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 for the sort type) are all integers. Sort the numbers using the bubble sort algorithm. Do not use a global array to hold the integers; use a locally-defined array in main and pass the array to the sorting function along with the type of sort (ascending or descending). Print out the sorted numbers, one per line. Your bubble sort function must be in its own separate file. The main() function should be in a file called main.c, along with supporting functions (like for printing a usage message). This program must be written in C (not C++). Note that if you're compiling on an OS, use the gcc command, not g++. Note also that since your program is in C, your source files should have a .c extension, not .cpp or .cxx.

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 for the sort type) are all integers.
Sort the numbers using the bubble sort algorithm. Do not use a global array to hold the integers; use a locally-defined array in main and pass the array to the sorting function along with the type of sort (ascending or descending).
Print out the sorted numbers, one per line.
Your bubble sort function must be in its own separate file. The main() function should be in a file called main.c, along with supporting functions (like for printing a usage message).
This program must be written in C (not C++). Note that if you're compiling on an OS, use the gcc command, not g++. Note also that since your program is in C, your source files should have a .c extension, not .cpp or .cxx.
