   assignment 5: Date Validate / Format 
   Date: 11/08/2016 ELLECTION DAY!!!!

  program description
     Input: Accept input for the first program via the command-line arguments. 
            Input will be the number of valid entries to be redirected from 
            the dates input file (dates.dat). A zero indicates to input all
            entries from the dates input file. Your program should validate
            (day, month & year - see page 111 for validation ideas) and skip 
            corrupt dates in the dates.dat file (see page 159 for scanning 
            ideas). This validated input will then be piped out to the 
            second program. 
            The second program will accept these validated dates in the 
            month/day/year format and convert each of them to the day, 
            abbreviated month & year format — both exhibited above. The 
            abbreviated month should consist of the first three letters of 
            the month, capitalized. These converted results will be redirected 
            to the output file (output.dat), followed by a copy of the 
            original (dates.dat) data.

     Output: Generates an output file (output.dat) that contains a 
             converted list of dates in day, abbreviated month & year 
             format (i.e. 1 JAN 1900), followed by the original list of 
             dates in month/day/year format (i.e. 1/1/1900). This output file 
             will be the result of appending the input file (dates.dat), which
             is accessed by the first program, with the result output file 
             (output.dat), generated by the second program.

  how to compile and execute:
    1.Open the terminal
        Go to the program folder that contains all the files required for 
        the program to compile including all header files(*.h). 
        Run the following command "make"

    2.Open the terminal
        Go to the program folder that contains all the files required for 
        the program to compile including all header files(*.h). 
        COMPILE: "gcc -Wall -w -lm readDate.c dateValidate.c -o validateDate"

    Program execution:
    From the terminal enter:
     “./validateDate < dates.dat [X] | ./format > output.dat"

     X: is the amount of validated dates
