character code points versus plain integers

[dorkz]

if i do this:

[CODE=cpp]#include <iostream>

int main()

{
char number1 = '9' , number2 = '1' , answer ;
answer = '9' + '1'

cout << answer << endl ;
cin.get()
}[/CODE]

then the result will be: :



and if i do this :
[CODE=cpp]
#include <iostream>

int main()

{
char number1 = 9 , number2 = 1 , answer ;
answer = 9 + 1

cout << answer << endl ;
cin.get()
}[/CODE]

whats the result now?

'1' is just another notation for the Latin 1 (formerly known as ASCII) code for the
code point 49. '9' has code point value 57. So basically you're adding 49+57.

mcfaker, I mean, dorkz, did you try putting it into a compiler?

And please use code tags in the future.

[dorkz]

thanks , but you mean that in the first example with the apostrofs, the result will be : 49 + 57 = 106, and 106 is character 'j' ??? do you mean that?

I don't know what the code point value of a lower case 'j' is, but if it is 106, then yes,
that's what I mean.

kind regards,

Jos

[dorkz]

yes it is 'j'


but , by the second example , the example without the apostrofs , what is the result of this? 10?

hello? coolpeople coming to help me.

You do know how to do simple additions do you?

And if you don't want to do addition, see post #3.

[dorkz]

[dorkz]

look 9 + 1 without apostrofs is 10 anyhow?

[dorkz]

ASCII-codes use by char

please answer wirhout apostrofs, will it be 10??

[JosAH]

im in shock! but please answer, then i stop answering?ok?

Everything is answered already. '1'+'9'= 106; 1+9= 10.
