WebPointer in C is just a variable that could store the address of the other variable. In C size of a pointer is not fixed as it depends on Word size of the processor.

WebOct 15, 2024 · We first transform 64-bit integer representations of pointers to arrays of chars by calling memcpy. Then, we proceed by storing a pointer p into array arr by copying every byte of p. Note that condition (c1 == c2) is always true since both p and q have the same integer representation even though they point to different objects.
