BALLOTS

  • Problem Description

    An election is contested by 5 candidates. The candidates are numbered 1 to 5 and the voting is done by marking the candidate number on the ballot paper. Write a program to read the ballots and count the votes cast for each candidate using an array variable count. In case a number read is outside the range 1 to 5 ballot should be considered as a spoilt ballot and the program should also count the number of spoilt ballots
  • CODING ARENA::
  • #include<stdio.h>
    int main()
    {
        int count[6],mark,bn,i;
        for(i=0;i<=5;i++)
        {
            count[i]=0;
        }
        
        scanf("%d",&bn);
        for(i=0;i<=bn-1;i++)
        {
            
            scanf("%d",&mark);
            if(mark==1)
            {
                ++count[0];
            }
            else if(mark==2)
            {
                ++count[1];
            }
            else if(mark==3)
            {
                ++count[2];
            }
            else if(mark==4)
            {
                ++count[3];
            }
            else if(mark==5)
            {
                ++count[4];
            }
            else
            {
                ++count[5];
            }

        }
        printf("Candidate 1=%d\n",count[0]);
        printf("Candidate 2=%d\n",count[1]);
        printf("Candidate 3=%d\n",count[2]);
        printf("Candidate 4=%d\n",count[3]);
        printf("Candidate 5=%d\n",count[4]);
        printf("Spoil Ballot=%d",count[5]);
        return 0;
    }


  • Test Case 1

    Input (stdin)
    6
    
    6 7 8 9 8 8
    
    
    Expected Output
    Candidate 1=0
    
    Candidate 2=0
    
    Candidate 3=0
    
    Candidate 4=0
    
    Candidate 5=0
    
    Spoil Ballot=6
  • Test Case 2

    Input (stdin)
    23
    
    1 1 1 1 1 2 2 2 2 2 3 3 3 3 4 4 4 5 5 7 9 7 8
    
    
    Expected Output
    Candidate 1=5
    
    Candidate 2=5
    
    Candidate 3=4
    
    Candidate 4=3
    
    Candidate 5=2
    
    Spoil Ballot=4
