Arrays in C

[ube]

Hi I'm trying to pass some values in an array into a single variable in C.

For example:
a[0] = 1;
a[1] = 2;
a[2] = 3;

And I want to combine it to make 123. Can anyone help me with teh syntax?

Looks like you could use a loop and a multiplier that grows 10 times larger every iteration. Where's your attempt?

Do you mean each line of the array in the order? I assume you do, it'd be using strcat.
Something like:

/*First you need to declare a variable for the string:*/
char    string;

/*Now go to the code*/

strcat(string, a[0])
strcat(string, a[1])
strcat(string, a[2])

This would make string equal to 123.
Or something like that anyway.

The second argument to strcat isn't a single character, so that wouldn't work anyway. Also, it looks like his array is integers, so you wouldn't use strcat there.

b = (a[0] * 100) + (a[1] * 10) + a[2];

Easy as falling off a slimy log.

int sum = 0;
for(i = 0; i<arrLen; i++)
{
    sum+=sum*10+_array[i];
}
