Study Notes
- The "if" statement is used to test if a condition has been met.
- The syntax for using "if" is "if (condition) { code to execute }".
- The curly braces can be omitted if there is only one line of code to execute.
- The condition in the parentheses must use one or more operators.
- "if/else" allows for multiple tests to be combined.
- If a test is true, the code associated with it will execute.
- "else if" can be used to add additional tests.
- "else" is the default action if no tests are true.
- "switch case" can also be used for testing multiple conditions.
- It is important to use proper syntax and indentation for readability.
