Name Problem: First, Middle, Last

**Sedition X** · 01-31-2011

Hey everybody, now i am working on this program that will ask you your name and then says Welcome (name), but i also want it to be able to say your full name like Welcome (first, middle, last), but every time i put 1 or 2 words in like (first, last) in it does nothing.

See for you self, its hard to explain

Code:

#include<stdio.h>

int main(Void)
{
    char First[25];
    char Middle[25];
    char Last[25];
    
    printf("Please Enter Your Name: ");
    scanf("%s%s%s", First, Middle, Last);
    
    if(Middle == || Last == )
    {
    printf("Welcome %s", First);           
                   }
    
    getch();
    }

That doesn't even compile.

Sorry

Code:

#include<stdio.h>

int main(Void)
{
    char First[25];
    char Middle[25];
    char Last[25];
    
    printf("Please Enter Your Name: ");
    scanf("%s%s%s", First, Middle, Last);
    
    if(Middle == 0)
    {
    printf("Welcome %s", First);           
                   }
    
    getch();
    }

don't use stuff like getch()
it doesn't make your code portable..you need to use conio.h...
better to use getchar() at least

%s returns when it sees a space or newline..so i think a trick is to do
"%s %s %s"..but I suggest you use fgets or separate the scanfs instead of a quick shortcut

I have done this to it but it still won't work

Code:

#include<stdio.h>
#include<conio.h>

int main(Void)
{
    char First[25];
    char Middle[25];
    char Last[25];
    
    printf("Please Enter Your Name: ");
    scanf("%s", First);
    scanf("%s", Middle);
    scanf("%s", Last);
    
    if(Middle == 0)
    {
    printf("Welcome %s %s", First, Last);           
                   }
    
    else if(Middle, Last == 0)
    {
    printf("Welcome %s", First);           
                   }
    
    getch();
    }

                   }
    
    getch();
    }

else if(Middle, Last==0)

incorrect... else if (Middle ==0 && Last==0)

...
why're you comparing with 0?

**Sedition X** · 01-31-2011

I am comparing with 0 because i don't know what else to compare it with, any ideas?

i asked because I have no idea why you want the if statement for..
on what condition do you want to display the first name, or first and last name?

**Sedition X** · 01-31-2011

I want it to be able to display the first, last and middle name if necessary

**Eman** · 01-31-2011

what do you mean by "if necessary"

i mean the user would have to enter an input i guess...
but what you're doing..the logic is wrong.
you're checking if you're attempting to check if your string is empty..and knowing that yet you still try to print something (if Middle is empty, we're assuming that Last and First aren't as well).

can you be more clear on why you want to display the strings if necessary

**Sedition X** · 01-31-2011

I want to be able to type in the first name, the middle name and the last name but not all at the same time.

**Eman** · 01-31-2011

i thought you wanted to display them?
btw does it compile for you..

**Sedition X** · 01-31-2011

I want them to come up on screen, and yes it does compile for me

**Eman** · 01-31-2011

odd..i would have thought "Void" would cause an error

printf("%s %s %s", First, Last, Middle) ;

no need for if statements

Do you have a code??
