problems switching arrays

Im trying to switch the values of 2 arrays, but the output is completely wrong.

Code:

#include <iostream>

using namespace std;

void test(int a[], int b[], int antal)
{
int c =0;    

for (int i =0; i <= antal; i++)
    {
    c = a[i];
    a[i] = b[i];
    b[i] = c;
    } 
}

int main()
{
int a[1, 9, 8, 6], b[5, 5, 5, 5], antal =4;

      for(int i =0; i < 4; i++)
      cout << a[i];
      
      cout << endl;
      
      for(int i =0; i < 4; i++)
      cout << b[i];
      
      test (a, b, 4);
      
      for(int i =0; i < 4; i++)
      cout << a[i];
      
      cout << endl;
      
      for(int i =0; i < 4; i++)
      cout << b[i];

          return 0;
}

Can anyone help me see where the error lies?

Code:

a[1, 9, 8, 6], b[5, 5, 5, 5]

Never seen that one before.

>for (int i =0; i <= antal; i++)
Here you're going one past the end of the array. So:

Code:

for (int i =0; i < antal; i++)

>int main()
>{
>int a[1, 9, 8, 6], b[5, 5, 5, 5], antal =4;

The proper way to initialize arrays is:

Code:

int main()
{
   const int antal = 4;
   int a[antal] = {1, 9, 8, 6}, b[antal] = {5, 5, 5, 5};

psh, that's right. It's been a while

Thanks for the help
