Issue
First timer here; I'm trying to make a diary program in c following the cs50 reference
#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");
}
When I run the code with clang, it returns this error message
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

printf("You are %i, old\n");
~^

Is there something that I'm missing here? I installed the cs50 library in my OS and I even tried linking it and it returned the same error message. Thanks for any help! Cheers.
Update: The Code was updated with some help from a User below (Thank you David Cullen) and now the code looks like this.
#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);
}
However, when I run the program with clang I get a new error message.
/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)
I'm stumped
Solution
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);
^
This error means you cannot pass "What is your name?\n"
to GetString
.
Diarytest.c:11:22: warning: more '%' conversions than data arguments
[-Wformat]
printf("Hello there %s, name\n");
~^
This error means you have to supply another parameter to printf
here (maybe 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);
^
Similar to the above problem, you cannot pass "What is your age?\n"
to GetInt
.
Diarytest.c:15:18: warning: more '%' conversions than data arguments
[-Wformat]
printf("You are %i, old\n");
~^
2 warnings and 2 errors generated.
Once again, you have to supply another parameter to printf
here (maybe age
).
