C - The C Answer (2nd Edition) - Exercise 1-4

/*
Write a program to print the corresponding Celsius to Fahrenheit table.
*/

#include <stdio.h>

/* print Celsius-Fahrenheit table for celsius = 0, 20, ..., 300; floating-point
version */
main()
{
    float fahr, celsius;
    int lower, upper, step;

    lower = 0;   /* lower limit of temperature table */
    upper = 300; /* upper limit                      */
    step  = 20;  /* step size                        */

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

/* Output:

Celsius Fahr
  0   32.0
 20   68.0
 40  104.0
 60  140.0
 80  176.0
100  212.0
120  248.0
140  284.0
160  320.0
180  356.0
200  392.0
220  428.0
240  464.0
260  500.0
280  536.0
300  572.0
