Lets start with the easier of the two options. Converting a char array to a string can be done by looping through the array and adding each character to the end of the string.

 

A simple way to adding a character to the end of a string is to make a string equal to itself concatenated with the character.

str = str + chr// examplestr = '' // str is currently emptystr = str + 'h' // str now equals hstr = str + 'i' // str now equals hi

With that info you can try to figure the rest out yourself.
