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 substring 0 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 2 1995 7/15/20 December 13, 2003 -1 then the output is: 31199012132003 Use the provided GetMonthAsInt 0 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: GetMonthAs Int ("February") returns 2 and GetMonthAs Int ("7/15/20" ) returns 0. 453236.3144438.q3zqy7
