Re: [Dev-C++] calculating Celsius to Fahrenheit

Try this. Yout close:
#include <math.h> 
#include <stdlib.h> 
#include <stdio.h> 

float calc(float); 

int main() 
{ 
         float c, c1; 
         int fahr, cnt=0; 
         
             printf("Fahrenheit:  Fahrenheit:    \n"); 
 //            scanf("%d", &fahr); 

         for (fahr=0; fahr<=212; fahr++) 
           { 
             c = calc(fahr++);
             c1 = calc(fahr);
 //            printf("%2f", 10,3, c, -c); 
              printf("%10.3f  %10.3f \n", c, c1);
            if (cnt++ == 21)
            {
              system("pause");
              cnt = 0;
              printf("Fahrenheit:  Fahrenheit:    \n");
            }    
           } 
         
      system("PAUSE"); 
      return 0; 
} 
float calc(float fahr) 
{ 
  float cels = 5.0 / 9.0 * (fahr - 32); 
  return cels; 
  
}

I am attempting to write a program the convert integer Fahrenheit
temperature from 0 to 212 degrees to floating point Celsius temperature
with 3 digits of precision.
The output should be in two right-justified columns of 10 characters each
and the Celsius temp should be preceded by a sign for positive and
negative.
Any suggestions.
