Fscanf scanning incorrect information

Question

I'm a student tryig to print 6 lines I have inserted into a txt document called test.txt

The test file is simple plain text in a .txt with the following text, all on its own line:

Nikolaj
Ljorring
m
20
182
200

However, I need to put the loaded data into a struct which look likes this:

struct profile_info
{
char first_name[30];
char last_name[30];
char gender;
int age;
int height;
double weight;
};

And a loader / printing function that looks like so:

void user_profile_loader(struct profile_info user_profile)
{
FILE *file_pointer;
file_pointer = fopen("test.txt", "r");

fscanf(file_pointer, "%s", &user_profile.first_name);

fscanf(file_pointer, "%s", user_profile.last_name);

fscanf(file_pointer, "%c", &(user_profile.gender));

fscanf(file_pointer, "%d", &(user_profile.age));

fscanf(file_pointer, "%d", &(user_profile.height));

fscanf(file_pointer, "%d", &(user_profile.weight));

printf("%s \n%s \n€c \n%d \n%d \n%lf", &user_profile.first_name, &user_profile.last_name,
user_profile.gender, user_profile.age, user_profile.height, user_profile.weight);

fclose(file_pointer);
}

However, my output looks like so:

Nikolaj
Ljorring
(wierd C with a line beneath it)c [So a wierd C followed by a normal lowercase c]
10
5
0.000000

Answer 1

fscanf(file_pointer, "%s", &user_profile.first_name);
                           ^ no need of & here 

And here -

fscanf(file_pointer, "%d", &(user_profile.weight));

You use %d to read a double value .You pass wrong argument it invokes UB .Use %lf here.

In your printf -

printf("%s \n%s \n€c \n%d \n%d \n%lf", &user_profile.first_name, 
 &user_profile.last_name,user_profile.gender, user_profile.age, user_profile.height, user_profile.weight);

What is \\n€c ? You should use specifier %c .

Note - You should check return of fopen and fscanf .
