            arrays is pointer
  when you see x exit   
       you see n create (old one is new array[a]  new one is array[i+1])
       you see d delete arrays[i]  according to int after d
       first number is size of max arrays

and where is the error in code input is composed from int and n d x

i make a program 
   -taking input(first input must be int)
   -according to input(there is comman in input like n or d or j , i fill array with number and use memory efficiently
   -j is jumb to array[x] ( x is int coming after j in input)
