return avg;

}

Now, let us call the above function as follows:

#include <stdio.h>

/* function declaration */

double getAverage(int arr[], int size);

int main ()
{

/* an int array with 5 elements */
int balance[5] = {1000, 2, 3, 17, 50};

double avg;

/* pass pointer to the array as an argument */
avg = getAverage( balance, 5 ) ;

/* output the returned value */

printf( "Average value is: %f ", avg );

return 0;
}

When the above code is compiled together and executed, it produces the following result:
Average value is: 214.400000

As you can see, the length of the array doesn't matter as far as the function is concerned
because C performs no bounds checking for formal parameters.

Return Array from a Function
C programming does not allow to return an entire array as an argument to a function.
However, you can return a pointer to an array by specifying the array's name without an index.
