50: ***(Syntax)*** Switch Statement

Switch Statement

Syntax:

switch (expression)
{
case /* constant-expression */:
    /* code */
    break;

default:
    break;
}

Important points: 

  1. You cannot add inequalities like percentage < 80 in the case of switch statement.
  2. You can use ranges in case like: 
    • '0' ... '9'
    • 'a' ... 'z'
    • 'A' ... 'Z'
  3. If there is same output for various cases, you cannot do:
    • switch (alpha)
          {
          case 'A' || 'a' || 'E' || 'r' || 'I' || 'i' || 'O' || 'o' || 'U' || 'u':
              cout << "This is a vowel";
              break;
         
          default:
              break;
          }
  4. If there is same output for various cases, you can do:
    •     switch (alpha)
          {
          case 'A':
          case 'a':
          case 'E':
          case 'e':
          case 'I':
          case 'i':
          case 'O':
          case 'o':
          case 'U':
          case 'u':
              cout << "This is a vowel";
              break;
         
          default:
              break;
          }

221: // In Task 2, we discussed multilevel inheritance with parameterized constructors for Student, UndergraduateStudent, and GraduateStudent classes in a university management system. Can you explain the advantages of using multilevel inheritance with specific details about the functions and data members in these classes? How were the parameterized constructors (e.g., setting student name, age, and ID) used to ensure that each class in the hierarchy correctly initializes its properties, such as creating an UndergraduateStudent named "John," aged 20, with a student ID of 12345
