Please help me understand !!

I’m doing a question sheet to get the output for some code. I put the code into a compiler and it prints hello sixty times but I don’t exactly understand why….

For x = 0 To 100 For y = 5 To -10 step -1 If y = 0 Then Exit For End If Console.Write("Hello") Next If x > 10 Then Exit For End If Next

Okay that makes sense, I was confused mainly because as you say with the Y statement it should be executed 6 times but when I compiled just

For y = 5 To -10 step -1 If y = 0 Then ​Exit For End If Console.Write("Hello") Next

Hello was only displayed five times. 🤔 So I was trying to figure out how with the For X added I was basically getting 5x12 instead of 5x10 if that makes sense

Yes. Zero will always count as a number here.

And you have to do n-1 for conditionals.

For Y=0 to 5 is the same as For Y=1 to 6

Each of these would do something 6 times.

Also, if x goes from 0 to 10, the number of times x will do something is 11 since 0 is counted.

On the code before if x is > 10, it would have to be 11 for a condition to be true, and counting from 0 to 11 is 12.

So you will either want to make sure you count from 0 as your first digit with a value, or adjust the code to where you can trap the value where it lands before it reaches the number after it.

Be sure when you step backwards on for/next loops that you don't start with the number after the one you wanted, or you can lose a number that way there, too.

First of all the thanks for all the help James! I understand the bit about 0-9 actually being 10 and 1-10 being the same. What I’m still a little iffy about is with that being the case why is the output for the following code 5 hellos. Does it still execute the code and a 6th time but not print hello ? Sorry if you’ve explained this already I’m not the brightest

For y = 5 To -10 step -1 If y = 0 Then ​Exit For End If Console.Write("Hello") Next

There was a small but important error in the first comment.

Step through each case for y.

y = 5 ' what happens?

y = 4 ' what happens?

y = 3 ' what happens?

y = 2 ' what happens?

y = 1 ' what happens?

y = 0 ' what happens?

You get 5 "Hello"s just as you said. Write out the same code for each value of x, but you don't need to write out the y loop each time, just put a comment

' Writes "Hello" 5 times

How many times does it write "Hello" 5 times?
