11.12 LAB: Parsing dates Complete main() to read dates from input, one date per line. Each date's format must be as follows: March 1, 1990. Any date not following that format is incorrect and should be ignored. Use the substr() function to parse the string and extract the date. The input ends with -1 on a line alone. Output each correct date as: 3-1-1990. Ex: If the input is: March 1,1990 April 21995 7/15/20 December 13,2003 1 then the output is: 31199012132003 Use the provided DateParser( function to convert a month string to an integer. If the month string is valid, an integer in the range 1 to 12 inclusive is returned, otherwise 0 is returned. Ex: DateParser ("February") returns 2 and DateParser("7/15/20") returns 0. 4500422771164+2x+57 \begin{tabular}{|l|l|l|l} LAB \\ ACTIVITY & 11.12.1: LAB: Parsing dates & 0/10 \end{tabular} Run your program as often as you'd like, before submitting for grading.
