Is it legal for a pointer of data type 'int' point to a float value?

Question

i think its illegal but I am not sure please someone tell me and thank you

Answer 1

C++ doesn't make many things illegal and you can get around them if you truely want. I've modified constants via pointers to prove it is doable and here print a float as an integer. Note that I also initialized the pointer with 0, which worked and tests to nullptr. However, I've been on a system that -1 was the value of nullptr as 0 was a valid addressable address so for safety use the symbol.
