Question

Write a Prolog function (i.e, a Prolog program), called count(X,L,N), that returns in variable N the number that X appears in list L. You can assume that all values in list L are integer.

Some examples,

count(6,[9,5,3,9,14],N) should return N=0.

count(3,[9,5,3,9,14],N) should return N=1.

count(9,[9,5,3,9,14],N) should return N=2.

Using C++, A contact list is a place where you can store a specific contact with other associated information such as a phone number, email address, birthday, etc. Write a program that first takes as input an integer N that represents the number of word pairs in the list to follow. Word pairs consist of a name and a phone number (both strings). That list is followed by a name, and your program should output the phone number associated with that name. Ex: If the input is: 3 Joe 123-5432 Linda 983-4123 Frank 867-5309 Frank the output is: 867-5309 A. Create a struct in your program called ContactInfo to store a name and a phone number. B. Define and call the following function. The return value of GetPhoneNumber is the phone number associated with the provided contact name.
