I'm working on a program that determines a type of torus, volume of that torus, surface area, and cost of fabricating it/painting it based upon 2 input radii: rmajor and rminor. *The only complicated part is I can't use logical operators or comparison statements.* I am able to determine the surface area, volume, and costs related to the torus but I can't determine the manufacturing code (as shown in the print statements). The corresponding Manufacturing codes are as follows:

1. Ri: ring torus (rmajor > rminor)
2. Hn: horn torus (rmajor = rminor)
3. Sp: spindle torus. (rmajor < rminor)

How would I go about correctly printing the corresponding manufacturing code to each type of torus?

Here is my current code:

```
#include<stdio.h>
#include<math.h>
//GLOABAL DECLARATIONS

 #define COST 75.25
 #define PAINT 13.65

int main()
{
   //LOCAL DECLARATIONS

   int rmajor;
   int rminor;
   int factor1;
   int factor2;
   int factor3;
   char char1;
   char char2;
   double area;
   double volume;
   double cost;
   double paint;

   //EXECUTABLES

   printf("Please input major radius (meters): ");
   scanf("%d" , &rmajor);
   printf("Please input minor radius (meters): ");
   scanf("%d", &rminor);
   printf("\n=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=\n");

   volume = (M_PI * pow(rminor,2)) * (2*M_PI*rmajor);
   area = (4 * pow(M_PI,2) * rmajor * rminor);

   factor1 = rmajor / rminor;
   factor2 = rminor / rmajor;

   factor1 = (factor1 + 2) % (factor1 + 1);
   factor2 = (factor2 + 2) % (factor2 + 1);
   factor3 = (factor1 * rmajor) + (factor2 * rminor);
   factor3 = factor3 / (factor1 + factor2);

   char1 = (factor1 * ('R' - 'A')) + (factor2 * ('H' - 'A')) + (factor3 * ('S' - 'A'));
   char2 = (factor1 * ('i' - 'A')) + (factor2 * ('n' - 'A')) + (factor3 * ('p' - 'A'));
   //printf("\nchar1: %c\n", char1);
   //printf("char2: %c\n", char2);

   cost = COST * volume;
   paint = PAINT * area;

   printf("Manufacturing Code: %c%c\n ", 'A' + char1, 'A' + char2);
   printf("Surface Area     : %13.2f\n", area);
   printf("Volume            : %13.2f\n", volume);
   printf("=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-\n");
   printf("Cost of building torus ($): %12.2f\n", cost);
   printf("Cost of painting torus ($): %12.2f\n", paint);
   printf("=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-\n");

  return(0);
}

```

Here are some of my example outputs:

```
Please input major radius (meters): 10
Please input minor radius (meters): 5

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
Manufacturing Code: ?

```

Output 1 is supposed to be a ring torus (Ri) and Output 2 should be a horn torus (Hn). Any help is appreciated, thank you!
