Question

Date Conversion (C program) Write a program that accepts a date in International Date Format (yyyy mm dd) from the command line and converts it to an American Date Fromat, where the name of the month is displayed. If three arguments are not entered into the program, or the arguments are not numbers, an error message should be displayed. (must contain) Specifications: Store the month names in an array that contains pointers to strings. Use argc and argv as inputs to the main program. argv can be declared as a character pointer array or a character pointer to a pointer (via Netbeans). Use of the atoi() function (Ascii TO Integer) will be extremely useful.

output:

Please enter an ISO Date into the program (yyyy mm dd)

Input: 201x 33 s *if not in correct yyyy mm dd prompt to reenter

Output:

Please enter an ISO Date into the program (yyyy mm dd)

Input: 2011 11 24

Output: Date: November 24, 2011
