Suppose an array of integers has been declared using the declaration

int num[50];

Next, x integers are stored in this array (where x is no larger than 50). The array is to be passed to a function sum which is to add up the x integers stored in the array. What should you be passing to the function sum?

Suppose a function sum has been defined as follows:

int sum(int n, int array[])
{
           int i;
           int result = 0;
           for (i=0; i<n; i++)
             result += array[i];
           return(result);
}

Suppose furthermore that in your main function an array num has been declared and initialized with the following:

int num[]={4,2,7,5,8,9,4,2,4,6};

What is the correct function call of sum(), using this array?
