MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Trace tables are used to allow programmers to trace the value of variables as each line of code is executed. The values of the variables are displayed in a table and assist the programmer in identifying any potential errors.

Detailed explanation-2: -A trace table is a technique used to test an algorithm and predict step by step how the computer will run the algorithm. It can be used to understand or predict what an algorithm is doing and to identify potential logic errors (when the program compiles but does not produce the expected output).

Detailed explanation-3: -Trace tables are used when performing a dry-run of an algorithm. This could be an algorithm expressed as a flowchart or pseudocode. Trace tables record the outputs for a given set of data, allowing the user to compare these to the expected results.

Detailed explanation-4: -The table usually takes the form of a multi-column, multi-row table; With each column showing a variable, and each row showing each number input into the algorithm and the subsequent values of the variables. Trace tables are typically used in schools and colleges when teaching students how to program.

Detailed explanation-5: -Trace table-a technique used to test algorithms to make sure that no logical errors occur. Hand tracing or ‘dry running’ allows you to use a trace table to. see what code will do before you have to run it.
