Question

Suppose that p is a two-dimensional array with elements of type int. Which of the statements below best describes the effect of the following code?

int i = 0;

while ( i < p[ 0 ].length )
{
  p[ 0 ][ i ] = 0;
  i++;
} 

Could someone translate this to plain english for me?
I only understand that the loop will keep going when i < p[0].length but what is p[0] and what is p[0][i] ?

Answer 1

"i" equals zero
"p" is an array of arrays
while i is smaller than the "first" array's size in p
    give 0 as value to i'th element of first array in p 
    increase i by 1
