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。
- 谢谢-谢谢

将cs50库链接添加到编译命令中。如何操作将在第2周的笔记和视频中解释。第一个主题是关于编译的。
此外,当您在尝试编译时输入命令时,而不仅仅是输出时,将其置于引号中会提供更多信息
