Question

Write a program that will ask for a desired temperature and it shifts the conditions in the Fig. shown below. - The program will ask for the room temperature and for the desired temperature. - If desired temperature is less than 2.5 degrees from room temperature (higher or lower), then do not turn heating or cooling on. - If desired temperature is 2.5 degrees or greater from room temperature (higher or lower), then set either the cooling or the heating to the proper state according to the diagram below. - Display temperature, AC state, and Heater state. Repeat the above steps three times. Program sample run is on the page below.

Writing a program in C using CodeBlocks but I cannot seem to get this right. I keep getting weird outputs for my high, med, low.

Any help would be greatly appreciated. Code is provided in link.

Answer 1

/*

program to decide the level of cooling or heating required

input - room and desired temprature as float

output - heating or cooling level

*/

#include <stdio.h>

int main() {
   float room = 0, desired = 0, diff = 0;
   int coolingLevel = 0, heatingLevel = 0;
   printf("\nPlease enter the room Temprature");
   scanf("%f",&room);
  
   printf("\nPlease enter the desired Temprature");
   scanf("%f",&desired);
  
   diff = (room>desired?room-desired:desired-room);
  
   if(diff > 2.5)
   {
     
   if (room > 75.1 && room < 85) //Else if ladder to decide the level of cooling or heating.... Change condition if required.
   coolingLevel = 1;
  
   else if (room > 85.1 && room < 95)
   coolingLevel = 2;
  
   else if (room > 95.1)
   coolingLevel = 3;

   else if (room > 60 && room < 69.99)
   heatingLevel = 1;

   else if (room > 50 && room < 59.99)
   heatingLevel = 2;

   else if (room <49.99)
   heatingLevel = 3;

  
   }
   printf("\nprintf cooling = %d",coolingLevel);
   printf("\nprintf heating = %d",heatingLevel);
   return 0;
}
