Drawing Table With C Language

Question

Hi!, I have a problem with the table closing. I want to close the table with some dynamic strings on it, so how to fix the table closing position?, Thankyou

#include <stdio.h>

char top[500] = "\xda\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc2\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xbf\n";

char border[500] = "\xc3\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc5\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xb4\n";

char bottom[500] = "\xc0\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc1\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xc4\xd9\n";

char nama[30];
char alamat[150];
char telepon[15];
char email[50];

int main(){
    printf("Masukan Nama Lengkap : ");gets(nama);
    printf("Masukan Alamat Anda : "); gets(alamat);
    printf("Masukan Nomor Telepon Anda : "); gets(telepon);
    printf("Masukan Email Anda : "); gets(email);

    printf(top);
    printf("\xb3 Nama     \xb3 %s                                          \xb3\n", nama);
    printf(border);
    printf("\xb3 Alamat   \xb3 %s                                          \xb3\n", alamat);
    printf(border);
    printf("\xb3 No.Telp  \xb3 %s                                          \xb3\n", telepon);
    printf(border);
    printf("\xb3 Email    \xb3 %s                                          \xb3\n", email);
    printf(bottom);
    printf("\xfb");
    return 0;
}

Use printf with left alignment and fixed width. Something like: `printf("\xb3 %-10s \xb3 %-30s", "Nama", nama);` Those numbers are just examples - you will need to change them for your desired column widths. — kaylum, Sep 11 '21 at 06:12

When printing a table you need to control how many characters you print in the individual cells. The conversion specifier for printf(fprintf) allows you to do that. The standard says (draft N1570):

Each conversion specification is introduced by the character %. After the %, the following appear in sequence:

...

— An optional minimum field width. If the converted value has fewer characters than the field width, it is padded with spaces (by default) on the left (or right, if the left adjustment flag, described later, has been given) to the field width.

and

The flag characters and their meanings are:

- The result of the conversion is left-justified within the field. (It is right-justified if this flag is not specified.)

So if you use %100s for printf and you provide a string being less than 100 characters, printf will add spaces so that the number of characters printed is exactly 100.

Using %100s or %-100s you can control justification of the string.

int main(void) 
{
    char* str = "Hello World";
    printf("| %30s |\n", str);
    printf("| %-30s |\n", str);
    return 0;
}

Output:

|                    Hello World |
| Hello World                    |

Notice: If your string is longer than the field width specified, printf will still print all of your string. So you need to make sure that the strings can always be contained inside the cells of the table.

BTW:

You should read Why is the gets function so dangerous that it should not be used?
