One circular array is given (means the memory allocation takes place like a circular fashion) dimension (9X7) .starting address is 3000.find the address of (2, 3)

• @krishnamurthy: how is it 3018? what is the formula for circular array?
• 11 years agoHelpfull: Yes(4) No(4)
• the address of (2,3) is 3018
• 12 years agoHelpfull: Yes(3) No(16)
• starting address is 3000
  every element takes 2 bytes
  total elements before (2*3)=9*1+2
  9*1-from first rows , 9 elements in each row
  
  so , (2*3) is 12th element of given array
  1) 3000 -->(1,1)
  2) 3002 -->(1,2)
  3) 3004 -->(1,3)
  4) 3006 -->(1,4)
  5) 3008 -->(1,5)
  6) 3010 -->(1,6)
  7) 3012 -->(1,7)
  8) 3014 -->(1,8)
  9) 3016 -->(1,9)
  10) 3018 -->(2,1)
  11) 3020 -->(2,2)
  12) 3022 -->(2,3)...............Answer
  
  formula to calculate
  =baseAddress+sizeOfDataType*((rowCountCurr-1*columnCount)+columncountCurr-1)
  =3000+2((2-1)*9 +(3-1))
  =3000+2(9+2)
  =3022
  ...........answer

• it's a 9x7 int array so it reqiure a 126 bytes for storing.b'ze integer value need 2 byes of memory allocation .and starting add is 3000so starting add of 2x3 will be 3012.
