Fahrenheit to Celsius C Program using While loop

Program:

#include<stdio.h>
int main()
{
   float celsius, fahr ;
   int lower, upper, step ;

   lower=100, upper=300, step=50 ;
   fahr = lower ;

   while ( fahr <= upper )
   {
      celsius = (5.0/9.0) * (fahr - 32) ;

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

      fahr += step ;  // fahr = fahr + step
   }

   return 0;
}

Output:

100        37.8 
150        65.6 
200        93.3
