int array..

[cvogt61457]

If your talking about a string reprsentation of an integer value, then you
would have this for a "112"

char myString[size];
myString[0] = 0x31  // "1"
myString[1] = 0x31  // "1"
myString[2] = 0x32  // "2"
myString[3] = 0x00  // null terminator

String data is actually stored with the least significate byte in the lowest
byte in storage. The start of the string is on the left side.

However, since you are working in C++, I would use std:string. It makes
working with strings very easy. It does all the string managment.
