Question

Code should be written in C

Use pointer variables for parameter passing, where appropriate and pointer arithmetic when working with arrays.

1) Using initialization lists, create 5 one-dimensional arrays, one for each of these:

• hold the names of the people running in the election
• hold the names of the subdivision
• hold the vote counts in the Brampton subdivision for each candidate
• hold the vote counts in the Pickering subdivision for each candidate
• hold the vote counts in the Markham subdivision for each candidate

Use the data from the example below.

* Your C program should take the data in the arrays and produce the output below, neatly formatted as shown:

Candidates                            Subdivisions                 Totals

                             Brampton  Pickering Markham        

Aubrey                     600            800          800            2200

Blake 700            700          600            2000

Chubbs 800           700          800           etc

Oliver 400            450         300             

Zamier 900            900       900            

Totals                     3400            etc                              etc

1. Create a function that will find the total votes in one subdivision and return that to main( ). Call this function 3 times to produce the 3 totals in the last line of output.
2. Create a function that will find the total votes for one candidate and return that to main( ). Call this function 5 times to produce the 5 totals in the last column of output. Be very careful with the parameter list here. Send the function only the information it needs.
3. Create a function that will output the first 2 lines of headings.

Answer 1

Executable code for the given problem is:

#include <stdio.h>
#include <stdlib.h>
void layout()
{
   //printing first two lines of output
   printf("candidates\t\tsubdivisions\t\ttotal");
   printf("\n\t\tbrampton pickering zamier");
  
}
int total_votes_sub(int *a)
{
   int i,t=0;
   for(i=0;i<5;i++)
   {
       /*finding sum of all the votes in a subdivision*/
       t=t+*(a+i);
   }
   return t;  
}
int total_votes_cd(int *a,int *b,int *c,int i)
{
   int t=0;
   /*finding all votes of single candidate from all subdivisions*/
   t=*(a+i)+*(b+i)+*(c+i);
   return t;
  
}
int main()
{
   /*declearing and initializing required variables*/
   int total_votes_brampton,total_votes_pickering,total_votes_zamier,i;
   int total_votes_count[100];
   /*storing names of candidates in names array*/
    char *names[5]={"aubrey","blakes","chubbs","oliver","zamier"};
    char *sub_names[100]={   "Brampton", "Pickering","Markham"};
   int brampton_count[5]={600,700,800,400,900};
   int pickering_count[5]={800,700,700,450,900};  
   int zamier_count[5]={800,600,800,300,900};  
   layout();
   /*finding total votes at each subdivision*/
   total_votes_brampton=total_votes_sub(brampton_count);
   total_votes_pickering=total_votes_sub(pickering_count);
   total_votes_zamier=total_votes_sub(zamier_count);
   for(i=0;i<5;i++)
   {
       /*finding all the votes of every candidate and storing in total_votes_count array*/
       total_votes_count[i] =total_votes_cd(brampton_count,pickering_count,zamier_count,i);
   }
   /*printing according to the requirement*/
   for(i=0;i<5;i++)
   {
       printf("\n%s\t\t%d \t %d\t    %d\t\t%d",names[i],brampton_count[i],pickering_count[i],zamier_count[i],total_votes_count[i]);
   }  
   printf("\ntotals\t\t%d\t %d \t   %d",total_votes_brampton,total_votes_pickering,total_votes_zamier);      
  
}

output of the given code is:
