Question

/* data is an array of doubles. len is the number of elements in the array.
The return value should be the Average of the doubles in the data array.
The Average is defined as the average value from among the elements, e.g.
   if the data array was { 6.0, 3.0, 2.5, 20.7 }, the function should return
   the value 2.5. */
double average(double data[], int len) {
double min_val = data[0];

/* TODO: Write the code that goes here */

return Avg_val;
}

Please answer the above code in C-programming

Answer 1

This question seems wrong.

2.5 can only be returned if the function returns the minimum value because the average of the array is 8.05 and not 2.5

Here is the program for average:

#include <stdio.h>

double average(double data[], int len)
{
double Avg_val=0.0;
for(int i=0; i<len; i++)
{
Avg_val = Avg_val + data[i];
}
  
Avg_val = Avg_val/len;
return Avg_val;
  
}
int main()
{
double data[]= { 6.0, 3.0, 2.5, 20.7 };
int len = 4;
  
printf("%.2f", average(data, len));
return 0;
}

Output:

Different code should be written for the minimum value .
