What items are considered to comprise the state of a process?
What will be an ideal response?
The contents of the address space of a process and the values of the registers in use by that process together constitute the state of the process. This includes the PC and stack pointer values and may additionally include scheduling properties, like priority and arrival time.

Write a program that checks a text file for several formatting and punctuation matters. The program asks for the names of both an input file and an output file. It then copies all the text from the input file to the output file, but with the following two changes: (1) Any string of two or more blank characters is replaced by a single blank; (2) all sentences start with an uppercase letter. All sentences after the first one begin after either a period, a question mark, or an exclamation mark that is followed by one or more whitespace characters.
This project is deceptively simple. The problem statement is clear enough, with only a couple ambiguities to clarify. The solution shown here assumes that there is at least one line in the file to process and keeps all tabs and newlines unless they precede the first word on the first line. A helper method processes the first part of the first line to remove all leading white space and capitalize the first letter. After that, main simply reads one line of text at a time until it gets a null string, and uses another helper method to process the remaining text. This helper method is where most of the work is done: It processes each line, character by character, and uses flags to control the processing; to print only one space when there more than one in sequence, and to capitalize the first word in each sentence. Notice how the helper method to convert a character to upper case is written. The code first checks to see if the character is a lower case letter, and, if it is, it does integer arithmetic to convert the ASCII lower case code to the ASCII upper case code. A check of an ASCII chart will show that the upper case codes are 32 less than those for lower case. After doing the subtraction it is necessary to cast the integer result back to char to match the method’s return type, char.
