Question
Predict the output of the following pseudo-code
Integer x = 1, y = 2, z = 3
x = y + z
z = x – y
z = z + x
z = y + z
x = y + z
Print x, y, z
1 2 3 4 6 8 5 12 10
Solution
The pseudo-code provided is a sequence of mathematical operations and assignments to the variables x, y, and z. Let's go through it step by step:
-
Integer x = 1, y = 2, z = 3: This initializes the variables x, y, and z with the values 1, 2, and 3 respectively.
-
x = y + z: This adds the current values of y and z (2 + 3), and assigns the result to x. So, x now equals 5.
-
z = x - y: This subtracts the current value of y from the current value of x (5 - 2), and assigns the result to z. So, z now equals 3.
-
z = z + x: This adds the current values of z and x (3 + 5), and assigns the result to z. So, z now equals 8.
-
z = y + z: This adds the current values of y and z (2 + 8), and assigns the result to z. So, z now equals 10.
-
y = y + z: This adds the current values of y and z (2 + 10), and assigns the result to y. So, y now equals 12.
-
Print x, y, z: This prints the current values of x, y, and z, which are 5, 12, and 10 respectively.
So, the output of the pseudo-code would be: 5 12 10
