Consider a 2-by-3 integer array t.

Question

a) Write a declaration for t.
b) How many rows does t have?
c) How many columns does t have?
d) How many elements does t have?
e) Write the names of all the elements in row 1 of t.
f) Write the names of all the elements in column 2 of t.
g) Write a statement that sets the element of t in the first row and second column to zero.
h) Write a series of statements that initialize each element of t to zero. Do not use a loop.
i) Write a nested counter-controlled for statement that initializes each element of t to zero.
j) Write a nested range-based for statement that initializes each element of t to zero.

Answer 1

```
a) array, 2> t;
b) 2
c) 3
d 6
e) t[1][0], t[1][1], t[1][2]
f) t[0][2], t[1][2]
g) t[0][1] = 0;
h) t[0][0] = 0;
t[0][1] = 0;
t[0][2] = 0;
t[1][0] = 0;
t[1][1] = 0;
t[1][2] = 0;
i) for (int i{0}; i < 2; ++i) {
for (int j{0}; j < 3; ++j) {
t[i][j] = 0;
}
}
j) for (auto& row : t) {
j) for (auto& element : row) {
element = 0;
}
}
