Write an unsigned 16-bit implementation of multiplier and divider architectures.

Question

Write an unsigned 16-bit implementation of multiplier and divider architectures. You need to follow the Multiply and Divide algorithms to implement this. You must not use MIPS multiplication or division instructions.

The output of the program must include product, quotient and remainder. Also, the program must check for “0” as an input and must give error message for divide-by-zero operation.

Example:
Enter an integer (a): 14
Enter another integer (b): 3
Product: 42
Quotient (a/b): 4
Remainder (a/b): 2
Quotient (b/a): 0
Remainder (b/a): 3
Divide-by-zero

Example:
Enter an integer: 14
Enter another integer: 0
Product: 0
Quotient (a/b): Sorry, divide-by-zero not allowed
Quotient (b/a): 0
Remainder (b/a): 0
