Question

This code should be in C please!!

Your file should meet the following criteria:

• Function prototype and implementation for a calculateDivisors function that takes in an integer parameter, calculates the sum of its divisors, and returns that sum (as an integer value)

• A structure that represents what is represented on each line of output, e.g.,

o Line number

o Sum of the divisors for that line number

o Character array containing “Perfect”, “Deficient”, or “Abundant”

• Pointer declared within the main that will be used to point to an area of memory containing a collection of these structs

• Dynamically allocated memory for the number of structs necessary

• You will assign values to each struct via the pointer

• A loop that goes from X to Y, where X and Y are the numbers inputted by the user at the command line argument

o Note: because the user is entering input here, you will need to check for reasonableness:

▪ The value of X must be greater than or equal to 2

▪ The value of Y must be greater than the value of X

▪ If either one of the above conditions are not met, you should display an error and reprompt.

• The user also specifies the character used for the histogram, which is simply the sum of divisors excluding the original number.

• The line number column uses a column width of 4; the status of divisors is in a column of width 10.

Sample Output:

Prompt % ./lab12.out 15 19 ‘|'

15 is Deficient |||||||||

16 is Deficient |||||||||||||||

17 is Deficient |

18 is Abundant |||||||||||||||||||||

19 is Deficient |

COde:

#include<stdio.h>
#include<stdlib.h>

struct info{
   int lineNo;
   int sum;
   char *msg;
};

int sumOfDivisors(int num)
{
   int i, sum = 0;

   for(i = 1; i < num ; i++)
   {
       if(num % i == 0)
           sum = sum + i;
   }

   return sum;
}

void main(int argc, char* argv[])
{
   int num1,num2, i, p, sumDivisors,j, number = 1;
   struct info *ptr;
   //clrscr();

   if(argc != 4)
   {
       printf("Insufficient arguments!\n");
       return;
   }
   else
   {
       // argv is a character array, convert to int to use the numbers
       // argv[0] contains program name
       num1 = atoi(argv[1]);
       num2 = atoi(argv[2]);

       if(num1 < 2)
       {
           printf("First number should be mroe than 2\n");
           return;
       }

       if(num1 > num2)
       {
           printf("Second number should be more than first number\n");
           return;
       }

       // dynamically allocate memory
       ptr = (struct info *)malloc(sizeof(struct info) * (num2-num1));

       p = 0;       // used in storing data into array of structures
       for(i = num1 ; i <= num2 ; i++)
       {
           sumDivisors = sumOfDivisors(i);
           (ptr + p)->lineNo = number;
           (ptr + p)->sum = sumDivisors;

           if(sumDivisors > i)
               (ptr+p)->msg = "Abundant";
           else if(sumDivisors < i)
               (ptr+p)->msg = "Deficient";
           else
               (ptr+p)->msg = "Perfect";

           number++;
           p++;
       }

           // printing now

       for(i = 0 ; i < p ; i++)
       {
           printf("%d is %s ", num1, (ptr+i)->msg);
           // printing |
           for(j = 0 ; j < (ptr+i)->sum ; j++)
               printf("|");

           printf("\n");
           num1++;
       }
   }
   //getch();
}

Output:

DOSBox 0.74, Cpu speed: max 100% cycles, Frameskip 0, Program: 15 is Def icient 16 is Def icient 17 is Def icient l 18 is Abundant HHHI 19 is Def icient l 20 is Abundanti TC
