(a) Use typedef to define a type named Spreadsheet corresponding to a 2- dimensional array of positive or negative integers with dimensions NUMROWS and NUMCOLS, assuming NUMROWS and NUMCOLS have been defined as constants. (b) Write a complete C++ function named writeSpreadsheet that, for example, can be called by write Spreadsheet (my_array, 21, 5, "my_file.txt"); to write 21 lines of 5 integers each into a file called "my_file.txt" from a Spreadsheet named my_array. (CEITHER explain why your writeSpreadsheet function in part (b) facilitates design by contract OR write a line of code that could be added to facilitate design by contract and explain its purpose. (d) Would you consider the Spreadsheet type an aggregate data type? Explain. (a) Write a declaration for a C++ structured-record type named Counter that includes two integer fields named counter_value and counter_upper. Choose the most suitable type for fields that will hold only nonnegative integer values. (b) The counterinitialize function can be used to initialize any Counter variable to any appropriate given values for the counter value and its upper bound. The provided values should be nonnegative and the counter value should be less than its upper bound. Write an interface specification (fancy comments) that describes the counterlnitialize function in the style described (a) Use typedef to define a type named Spreadsheet corresponding to a 2- dimensional array of positive or negative integers with dimensions NUMROWS and NUMCOLS, assuming NUMROWS and NUMCOLS have been defined as constants.
