Describe the key differences between the code found in a sequence structure and the code found in an if-statement structure. Answer:

Write a short example that uses the IF, ELSE, and ENDIF directives.

C++   enum Major {COMPUTER_SCIENCE,             COMPUTER_SECURITY_INFO_ASSURANCE,             CYBER_SECURITY,             ELECTRICAL_ENGINEERING,             OTHER};   struct Name {     string  first;     string  last;     char    middleInitial; };   struct StudentRecord {     Name    studentName;     Major   major;     string  email; };   StudentRecord student12;     Suppose you are student12. Show the C++ statements used to fill in all of your information for your StudentRecord.       Show how would you assign the third letter from the email field to a local char variable called myChar.
