$"$Hi Can you give meth code for this question.

Write a C$++$ program that maintains information about blood donors in a blood bank. The program should include the following functions $1-$ Function asks the user to enter all the details of a donor and then returns the data to main. The function should return data using reference parameters. The collected information should include the following: blood donor card number, $//$ long name of donor $//$ String blood group$//$ the possible blood groups are A$+,$ A$-,$ B$+,$ B$-,$ O$+,$ O$-,$ AB$+,$ AB$-.$ mobile phone number $//$String

$2-$ Function takes a string as parameter and returns true if it is a valid group and false if not. The only possible blood groups are A$+,$ A$-,$ B$+,$ B$-,$ O$+,$ O$-,$ AB$+,$ AB$-.3-$ Function prints the details $($blood donor card number, name, blood group, and mobile phone number$)$ of the donor. $4-$ Function displays the following menu: $1-$ New blood donor $2-$ Print Blood Donor Information $3-$ Print number of donors based on blood group $4-$ Exit $5-$ Main function includes at least the following d XA$13$ efinitions and steps a$.$ An array of type string to hold blood groups. b$.$ An array of type integer to hold number of donors in each blood group. c$.$ Display menu continuously until user enter $4$ to exit program. d$.$ When user select $1$ from the menu, first function will be called and the array that count donors based on blood group should be increased by $1.$ e$.$ When user select $2$ from the menu, second function will be called, and the current entered donor information should be printed. f$.$ When user select $3$ from the menu, ask the user to enter a valid blood group. The program displays the number of donors donated based on entered blood group.

$6-$ Remember to use meaningful names when you define variables and functions."
