What is a data type in programming, and why is it important?
✔✔A data type specifies the kind of data that can be stored and manipulated within a program,
such as integers, strings, or floats. It is important because it defines how data is treated and
ensures correct operations and storage.
What does the term "syntax" refer to in programming languages?
✔✔Syntax refers to the set of rules and structure that defines how code must be written in a
programming language, ensuring that the code can be properly parsed and executed.
How does an `if` statement work in a program?
✔✔An `if` statement evaluates a condition; if the condition is true, the associated block of code
is executed; otherwise, the program continues without executing that block or moves to an `else`
block if provided.
What is the purpose of a `while` loop, and how does it differ from a `for` loop?
1
, ✔✔A `while` loop repeatedly executes a block of code as long as a specified condition remains
true, whereas a `for` loop iterates a block of code a specific number of times or through a range
of values.
What is the function of the `return` statement in a function?
✔✔The `return` statement terminates the execution of a function and optionally returns a value
to the calling code, providing the result of the function’s operations.
What is an input/output (I/O) operation in programming?
✔✔I/O operations involve reading data from an input source (e.g., keyboard, file) and writing
data to an output destination (e.g., screen, file), facilitating interaction with the user or other
systems.
What is a loop counter, and how is it used in programming loops?
✔✔A loop counter is a variable that keeps track of the number of iterations in a loop, often used
to control the loop’s execution and manage how many times the code block runs.
How does a `switch` statement differ from a series of `if` statements?
