additional info..
modulo sign % - using this sign the modulo sign it looks for the remainder of 2 numbers .

Example.

code:

echo 7 % 3;


output :

1

Hope this helps :D

you must use the length() method of a class String which gives you the number of character in your string. For future use IDE which helps in finding bugs in your programs.
Change line 4 to:
int i=hulk.length();

cheers

no doubt, there's so much more and it's so much easier. Kind of in the same boat!

Great tutorials. Curious as why when I try to increment a integer I get an error. But incrementing/decrementing works for variables with no problems. Please explain.

P.S. I guess it doesn't really make sense to use incrementing with a static integer, but in technical terms is there any other reason that this isn't working? What would would the syntax look like to make it work?

Hi!
First of: Great tutorials and great help! :)
Second: Is there a way to echo out the integers without the $ sign? Like in C++? There you can just echo "num1" (if your integer is calle num1).

[iTURING]

Great videos! :) But how can I actually publish it on the internet? Like how is everyone supposed to see it?

[Itosikrm]

i can't see the concatenate character of line break?
is it dot/period?

[blink]

Cool I'm the first person to watch this.

[MrMiraculus]

num1++ or num=num+1
num1-- or num=num-1

chris bro can i limit the values after decimal point ???

[cirstearazvan]

It's quite similar to C language, isn't it ?  Thanks for the video

one question what if i want to show 5+6=11
i mean not just the answer .
do i have to write normal like *echo "5+6=11" ;*
or there is another way ?

[vychanotdomhon]

hi !! i wonder  whether it is possible to echo  in the variable of string  and integer in the same statement . Please reply ! :) I am totally newbie here 

for exampe  I want to ouput 20+30 = 30 
"30" is integer and "20+30" is string .
