(TCO 6) What does the following function do?
double cal (double data [ ], int size )
{
double s = 0;
for (int i = 0; i < size; i++)
{
s += data [i];
}
return (s / size);
}
A.Returns the sum of all the value in the data. B. Does nothing because the data array does not
exist. C. Fails because the size of the array is not known. D. Returns the average of the values in
the data array.
Solution
Answer: D. Returns the average of the values in the data array.
This function takes double array and integer value as an input. double array represents
data and integer value represents size of that array. what this function does is, it will
calculate the sum of total elements in that array and while return the value it calculates
average of that total elements of that array.
