*Exercise 5.1 Summing reciprocals of five values

Exercise 5-1. Write a program that will read five values of type double from the keyboard
and store them in an array. Calculate the reciprocal of each value (the reciprocal of
value x is 1.0/x) and store it in a separate array. Output the values of the reciprocals and
calculate and output the sum of the reciprocals.

//Exercise 5.1 Summing reciprocals of five values
#include <stdio.h>

int main(void)
{
  const int nValues = 5;               // Number of data values
  double data[nValues];
  int i = 0;              // Stores data values
  double reciprocals[nValues];
  double sum = 0.0;                    // Stores sum of reciprocals

  printf("Enter five values separated by spaces: \n");
  for( i = 0 ; i < nValues ; ++i)
    scanf("%lf", &data[i]);

  printf("You entered the values:\n");
  for( i = 0 ; i < nValues ; ++i)
    printf("%15.2lf", data[i]);
  printf("\n");

  printf("\nThe values of the reciprocals are:\n");
  for( i = 0 ;  i < nValues ; ++i)
  {
    reciprocals[i] = 1.0/data[i];
    printf("%15.2lf", reciprocals[i]);
  }
  printf("\n\n");

  for( i = 0 ; i<nValues ; i++)
  {
    sum += reciprocals[i];              // Accumulate sum of reciprocals
    if(i > 0)
      printf(" + ");
    printf("1/%.2lf", data[i]);
  }
  printf(" = %lf\n", sum);
  return 0;
