Question

The following problems generate temperature-conversion tables, write the code for each part using the following equations that give relationships between temperatures in degrees Fahrenheit degrees Celsius degrees Kelvin and degrees Rankin: T_F = T_R - 459.67 degree R T_F = (9/5)T_C _ 32 degree F T_R = (9/5)T_K Write a program to generate a table of conversions from Fahrenheit to Celsius for values from 0 degree F to 100 degree F. Print a line in the table for each 5 degree change. Use a while loop in your solution. Write a program to generate a table of conversions from Fahrenheit to Kelvin for values from 0 degree F to 200 degree F. Allow the user to enter the increment in degrees Fahrenheit between lines. Use a do while loop in your solution. Write a program to generate a table of conversions from Celsius to Rankin. Allow the user to enter the starting temperature and increment between lines. Print 25 lines in the table. Use a for loop in your solution.

Explanation / Answer

#include <stdio.h>

int main(){
   //Tc = 5/9*(Tf - 32) eq 2
   printf("Tf Tc ");
   double tf = 0.0;
   while(tf <= 100.0){
       double tc = (tf - 32)*5/9;
       printf("%lf %lf ",tf, tc);
       tf+=5;
   }
   //Tk = 5/9 * (Tf + 459.67) from eq 1 and 3
   double increment = 5;
   tf = 0.0;
   printf("Enter the increment level for foreinheit to Kelvin conversion: eg 5 or 10 : ");
   scanf("%lf", &increment);
   printf("Tf Tk ");
   do{
       double tk = (tf + 459.67)*5/9;
       printf("%lf %lf ",tf, tk);
       tf+=increment;
   }while(tf <= 200.0);

   //Tr = Tf+459.67 = (9/5Tc + 32) + 459.67 = 9/5 * Tc + 491.67
   double tc = 0;
   printf("Enter the starting temperature for Celcius to Rankin conversion : ");
   scanf("%lf", &tc);
   printf("Enter the increment level : eg 5 or 10 : ");
   scanf("%lf", &increment);
   int index= 0;
   for(index = 0; index < 25; index++){
       double tr = 491.67 + (tc*9/5);
       printf("%lf %lf ",tc, tr);
       tc+=increment;   //Incrementing the tc
   }

   return 0;
}
