What is a trace table in Computer Science?
A trace table is a strategy employed to test algorithms, to ensure that no mistakes happen when the algorithm undergoes processing. The trace table... See full answer below. Our experts can answer your tough homework and study questions.
Are there any common mistakes when completing a trace table?
There are some common mistakes that can occur when completing trace tables, even if the person completing the table has fully understood the algorithm. Two of these common mistakes are outlined below, and both provide examples based on the linear search algorithm with an input of 16.
How many columns are in a trace table?
The trace table completed in step 5 contains 4 columns, and the key factor is that all four columns show the values changing in the correct way. The exact placement of the rows and cells is not always fixed, and so there can be different layouts that are still correct, and it may suit different people to complete trace tables with different styles.
How to keep track of multiple variables in a trace table?
Although the algorithm above only contains one variable, trace tables can keep track of multiple variables by using additional columns. The algorithm below is an extension of the algorithm above, and this time the program will also keep track of how many times the while loop has repeated. In this example the user enters an input of 16.
