To do Code a function computeSum() that computes the sum of arr2D. Here function needs to traverse the array one element at a time. Note that the important aspect here is the declaration of the function. 2.1 how should the function be declared (what are the parameters)? Note, that you have to pass to the function a 2D array. Which dimension of the array do you have to specify? Do you have to provide any other parameter? Prototype int computeSum(float arr[][6]); or int computeSum(float arr[3][6]); Note that the latter one does not provide the compiler with more information than the first one. The importance of the declaration here is to provide the compiler with enough knowledge on how to progress when manipulating the sub-arrays. For example, the statement arr[2][O] = 2.1; requires the system with information on the second dimension in order to compute the memory location of arr[2][0]. The other parameter that must be specified is the size of the first dimension. Namely, how many "groupings" of 6 float are passed to the function. Therefore the function prototype should be int computeSum(float arr[][6], int sizep1); input: arr the 2D array sizeD1 - the size of the first dimension
