Case Statements
A case statement is a control flow mechanism that allows a program to execute different code blocks based on the value of a single variable. This variable, known as a "case number" or "switch case", is compared to predefined values, and the corresponding code block is executed.
Example:
c
enum days {
MONDAY,
TUESDAY,
WEDNESDAY,
THURSDAY,
FRIDAY,
SATURDAY,
SUNDAY
};
days current_day = MONDAY;
switch (current_day) {
case MONDAY:
printf("It's Monday!\n");
break;
case TUESDAY:
printf("It's Tuesday!\n");
break;
// Similar case statements for other days
default:
printf("Invalid day!\n");
}
Benefits of Using Case Statements:
Improved code readability: By using a clear switch statement, you can organize your code and make it easier to understand.
Reduced code duplication: Case statements allow you to handle multiple similar situations with a single code block.
Enhanced code maintainability: Changes to a single case block will affect only the code associated with that case.
Additional Notes:
Case statements are commonly used in switch statements.
The default case is optional, and if left empty, it will handle any values not covered by other cases.
You can use multiple case values within a single enum using an enum definition
