Convert Int array to an integer

[Bleedz129]

Is there anyway we can make an integer array to an integer

Thank you

Yes. Can you be more specific about what you wish to do?

Of course

IF we have an integer array such as int A[3] = {1,2,3}

How do we make it int A = 123.

Thanks

may want to use stringstreams.

Remember your basic math. This is kind of the opposite of logarithm -- each element is multiplied by a power of ten.

123 = 1×10² + 2×10¹ + 3×10⁰

Another example:

7926 = 7×10³ + 9×10² + 2×10¹ + 6×10⁰

The simplest way for your array is an iterative approach:

result = 0
for each element in array, first to last:
  result *= 10
  result += element

Hope this helps.
