In C$++$ Please, I have tried following another answer here but it still says that it's wrong. Thank you. $8\mathrm{.}20$ LAB: Parsing dates

Complete main$()$ to read dates from input, one date per line. Each date's format must be as follows: March $1,1990.$ Anty date not following

that format is inoorrect and should be ignored. Use the substrof function to parse the string and extract the date. The input ends with $-1$ on

line alone. Output each correct date as: $3-1-1990.$

Ec If the input is:

March $1,1990$

April $21995$

then the output is:

$3-1-1990$

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 retumed.
