// Format Names program

// This program reads in a social security number, a first name, a

// middle name or initial, and a last name from file inData.

// The name is written to file outData in three formats:

// 1. First name, middle name, last name, and social security

// number.

// 2. last name, first name, middle name, and social

// security number

// 3. last name, first name, middle initial, and social security

// number

// 4. First name, middle initial, last name

Exercise 1: Compile and run program Name (name.cpp). Exercise 2: Change the data file to contain your name and Social Security number. Rerun the program. Explain why it was unnecessary to recompile the program. Exercise 3: Change program Name so that it reads its input from the keyboard rather than from a file. Compile and run the program, using the data that was originally on file name.dat. Run the program again with your name and Social Security number Exercise 4: Change the program that results from Exercise 3 to send its output to cout rather than a file. Compile and run the program using the data from Exercise 3 Exercise 5: Take the original program Nane, and alter it so that it prompts for and reads the input file name from the keyboard. Compile and run the program with the data originally on file name.dat. Exercise 6: Alter the program in Exercise 5 so that it prompts for and reads the output file name from the keyboard. Compile and run the program with the data originally on file name.dat. Exercise 7: Take the code that prompts for and reads the input and output file names from the keyboard and store it on a file to be used in later programs
