new language with a block structured syntax similar to Algol 60 uses either pass-by-reference or pass-by-value as a parameter passing mechanism, but you don’t know which. Design a test program you can use to find out which parameter passing method it uses and explain how the results of your program will enable you to detect the parameter passing mechanism

Why do modern programming languages need to support both value and reference passing? When deciding between these two alternatives, why is it so difficult to choose only one? Your solution should address both the positives of having both and the drawbacks of having either alone.

Write a C program which behaves as follows: If there are no command-line arguments at all when the program is run, the program should print out instructions on its use (a "usage message"). There should be one common usage message (consider a method/function for printing the usage message) for any type of usage error. The program will accept an A or D as the second command line argument (after the program name). This letter will tell you whether the bubble sort should sort in ascending or descending fashion. Anything other than A or D in that position should display the usage message and terminate the program. The program will be able to accept up to 32 numbers (integers) on the command line. If there are more than 32 numbers on the command line, or no numbers at all, the program should print out the usage message and exit with a non-zero value from main. This means 32 values not including the program name (argv[0]) and sort type. You may assume that the command line arguments (except…
