in C $10\mathrm{.}7$ 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 substring$()$ 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:

$3-1-1990$

$12-13-2003$

Use the provided GetMonthAsInt$()$ 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: GetMonthAsInt$("$February$")$ returns $2$ and GetMonthAsInt$("7/15/20")$ returns $0.$

Output is nearly correct, but whitespace differs. See highlights below.
