Exercise 1-4

1-4 Write a program based on the following program to print the corresponding Celsius to Fahrenheit table.

#include <stdio.h>

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

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

  fahr = lower;

  while (fahr <= upper)
  {
    celsius = 5.0/9.0 * (fahr-32.0);
    printf("%3.0f %6.1f\n", fahr, celsius);
    fahr = fahr + step;
  }

  return 0;
}

#include <stdio.h>

int main(void)

{

  float fahr, celsius;

  int lower, upper, step;

  lower = 0;

  upper = 300;

  step = 20;

  celsius = lower;

  while (celsius <= upper)

  {

    fahr = 9.0/5.0 * celsius + 32;

    printf("%3.0f %6.1f\n", celsius, fahr);

    celsius = celsius + step;

  }

  return 0;
