If you need to executes code block repeatedly until condition satisfies, For and while loop are used.
Let’s talk about while loop in Julia
Julia while loop examples
while loop used to execute a repeated code blocks until an condition satisfies
while conditional_statement // code block statements end
conditional_statement is an conditional expression, always returns
If value is true, It executes code block statements.
Here is an example
k = 1; while k <= 5 println(k) global k=k+1 end
Output prints values from 1 to 5.
While infinite loop:
Also, if conditional expression is true and there is no way to break the while, It is in infinite loop.
k = 1; while true println(k) end
Break and continue in while loop examples
break: used to break the loop from execution
here is an break usage in while loop
k = 1; while k<=10 println(k) if k == 3 break end global k=k+1 end
Without break, It prints the values from 1 to 10. with break, It prints 1,2,3 values
continue in while loop example: continue used to continue the loop execution by skipping the code after continue block.
k = 1; while k<=10 global k=k+1 if k % 3 != 0 continue end println(k) end
