int a = 1； float * p = & ampa；

This transformation can be compiled, but it is completely meaningless, mainly depending on the binary storage mode of float, and the resulting structure may not be what you want.

I feel that there is something wrong with the sentence "an int* pointer can only be assigned an element address of type int". LZ is just an int and a float (or double). If you use short or char to convert int, you can actually get the correct answer. Give a warning at most when compiling.

int a = 1； float * p = & ampa； char * p 1 = & amp； a；

The result of *p should not be 1, but the result of *p 1 must be 1.
