Array as a whole can be used as function parameter.
for example: here we design a function to do mergesort. The prototype is as follows,
void MergeSort(int B[], int iBegin, int iEnd, int A[]);
Note; int B[] means B[] is an integer array. int A[] means A[] is an integer array
while invoking function, we use following format:
MergeSort(B, 0, SIZE, A);
here, only array names A and B are used, instead of A[] or B[].
void MergeSort(int B[], int iBegin, int iEnd, int A[])
{
…
}
Please note: array name is address, base address of the array. Hence, we can manupilate the array elements in the function.
