Problem Statement
Show the syntax for a complete stoppage of a program inside a conditional.
This includes all threads/processes which are part of your program.
Explain the cleanup (or lack thereof) caused by the termination (allocated memory, database connections, open files, object finalizers/destructors, run-on-exit hooks, etc.).
Unless otherwise described, no special cleanup outside that provided by the operating system is provided.
Let's start with the solution:
Step by Step solution about How to resolve the algorithm Program termination step by step in the Kotlin programming language
This code is a simple Kotlin program that checks if a variable called problem
is true. If it is, the program exits with a non-zero exit code, which indicates to the operating system that the program encountered a problem. If problem
is not true, the program prints a message to the console and terminates normally.
Here's a breakdown of the code:
-
The
main
function is the entry point of the program. It takes an array of strings as an argument, but in this case, the argument is not used. -
The program defines a variable called
problem
and sets its value totrue
. This means that the if statement will be true. -
Inside the if statement, the
System.exit(1)
function is called. This function exits the program with a non-zero exit code. This is typically used to indicate to the operating system that the program encountered a problem. -
After the
System.exit(1)
function is called, the program will not execute any more code. This means that the lineprintln("Program terminating normally")
will not be executed.
If you run this program, you will see the following output:
Program terminating normally
This is because the program exits before the println
statement is executed.
You can change the value of problem
to false
to see the other behavior of the program. If you do this, the program will print the message Program terminating normally
and then exit with a zero exit code.
Source code in the kotlin programming language
// version 1.0.6
fun main(args: Array<String>) {
val problem = true
if (problem) System.exit(1) // non-zero code passed to OS to indicate a problem
println("Program terminating normally") // this line will not be executed
}
