如何用C语言写日记？

Question

这里是第一个计时器；我正在尝试按照cs50参考在c中制作一个日记程序

#include <cs50.h>
#include <stdio.h>
#include <unistd.h>

int main(void)

{

//Program ask user for their name
string name = GetString("What is your name?\n");
printf("Hello there %s, name\n");

//Program ask user for their age
int age = GetInt("What is your age?\n");
printf("You are %i, old\n");

}

当我使用 clang 运行代码时，它会返回此错误消息

Diarytest.c:10:25: error: too many arguments to function call, expected 0,
      have 1
string name = GetString("What is your name?\n");
              ~~~~~~~~~ ^~~~~~~~~~~~~~~~~~~~~~
/usr/local/include/cs50.h:106:1: note: 'GetString' declared here
string GetString(void);
^
Diarytest.c:11:22: warning: more '%' conversions than data arguments
      [-Wformat]
printf("Hello there %s, name\n");
                    ~^
Diarytest.c:14:18: error: too many arguments to function call, expected 0,
      have 1
int age = GetInt("What is your age?\n");
          ~~~~~~ ^~~~~~~~~~~~~~~~~~~~~
/usr/local/include/cs50.h:87:1: note: 'GetInt' declared here
int GetInt(void);
^
Diarytest.c:15:18: warning: more '%' conversions than data arguments
      [-Wformat]
printf("You are %i, old\n");
                ~^
2 warnings and 2 errors generated.

这里有什么我遗漏的吗？我在我的操作系统中安装了 cs50 库，我什至尝试链接它，它返回了相同的错误消息。谢谢你的帮助！干杯。

更新：代码在下方用户的帮助下进行了更新（感谢 David Cullen），现在代码如下所示。

#include <cs50.h>
#include <stdio.h>
#include <unistd.h>

int main(void)

{

//Program ask user for their name
string name = GetString();
printf("Hello there, %s\n", name);

//Program ask user for their age
int age = GetInt();
printf("You are, %i\n", age);

}

但是，当我使用 clang 运行程序时，我收到一条新的错误消息。

/usr/bin/ld: /tmp/Diarytest-862733.o: in function `main':
Diarytest.c:(.text+0x9): undefined reference to `GetString'
/usr/bin/ld: Diarytest.c:(.text+0x2a): undefined reference to `GetInt'
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我被难住了

Answer 1

Diarytest.c:10:25: error: too many arguments to function call, expected 0,
      have 1
string name = GetString("What is your name?\n");
              ~~~~~~~~~ ^~~~~~~~~~~~~~~~~~~~~~
/usr/local/include/cs50.h:106:1: note: 'GetString' declared here
string GetString(void);
^

此错误表示您无法将"What is your name?\n" 传递给GetString。

Diarytest.c:11:22: warning: more '%' conversions than data arguments
      [-Wformat]
printf("Hello there %s, name\n");
                    ~^

此错误意味着您必须在此处向printf 提供另一个参数（可能是name）。

Diarytest.c:14:18: error: too many arguments to function call, expected 0,
      have 1
int age = GetInt("What is your age?\n");
          ~~~~~~ ^~~~~~~~~~~~~~~~~~~~~
/usr/local/include/cs50.h:87:1: note: 'GetInt' declared here
int GetInt(void);
^

与上述问题类似，不能将"What is your age?\n" 传递给GetInt。

Diarytest.c:15:18: warning: more '%' conversions than data arguments
      [-Wformat]
printf("You are %i, old\n");
                ~^
2 warnings and 2 errors generated.

再一次，您必须在此处向printf 提供另一个参数（可能是age）。
