我正在尝试解决cs50课程中的一个问题集，然而，当我尝试在我的桌面版本的Visual Studio Code上运行以下代码时，我遇到了编译错误。

#include <stdio.h>
#include <string.h>
#include "cs50.h"

// Max number of candidates
#define MAX 9

// Candidates have name and vote count
typedef struct
{
    string name;
    int votes;
}
candidate;

// Array of candidates
candidate candidates[MAX];

// Number of candidates
int candidate_count;

// Function prototypes
bool vote(string name);
void print_winner(void);

int main(int argc, string argv[])
{
    // Check for invalid usage
    if (argc < 2)
    {
        printf("Usage: plurality [candidate ...]\n");
        return 1;
    }

    // Populate array of candidates
    candidate_count = argc - 1;
    if (candidate_count > MAX)
    {
        printf("Maximum number of candidates is %i\n", MAX);
        return 2;
    }
    for (int i = 0; i < candidate_count; i++)
    {
        candidates[i].name = argv[i + 1];
        candidates[i].votes = 0;
    }

    int voter_count = get_int("Number of voters: ");
    // Loop over all voters
    for (int i = 0; i < voter_count; i++)
    {
        string name = get_string("Vote: ");

        // Check for invalid vote
        if (!vote(name))
        {
            printf("Invalid vote.\n");
        }
    }
    // Display winner of election
    print_winner();
}

// Update vote totals given a new vote
bool vote(string name)
{
    // TODO
    for (int i=0;i<candidate_count;i++){
        if(!strcmp(name,candidates[i].name)){
            candidates[i].votes +=1;
            return true;
        }
    }

    return false;
}
// Print the winner (or winners) of the election
void print_winner(void)
{
    // TODO
    int max=0;
    string max_name = "";
    for (int i=0;i<candidate_count;i++){
        if(max<candidates[i].votes){
            max = candidates[i].votes;
            strcpy(max_name,candidates[i].name);
        }
    }
    for (int i=0; i<candidate_count;i++){
        if(candidates[i].votes==max){
            printf("%s\n",candidates[i].name);
        }
    }
    return;
}

终端出现以下错误;

我已经使用以下链接设置了我的Visual Studio Code for C/C++; https://code.visualstudio.com/docs/languages/cpp
终端显示程序无法同时编译外部头文件，您能否指导我完成此操作，因为这是我第一次使用C/C的VS代码，之前我曾在Dev C上工作，如果有一些特定的配置：如果您想建议在C/C++程序中使用VS代码，我们将不胜感激。
