Answer 1

Answer:

void printarr(int nums[],int n)

{

   cout<<"{";//printing { before the elements.

   for(int i=0;i<n;i++) // iterating over the array.

   {

       cout<<nums[i];//printing the elements.

       if(i==n-1)//if last element then come out of the loop.

       break;

       cout<<",";//printing the comma.

   }

   cout<<"}"<<endl;//printing } at the end.

}

1 2 3 4 5

{1,2,3,4,5}

Explanation:
