invalid conversion from 'int' to 'int*' [-fpermissive] on passing array

Question

I am new to C++ language and I have no idea of pointers and their usage. I\'m facing the error \"[Error] invalid conversion from \'int\' to \'int*\' [-fpermissive]\"

Answer 1

Change the function call

cout << midd(ax, asize) << endl;

and declaration

double midd(int arr[], int size) { ... }

or go the C++ way: std::vector or std::array. For example

#include 
#include 
using namespace std;

double midd(array a) {
    int mid = a.size() / 2;
    return (a[mid] + a[mid + 1]) / 2.0;
}

int main() {
    array ax = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };
    cout << midd(ax) << endl;
}
