Problem 2 [Revision: malloc and other C features] Let's practice using malloc as well! Complete the following program by: 1. Declare an enum "agegroup" with 5 values: infant, children, teen, adult and elderly; 2. Declare a struct called "customer" that contains a string field "name", a integer field "memberld", and an enum agegroup field "ageGroup"; 3. Write the CreateCustomerRecord function that mallocs a new customer record and returns its reference to the caller. Be reminded that the upper/lower cases for the names are important. The framework of the program is given below. Fill it in so it will run with proper output: #include #include l/ insert struct/enum declarations typedef struct customer Customer typedef enum agegroup AgeGroup; l/ insert the CreateCustomerRecord function int main Customer "c CreateCustomerRecord John Chan",1234 adult) printfi"%s %d %dn-c-name,e->member IdeageGroup: return 0
