Study Notes
Control Statements
- Conditional Control statements: Used to control the flow of execution based on conditions
- if(condition): Executes a block of code if the condition is true
- if-else: Executes one block if the condition is true and another block if it's false
- if-else-if ladder:Allows multiple conditions to be checked sequentially.
- switch(): Allows multiple options based on the value of an expression.
- switch(variable/expression)
Loops
- Loops execute a block of code repeatedly until a condition is met
- while: The condition is checked at the beginning of each iteration.
- while(condition): Executes a block of code while the condition is true
- do-while: The condition is checked at the end of each iteration.
- do{code;} while(condition); - Ensures the code runs at least once.
- for: Used for a specific number of iterations.
- for(initialization;condition;update): Executes a block of code a set number of times -Initialization: executed once before the loop begins -Condition: tested before each iteration -Update/Increment: executed after each iteration.
Jump Statements
- break: Used to exit a loop or switch statement prematurely.
- continue: Skips the current iteration of a loop and proceeds to the next.
- goto: Transfers control to a labeled statement within the code.
Conditional Statements Considerations
- Unreachable Code: Code that will never be executed because a prior condition always evaluates to true/false.
- Case Values: Case labels within a switch statement must be unique and constant expressions (e.g., integers, characters).
- Duplicate Case Labels: Not allowed in a switch statement
- Valid Expression Choices in Switch: The expression in a switch statement must be a value (int, char, or enumerated type)
General Notes
- Indentation: Crucial for code readability and correct execution; especially in loops and conditional statements.
- Comments: Documenting code enhances understanding and maintainability.
- Data Types: Variables must have appropriate data types that match the operation you are performing (int, float, etc.)
