1. We discussed using the expression sizeof(a) / sizeof(a[0] to calculate the number of elements in an array. The expression sizeof(a) / sizeof(t) where t is the type of a's elements would also work, but it's considered an inferior technique. Why?

3. Write a declaration of an array named weekend containing seven bool values. Include an initialize that makes the first and last values true; all other values should be false.

6. Calculators, watches, and other electronic devices often rely on 7 segment displays for numerical output. To form a digit, such devices turn on some of the seven segments while leaving others off.

   Here's what the array might look like, with each row representing one digit:

const int segments[10][7] = {{1, 1, 1, 1, 1, 1, 0}, ...};

I've given you the first row of the initializer, fill in the rest.

10. Write a declaration for an 8x8 char array named chess_board. Include an initializer that puts the following data into the array, one character per array element:

omitted]

> 11. Write a program fragment that declares an 8x8 `char` array named `checker_board` and then uses a loop to store the following data into the array (one character per array element).
