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. In general a 32-bit computer machine then size of a pointer would be 4 bytes while for a 64-bit computer machine, it would be 8 bytes.

WebBut PTR directive helps accessing a byte in an array, like, MOV AH, BYTE PTR WORDS. (c) PTR directive finds usage in indirect jump. For an instruction like JMP [BX], the assembler cannot decide of whether to code the instruction for a NEAR or FAR jump. This difficulty is overcome by PTR directive.

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.
