Hi,

I have an integer array which is a mixture of characters and integer numbers (the numbers and characters could be any value - this is just an example):

Code:

int Array1[]  = {'s',250,'w',10,500,'p',15 };

I want to separate out the numbers and characters into two arrays. One of characters, and one of the integer numbers to get result:

Code:

ArrayChars[3] ...contains... {'s','w','p'}
ArrayIntNums[4] ...contains...{250,10,500,15}

The characters are commands and the numbers are data for a command. So for example {'s', 250} means "set speed to 250"

I don't even know if it is possible and I may have to store the numbers and characters in separate arrays. I think one main problem might be that some numbers and characters are interchangeable (eg 's' is also 115 and visa-versa in decimal)

Can anyone point me in the right direction?

Many Thanks

Depends. Are the odd positions in the array always letter equivalents, while the even positions are always numbers?

I may have to store the numbers and characters in separate arrays.

Makes more sense to me.

Can anyone point me in the right direction?

Thataway!

I think the best you could do is call them characters if in a certain range, and numbers otherwise.
www.asciitable.com

0x41 to 0x5A are capital letters
0x61 to 0x7A are lowercase letters
everthing else is a number.
Your call if you want to accept other things as characters.

Na migo thisaway! 

Thanks for the input PaulS.

I'll go with separate arrays.

Cheers

Thanks CrossRoads that link's really useful - I keep it for future reference. 

It is more sensible to go for separate arrays for chars and data. Then I could use other data types as well.

cheers
