Topic 5: Using Loop Constructs Flashcards
When can you omit curly braces in a loop construct?
These can be omitted when the loop body consists of a single statement.
You should use this loop when iterating over collections or arrays in a concise and readable manner. and we know that we wish to access verey element (definite iteration)
When should you use the enhanced for loop?
When should you use a do/while loop?
You should use this loop when you need to ensure a block of code is executed before evaluating the loop condition, such as in menu-driven applications or for validation and error handling.
This loop is designed for iterating over collections and arrays.
What is the purpose of the enhanced for loop?
When should you use a while loop?
You should use this loop when the number of iterations is not known in advance (indefinite iteration), such as for input validation or condition-based termination.
This is used when you know the number of iterations in advance or need to iterate over a range of values.
What is the purpose of the for loop?
When should you use a for loop?
You should use this loop when iterating over arrays or collections, or when you need to perform numeric iteration a specific number of times.
What is the purpose of the enhanced for loop?
This loop is designed for iterating over collections and arrays.
You should use this loop when you need to ensure a block of code is executed before evaluating the loop condition, such as in menu-driven applications or for validation and error handling.
When should you use a do/while loop?
What is the purpose of the while loop?
This loop is used when you need to repeat a block of code as long as a certain condition remains true.
When should you use the enhanced for loop?
You should use this loop when iterating over collections or arrays in a concise and readable manner. and we know that we wish to access verey element (definite iteration)
These can be omitted when the loop body consists of a single statement.
When can you omit curly braces in a loop construct?
What is the purpose of the do/while loop?
This loop guarantees the execution of the loop body at least once before checking the loop condition.
How are nested loops used to iterate over a rectangular or jagged array?
Each dimension of the array corresponds to a nested loop. The number of nested loops matches the dimensions of the array.
You should use this loop when iterating over arrays or collections, or when you need to perform numeric iteration a specific number of times.
When should you use a for loop?
