Question 1:Are the variables a and b used in the function main the same a and b variables that are used in the function swap in the program in Step 1? Explain your answer.

Question 2:Were the values stored in the variables a and b in the function main swapped after the execution of the function swap in the program in Step 1? Explain your observations.
