The following 2D array stores prices of meals for 5 days.
It has 3
rows and 5 columns.
double[][] prices
={
{4.00 , 4.50 , 5.95 , 0 , 1.95} ,
{ 0 , 12.50, 3.50 , 0
, 0
},
{5.00 , 19.95,29.50, 0 ,
10.00}
};
Write a method that accepts an int as a parameter - 0, 1, or 2 - and adds up the prices in that row and calculates the average. It should return the average price of that row.
public double rowAverage( int row )
{
double sum = 0;
for(int c = 0; c < 5; c = c+1)
{
sum = sum + prices[row][c] ;
}
double average = sum / 5;
return average;
}
