Program Trace Description You are given the following program

You are asked to trace the execution of a provided C++ program, explaining how each line in the main() function produces its output. The task involves analyzing the flow of the program, understanding how functions are called, how variables are manipulated, and how output statements generate their respective lines. Additionally, the assignment requires providing step-by-step debugger screenshots of at least five statements to show the passing and changing values during execution. This exercise emphasizes understanding function calls, control flow, variable scope, and output generation without relying heavily on external references, as the quiz is open-book but designed to test comprehension.

Paper For Above instruction

The given program comprises several functions designed to demonstrate various aspects of C++ programming, including parameter passing, loops, conditionals, array manipulation, and output statements. Its core purpose is to analyze the execution flow, especially from main(), to understand how each output line is produced via function calls and internal logic.

Starting with main(), the program begins by calling question_0 with the argument "q0\n". The function question_0 invokes s(ss), which simply outputs the string passed to it. Therefore, "q0\n" is printed first. Afterwards, a separator string ss, which contains "-———", is output by s(ss). This pattern repeats for subsequent functions: question_1, question_2, etc., each accompanied by the separator string. This design ensures clear demarcation between outputs.

Focusing on question_1, it calls f1(5,7). Inside f1, local variables a and b are compared and potentially swapped to ensure a

Subsequently, question_1 calls f2(7,6). Inside f2, it simply calls f1 with arguments a=6 and b=7, repeating similar logic as above, with swapped parameters. This chain demonstrates function nesting and parameter passing.

The subsequent sequence of question functions primarily outputs strings or calls other functions, each designed to demonstrate specific features. For instance, question_3 calls f3(), which manipulates an array and performs conditional checks and loop decrementing q. It outputs logical negations and double negations based on array values, illustrating array indexing, looping, and conditional logic. The output results depend on array initialization and the while loop that decrements q, eventually producing a series of zeros and ones based on conditions, followed by either "Great!" or "Terrific!".

In question_4, an array c is defined with characters 'M', 'I', 'A', 'M', 'I'. The loop calls f4 for each character, which checks whether the character is between 'A' and 'I'. For 'M', 'I', and 'A', this is true or false, resulting in outputting 1 or 0 accordingly. This activity demonstrates character comparisons and for-loop iteration.

Question_5 sums two integers after displaying a string; question_6 outputs a string followed by a fixed message. The main() function executes all these in sequence, displaying the generated output. Finally, it calls question_5 with parameters derived from f5, which computes the difference between two integers, illustrating arithmetic and function returns.

Through this step-by-step explanation, each output instance in main() can be traced back to its source function call, the values passed, and the internal logic. The debugger screenshots would illustrate variable states at crucial points: initial parameter values, loop counters, array indexing, and condition evaluations, providing visual clarity of execution flow.
