Chapter 1: Problem 30

Are programs expressed as English statements. What would each display on the screen if they were actual programs? The variable x starts with the value 0. The variable y starts with the value 5. Add 1 to x. Add 1 to y. Add x and y, and store the result in y. Display the value in y on the screen.

Short Answer

Expert verified
Answer: The final value of y is 7, and the output displayed on the screen would also be 7.

Step by step solution

01

Initialize Variables

Given: The variable x starts with the value 0 and the variable y starts with the value 5. So, we have x = 0 and y = 5.
02

Adding 1 to x

Add 1 to the value of x. Now, x = 0 + 1 = 1.
03

Adding 1 to y

Add 1 to the value of y. Now, y = 5 + 1 = 6.
04

Adding x and y

Add the value of x to the value of y and store the result in y. Now, y = 1 (value of x) + 6 (current value of y) = 7.
05

Display the value of y

Finally, display the value in y on the screen. If this were an actual program, the output displayed on the screen would be the current value of y, which is 7.
