add number together (not addition)

Hi!

I wonder how can I put two or more number together, like if I have:

int t = 1;
int p = 2;
int h;

h = t + p

Than "h" will be equals 3, but I will it to be 12. How can I do that?

Thanks!

It would be interesting to know where the 2 numbers come from and why you want to put them together. Once "put together" what are you going to do with the result ?

convert to strings, concatenate the strings, convert to integer?

What do you want for 0+0? 0 or 00 ?

Are you parsing a serial stream? perhaps you want parseInt()?

HansDia:

int t = 1;

int p = 2;
int h;

h = t + p

This seems to me a good example where meaningful variable names would help. For example with

int tensDigit = 1;
int unitsDigit = 2;
int combinedValue;

I doubt if you would have attempted

combinedValue = tensDigit + unitsDigit;

...R

Yes I want 1+1=11, not 2

I just thought that was a solution to make passcode with a keypad :smiley:

It is as long as the variables that you are dealing with are actually numbers and not ASCII representations of numbers. Have you got any actual code that uses a keypad to input numbers ?
