How to print out the memory contents of a variable in C?

Question

Suppose I do a

double d = 234.5;

I want to see the memory contents of d [the whole 8 bytes]

How do I do that?

Answer 1

I think you can use shift operation and mask to "mask out" the actual bits.

int t = 128;

for(int i=0;i<8;++i) { printf("%d", p & t);

p =>> 1;

t =>> 1; }
