Question

1.Write pseudocode for a program that allows the user to input two numbers (X and Y) and a code C. If the code has value 1, the program should output the larger of X and Y and otherwise output the smaller.

Now convert your pseudocode to an assembly language program. Enter the program into the lab software assembler. Assemble the program and execute it with different input data.

2. Write pseudocode for a program that allows the user to input a positive number N. The program should output 1 if the number is odd and output 0 if the number is even.

3.Our assembly language has no operator for multiplication. But multiplication can be performed by repeatedly adding one number to a running total and reducing the other number by one until the second number becomes zero. Write and test an assembly language program that displays the product of two input numbers.

Answer 1

1. pseudocode

{
In the main function

print prompt "Input number X"
print prompt "Input number Y"
print prompt "Input Code C"

If Code == 1
If X > Y
Set largest = X
If X < Y
Set largest = Y
print the largest to the user
else
If X < Y
Set smallest = X
If X > Y
Set smallest = Y
print the smallest to the user

}

2.psedocode

{
In the main function

print prompt "Input number N"

If N%2 == 1
print 1 to the user
else
print 0 to the user

}

3.

{
In the main function

print prompt "Input number X"
print prompt "Input number Y"
set Temp = 1
set Sum = 0
while (Temp < =Y)
Sum = sum + X
Temp = Temp +1
print the Sum to the user

}
