c_cpp 将数组指针传递给函数

Posted 2021-05-14

#include <iostream>
using namespace std;

double getAverage(int arr[], int size)
{
  int    i, sum = 0;       
  double avg;          
  for (i = 0; i < size; ++i)
  {
    sum += *arr;
    arr++;
   }

  avg = double(sum) / size;

  return avg;
}


int main() {
	int numbers[4] = {1, 2, 3, 4};
	cout << getAverage(numbers, 4) << endl;
	return 0;
}
