Thread: Space between lines (common)

Code:

    char date[20]; 
    printf("Date: "); 
    scanf("%[^\t\n]s", &date);

coding error,

Code:

gcc -Wall -o "Space_between_lines" "Space_between_lines.c" (in directory: /home/userx/bin)
Space_between_lines.c: In function 'main':
Space_between_lines.c:16:11: warning: format '%[^
' expects argument of type 'char *', but argument 2 has type 'char (*)[20]' [-Wformat=]
     scanf("%[^\t\n]s", &date);
           ^
Compilation finished successfully.

what is that format trying to get?

EDIT

Code:

   char date[20]; 
    printf("Date: "); 
    scanf("%s", date);

Code:

userx@slackwhere:~/bin
$ ./Space_between_lines
Who is this invitation from: me
Who is this invitation to: you
Date: 12/23/44

Time: 23:34

Duration (h): Where: // not working 

Hello you

You are invited to a party the 12/23/44 at 23 in :34.
The party lasts until -233

See you there!meuserx@slackwhere:~/bin

now you need to fix the duration as it skips it. You might want to add
the format you want that date entered in your printf

and put an endline on your last printf
printf("%s\n", host);

this just would require a little fancy coding, for me anyways.
the need to know how it is being added to is needed.

month/day/year
day month year
etc..

Code:

And I need this whole string to be printed out in the message 
"You are invited to a party the %s at ..."
"You are invited to a party the 12th of April at ..

so you can get your input then parse it. then print it out how you want.

this is just missing something

Code:

printf("\nDuration (h): ");
scanf("%hd", &duration);

a simple oops mistake.

SOLUTION

Apparently white space in front of the %-sign seems to make a difference?

Code:

#include <stdio.h>


int main() {
    
    char host[20];
    printf("Who is this invitation from: "); 
    scanf("%s", host);
    
    char name[20];
    printf("Who is this invitation to: "); 
    scanf("%s", name);
    
    char date[20]; 
    printf("Date: ");
    scanf(" %[^\n]s", date); // white space in front of the %-sign seems to make a difference?
    
    short time, duration; 
    printf("Time: "); 
    scanf("%hd", &time); 
    
    printf("Duration (h): "); 
    scanf("%hd", &duration); 
    
    char destination[20]; 
    printf("Where: "); 
    scanf("%s", destination); 
    
    printf("\n\nHello %s", name); 
    printf("\n\nYou are invited to a party the %s at %hd in %s.", date, time, destination);
    
    short lastsUntil = time + duration;
    printf("\nThe party lasts until %hd", lastsUntil);
     
    printf("\n\nSee you there!\n"); 
    printf("%s", host); 
    return 0;
}
