C Program for Temperature Conversion from Fahrenheit to Celsius.

K&R C Program Exercise 1-03 Problem :

Modify the temperature conversion program to print a heading above the table.

C Program :

#include <stdio.h>
int main(void) {
   float fahrenheit, celsius;
   int lower, upper, step;
   lower = 0;
   upper = 200;
   step  = 20;
   printf("  F\tC");
   printf("\n------------");
   fahrenheit = lower;
   while (fahrenheit <= upper) {
      celsius = (5.0 / 9.0) * (fahrenheit - 32.0);
      printf("\n%3.0f %6.1f", fahrenheit, celsius);
      fahrenheit = fahrenheit + step;
   }
   return 0;
}

#include <stdio.h>

int main(void) {

float fahrenheit, celsius;

int lower, upper, step;

lower = 0;

upper = 200;

step = 20;

printf(" F\tC");

printf("\n------------");

fahrenheit = lower;

while (fahrenheit <= upper) {

celsius = (5.0 / 9.0) * (fahrenheit - 32.0);

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

fahrenheit = fahrenheit + step;

}

return 0;

}
