Mapmaker |
The Cybersoft Computer Company (a leader in programming languages) has hired
you to work on a new programming language named A--
. Your task is
to work on the array mapping tasks of the language. You will take an array
reference such as x[5,6]
and map it to an actual physical address.
In preparation for doing this, you will write a program that will read in
several array declarations and references and give the physical address of each
reference. The physical address output by the program should be an integer
number in base 10.
The physical address of an array reference
is calculated from the formula
, where the constants
are calculated as specified below.
The first line of the input file contains two positive integers. The first integer specifies N, the number of arrays defined in the data file, and the second integer specifies R, the number of array references for which addresses should be calculated. The next N lines each define an array, one per line, and the following R lines contain one array reference per line for which an address should be calculated.
Each line which defines an array contains, in the following order, the name
of the array (which is limited to 10 characters), a positive integer which
specifies the base address of the array, a positive integer which specifies the
size in bytes of each array element, and D, the number of dimensions in
the array (no array will have fewer than 1 or more than 10 dimensions). This is
followed on the same line by D pairs of integers which represent the
lower and upper bounds, respectively, of dimensions
of the array.
Each line which specifies an array reference contains the name of the array
followed by the integer indexes where D is the
dimension of the array.
The output file should contain the array references and the physical addresses. There should be one array reference and physical address per line. The formatting guidelines below must be adhered to.
For each line of output:
3 4 ONE 1500 2 2 0 3 1 5 TWO 2000 4 3 1 4 0 5 5 10 THREE 3000 1 1 1 9 ONE 2 4 THREE 7 TWO 2 0 6 TWO 3 3 9
ONE[2, 4] = 1526 THREE[7] = 3006 TWO[2, 0, 6] = 2148 TWO[3, 3, 9] = 2376
