Can Structures Be Passed To The Functions By Value? CISC emphasise on hardware rather that software, making it costlier than RISC. The void pointer means that it points to a variable that can be of any type. CISC (Complex Instruction Set Computer) is capable of executing multiple operations through a single instruction. This is to inform the compiler that pointer p is pointing to an integer and the value of that integer may change unexpectedly even if there is no code indicating so in the program.
