Given a file, assgn2_input.txt, uploaded into the assignment folder, create a program with the following functionality. You may use the program in p. 20 of the textbook as a starting template.

• Create the following function:
  • int convert_copyfile(const char* name1, const char* name2)
  • this function should return the number of conversions made (the to THE).
• If the target file (second argument) doesnt exist, then your program should create an empty file for writing.
• If the target file (second argument) exists, then your program should exit with error message without doing anything.
• Use the combination of option flags in open() system call we covered in the class.
• Use BUFSIZE=100 to iteratively read bytes from the input file and write converted bytes into the output file. (Use while loop as in the example program.)
• While reading bytes, you should
  • Keep track of the number of occurrences of the word in the file. (Case sensitive)
• While writing bytes to the output file, you should
  • Replace any occurrence of the word with THE word.
  • Then, write back the modified contents to the output file.
• Create main() function which makes the following call:
  • Convert_copyfile(assign2_input.txt, assgn2_output.txt);
• Print out the total number of conversions made (from the to THE);
• Print out the contents of assgn2_output.txt file at the end of your program
