Declare two characters array

And take input from user in first array and at last index take slach zero (/0) similarly we take input in second array and at end /0.

And take another array and copy first array in this blank array and when we come to /0 then copy second array in blank array.

Example

• First array (this is a)


• Second array (book)


• Blank array (this is a book)
