Understanding Trace Tables

What is the primary purpose of using trace tables in programming?

• To execute programs faster

• To design user interfaces

• To compile code

• To understand program flow and test algorithm accuracy

When setting up a trace table, what should each variable in the program have?

• Its own row

• Its own column

• A unique identifier

• A default value

In the example program, what value is initially assigned to the variable 'total'?

• 1

• 5

• 0

• 10

What happens to the 'counter' variable at the end of each iteration of the for loop?

• It remains unchanged

• It is incremented by one

• It is reset to zero

• It is decremented by one

What is the initial value of the 'counter' variable in the for loop?

• 5

• 1

• 0

• 10

What does the trace table show when the 'total' variable is updated?

• The previous value of 'total'

• The average of all values

• The new value of 'total'

• The sum of all previous values

Why is it important to update the trace table when a variable changes?

• To simplify the code

• To reduce memory usage

• To increase the program's speed

• To keep track of the program's logic

What is the final output of the program when the user inputs the number 5?

• 15

• 120

• 25

• 5

What mathematical operation is the program performing with the input number?

• Finding the factorial

• Determining the average

• Calculating the square

• Computing the sum

How does the trace table help in understanding the program?

• By simplifying the code

• By generating random outputs

• By executing the program automatically

• By providing a visual representation of variable changes
