Refer to the following buggy function definition which will be used in the next two
questions
/**
* Requires: size > 0 and size <= number of elements of grid
* Modifies: nothing
* Effects: counts the number of capital ‘A’ characters
* in grid for the first size number of elements
* /
int countAs(char grid[], int size) {
int count = 0;
for (int i = 0; i <= size; i++) {
if (grid[i] == ,A’) {
count++;
)
)
return count;
)

B. i = size
C. i == size
D. i != size
E. Both A and C
- Given the following declaration, which call(s) to countAs
