      Because of the way 2D array contents are specified in C++, the first index refers to the row (y coordinate) and the second index corresponds to the column (x coordinate). This is a little different than normal! Usually we would use the first index for x and the second index for y. If we weren’t hard-coding the array as shown above, we

      number (element) in an array: y = sin (x) This is an e cient way to do calculations in Python, but sometimes we need to do something more complicated on each element separately. The main reason is if elements in the array depend on each other. If we do an array operation then each number in the array is treated separately.

      2D arrays • So far, we have been working with one dimensional arrays (e.g. array([1,2,3,4,5,…]) • With “matching” 1D arrays for x and y we can plot 2D data- such as position vs time. Each “data point” contains two pieces of information: x, and y (or time and position). • A 2D array allows us to plot 3D data points- x,y,z. For ...

      Each row in a two-dimensional array is itself an array. Thus, the rows can have different lengths. If you don’t know the values in a raged array in advance, but know the sizes, say the same as before, you can create a ragged array using the syntax that follows: int [][] triangleArray = new int[5][]; triangleArray[0] = new int[5];
