Question

Programming in C: Make a function that performs multiplication of two 32-bit unsigned integers.

Function definition:
long unsigned UnsignedMultiplier(unsigned multiplicand, unsigned multiplier);
where multiplicand and multiplier are two operands to multiply and the function returns the product.

Allowed operations:
All bit-level operations (&, |, ^, ~) and logical operations (&&, ||, !)
Left and right shifts
Equality (==), inequality (!=).
Less than (<) can be used only once.

2. Main function gets as input 2 integers in hex (use scanf with %x), prints them, as unsigned (use %u) and hex, then it calls UnsignedMultiplier, and then it prints results from UnsignedMultiplier as unsigned and hex.

Global variables not allowed.

Multiplicand & multiplier are w-bit unsigned integers. Initially, 2w-bit Product has Multiplier in its w lower bits and zeros in its w higher bits. Nothing to transcribe

Explanation / Answer

r = a * b r = ((ah > 16, rm1l = rm1 & 0xffff, rm2l = rm2 & 0xffff, rmh = rm1h + rm2h, rml = rm1l + rm2l; rl = rl + (rml
