Question

write a procedure called power that will calculate integer powers of integer numbers. in other words, it will calculate x y given that both x and y are integers. 2. write a program that will call power to calculate x y on two numbers stored in appropriate registers. the answer should be placed in an appropriate register.

Answer 1

A procedure to calculate integer powers named 'power' would iterate a multiplication of the base number by itself an exponent number of times. A program would then call this procedure with two numbers from registers, and store the result in another register.

Step-by-step explanation:

Creating a Procedure to Calculate Integer Powers

To write a procedure called power that calculates integer powers of integer numbers, you would need to implement a loop that multiplies the base number x by itself y times. The pseudo-code can be conceptualized as follows:

procedure power(base, exponent)
result = 1
for i from 1 to exponent
result = result * base
end for
return result
end procedure

To write a program that uses power to calculate x to the y, where both x and y are integers stored in registers, and places the answer in a register, you’d do the following:

register1 = x
register2 = y
register3 = power(register1, register2)

This program stores the result of x raised to the power of y in register3. The process demonstrates not only the calculation of integer powers but also how to structure a simple program that interacts with registers.
