Exercise 1-15

Exercise 1-15  Rewrite this program to use a function for conversion.

#include <stdio.h>

int main(void)
{
  int fahr, celsius;
  int lower, upper, step;

  lower = 0;
  upper = 300;
  step = 20;

  fahr = lower;
  while (fahr <= upper)
  {
    celsius = 5 * (fahr-32) / 9;
    printf("%d\t%d\n", fahr, celsius);
    fahr = fahr + step;
  }
  return 0;
}

#include <stdio.h>

int convert(int fahr)

{

  return 5 * (fahr-32) / 9;

}

int main(void)

{

  int fahr, celsius;

  int lower, upper, step;

  lower = 0;

  upper = 300;

  step = 20;

  fahr = lower;

  while (fahr <= upper)

  {

    celsius = convert(fahr);

    printf("%d\t%d\n", fahr, celsius);

    fahr = fahr + step;

  }

  return 0;

}
