if an array named num is dimensioned to hold 10 values in 5 rows and 2 columns, how would you store 50 in the first physical row and second physical column?
num[2] = 50;
nnum[0, 0] = 50;
num[0, 1] = 50;
num[1, 1] = 50;
num[0, 1] = 50;
if(value1 > value2)
largestOne = value1;
else
if (value1 < value2)
largestOne = value2;
