pi = xchar *pc = (char *)pi1There are 2 questions to be written
