7.3.4 Complete the trace table for a given flowchart;

Trace Table:

           A trace table is a tabular representation that shows the values of variables at each step of a program's execution. It helps in tracking the changes in variable values and understanding the flow of control in a program. 

However, a flowchart represents the flow of a program using various symbols and arrows, but it does not provide a direct way to create a trace table. To create a trace table for a flowchart, you will need to convert the flowchart into a structured program, such as pseudocode or a programming language, and then execute the program step-by-step while recording the variable values in the trace table. 

To fill in the trace table, you would need to execute the program step-by-step, update the variable values at each step, and record the values in the corresponding table cells. The process continues until the program execution is complete. Please note that the trace table will vary depending on the specific flowchart or program you are working with.

Flowchart:

Trace Table:

Step	X	Y	Z
1.
2.	7
3.	7	4
4.			3

Steps:

1.    First, the user will input the value of X; let’s suppose it is 7 then the variable X becomes 7.

2.    Next, the user will enter the value of Y; let’s suppose it is 4 then the variable Y becomes 4.

3.    Now, we have to evaluate the conditions:

X>Y = YES! Then Z= X-Y

7>4 = YES! Then Z=7-4 = 3

Final Output = 3
