WebA 2D array is also known as a matrix (a table of rows and columns). To create a 2D array of integers, take a look at the following example: int matrix [2] [3] = { {1, 4, 2}, {3, 6, 8} }; The first dimension represents the number of rows [2], while the second dimension represents the number of columns [3]. WebOutput. Result = 162.50. To pass an entire array to a function, only the name of the array is passed as an argument. result = calculateSum (num); However, notice the use of [] in the function definition. float calculateSum(float num []) { ... .. } This informs the compiler that you are passing a one-dimensional array to the function.
