cs50 - problem set 3 plurality- code failed to compile

Question

The code I made is for cs50 problem set 3 plurality. When I run the code myself, the code works as expected. However when I run check50, I get the error "code failed to compile". When I run check50 i get this error:

:) plurality.c exists
:( plurality compiles
    code failed to compile
:| vote returns true when given name of first candidate
    can't check until a frown turns upside down
:| vote returns true when given name of middle candidate
    can't check until a frown turns upside down

This is my code:

#include <stdio.h>
#include <string.h>
#include <math.h>
#include <ctype.h>
#include <cs50.h>
#include <stdbool.h>
#include <string.h>

int main(int argc, string argv[])
{
     
    if(argc<2)
    {
        return 1;
    }
    
    int cand_count = argc-1;
    
    if ((cand_count)>9)
    {
        return 1;
    }
    
    int scores[]={0,0,0,0,0,0,0,0,0};
    
    int voters_count=get_int("Number of voters: ");
    
    for (int a=0; a<voters_count; a++)
    {
        string question =get_string("vote: ");
        
        for (int b=0; b<cand_count; b++)
        {
            
            if (strcmp( question, argv[b+1]) == 0 )
            {
                scores[b]=(scores[b]+1);
            }
        }
        
    }
    
    int highest=0;
    int position=0;
    
    for (int d=0; d<9; d++)
    {
        if ((scores[d])>(highest))
        {
            highest=scores[d];
            position=d;
        }
    }
    printf("%s",argv[position+1]);
    
}

Can you please help me fix this error.

Answer 1

From the spec

You should not modify anything else in plurality.c other than the implementations of the vote and print_winner functions (and the inclusion of additional header files, if you'd like).

Best to start with the distro code .
