erros

i keep getting an error in this prog..

#include <stdio.h>

#define xlordt '*'

struct char xlordt[7]={
{x,l,o,r,d,t},
};

int main()
{

int x;

for (x=0; x<1; x++)
putc( xlordt[x], stdout);

return 0;
}


the error that i keep getting is..
dd.c:5: parse error before `char'
dd.c: In function `main':
dd.c:15: subscripted value is neither array nor pointer

can anyone tell me what this means... (running under linux)

Comments:

1. struct char is not valid
2. you use xlordt two times
3. the array initialisation is wrong

Explanation:

>dd.c:5: parse error before `char'

That's because of point 1.

>dd.c: In function `main':
>dd.c:15: subscripted value is neither array nor pointer

That's because of point 2.

umm sorry but. i really dont get what you are saing(newbie) =(

You defined xlordt as '*'. This would mean that

struct char xlordt[7]={

would become

struct char '*'[7]={

which is not valid.

The construction "struct char" is invalid. The keyword "struct" means that you're defining a structure, like in:

struct mystruct
{
/* some data */
};

This is quite a crap way of doing it, but hey it works.

Code:

---

#include <stdio.h>

typedef struct xlordt{
  char xlord[7];
}xlord_t;

int main(){
  int i;
  xlord_t test;
  test.xlord[0] = 'x';
  test.xlord[1] = 'l';
  test.xlord[2] = 'o';
  test.xlord[3] = 'r';
  test.xlord[4] = 'd';
  test.xlord[5] = 't';
  for(i = 0; i<sizeof(test.xlord); i++)
    printf("%c",test.xlord[i]);
  return 0;
}

Quote:

---

struct char xlordt[7]={
{x,l,o,r,d,t},
};

when your defining a structure your defining a type you cant initialise a type

Code:

---

typedef struct{
    char name[7];
}XLORDT;

---

now you declare a variable of type XLORDT

Code:

---

XLORDT xlordt;

---

when you refer to a field of your structure you need to use the dot operator

Code:

---

putc( xlordt.name[x], stdout);

---

However if you only have 1 field in your structure it's all a waste of time, you may as well just have an array.

Code:

---

#include <stdio.h>
#include <string.h>

typedef struct{
        char name[7];
}XLORDT;

int main( void )
{

        int x;
        XLORDT xlordt;

        strcpy( xlordt.name, "xlordt" );

        for (x=0; x<7; x++)
        putc( xlordt.name[x], stdout);

        return 0;
}

mind if i ask what does.. typedef means i know i read it somewere but i didnt understand it to much. btw thanx

To xlordt,

Note that typedef is used to define a type, like in:

typedef unsigned int UINT;

Here there is a type MyUINT created. This type is the same as unsigned int. It is usually used to prevent from typing very much. Instead of

unsigned int var;

one can now use

UINT var;

Code:

---

#include <stdio.h>

char xlordt [7] = {'x','l','o','r','d','t','\0'};

int main (void)
{
        int x;
       
        printf ("%s\n", xlordt);
       
        for (x = 0; x < 7; x++)
            printf ("%c", xlordt [x]);   

        return 0;
}

btw, xlordt you have posted loads of times, it's about time you started using code tags

thanx.. sorry sometime i dont understand something... thanx

There's no need for excuse. Everybody sometimes doesn't understand something and needs some help, that's why these boards are here.

its imbarassing that i have been trying to code for quite some time now and i have not learn well enough. There are lots of thing that i really dont understand. Other things i learnd well but c programming is a great big challenge for, but anyways i guess i will keep on tring. btw thanx again for your help..

keep trying and you will succeed.
The important thing is that you took up the challenge, unlike so many who talk about it but never do it.
:)

heh ya easyer said then done.. the code that i posted here im tring to change it to pring in to ascii and i dont want to post it till i try, but i have the leest bit on how to do it heheh.. but thanx for your help on keeping my head up.. :D
