[RESOLVED] Reversing an array using pointers
I have this program that makes and populates an array. Then it is sent to a function called reverse, which reverses the order in the array. The compiler keeps giving errors. I'm not quite sure why.
CODE
Code:
void reverse(int* array, int size) {
for (int i = 0; i < size/2; i++) {
int temp = array[i];
array[i] = array[size-i];
array[size-i] = temp;
} // end of for loop
} // end of reverse
int main( int argc, char** argv ) {
int array[8];
// get and print size of the array
int size = sizeof(array) / sizeof(array[0]);
printf("Size is %d\n", size);
// populate array
for (int i = 0; i < size; i++) {
array[i] = i;
} // end of for loop
// display array before reversing
for (int i = 0; i < size; i++) {
printf("%d ", array[i]);
} // end of for loop
// new line
printf("\n");
// reverse the array
reverse(&array, size);
// display the array again after reversing
for (int i = 0;i < size; i++) {
printf("%d ", array[i]);
} // end of for loop
} // end of main
It keeps giving me this error
main.cc:17:14: error: indirection requires pointer operand ('int' invalid)
int temp = *array[i];

main.cc:18:3: error: indirection requires pointer operand ('int' invalid)

Re: Reversing an array using pointers
Code:
int temp = *array[i];
Have you fixed the errors because this line from the error list is different from the line in the code? The line in the code is
Code:
int temp = array[i];
which seems OK. Same for the other errors.
