HELP!

1. Let a be a 2 dimensional array with 2 rows. What expression will give the correct number of elements that a can hold?

a) a.length

b) 2*a.length

c) a[0].length

d) a[1].length

e) a[0].length+a[1].length

2. Describe what will be the content of the 2D array a after the following code fragment is executed:

int r=3; // number of rows

int c=5; // number of columns

int [][] a = new int[r][c]; // create array a

// Compute a multiplication table:

int i, j;

for( i = 0; i < r; i++)

{ for( j = 0; j < c; j++)

{ a[j] = (i+1)*(j+1); // Build multiplication table

}

}

It would be greatly appreciated.

Thanks,

gp
