What are Kotlin’s basic control flow structures?
Kotlin provides several basic control flow structures that allow developers to manage the flow of program execution based on conditions and loops.
if-else Expression: The if statement in Kotlin is an expression, meaning it returns a value. It can be used to conditionally execute blocks of code based on boolean expressions.
When Expression: Kotlin’s when expression is similar to the switch statement in Java but offers more flexibility and power. It allows developers to match a value against multiple cases and execute the corresponding block of code.
for Loop: Kotlin’s for loop iterates over ranges, arrays, collections, or any other iterable object. It simplifies iterating over elements without the need for explicit indices.
while Loop: The while loop in Kotlin executes a block of code repeatedly as long as the specified condition is true. It is suitable for situations where the number of iterations is not known beforehand.
break and continue: Kotlin supports break and continue statements within loops to control the loop’s execution flow. break terminates the loop prematurely, while continue skips the current iteration and proceeds to the next one.
These control flow structures provide the necessary mechanisms for implementing conditional logic and iterative processes in Kotlin programs.
