why does my program print off the wrong answers?

ok my program is relitivly simple at the moment but i cant get it to print out what class and id that you select will some one show me what i did wrong??

Code:

---

#include <stdio.h>
 main ()
{
char *class_name[03]={"hunter","ranger","force"};
char *statnum  [06]={"SYNC","IQ  ","DEF ","POW ","DEX ","MIND"};
char *section_id[10]={"viridia","greenil","skyly","bluefull"  ,"purplenum",
                  "pinkal" ,"redria" ,"oran" ,"yellowboze","whitill"};
int *ID;

int *class;
int blah;
int qwe;
int comm[4][9];
        int stat[7][2];                        /* initialize STATS */
    for (qwe=0;qwe<7;qwe++)
    {
      for (blah=0;blah<2;blah++)
      {
            stat [qwe][blah] =0;
      }
    }       
    stat [0][0] =40;                        /* initialize SYNC */
    stat [2][0] =5;                        /* initialize DEF */
    printf ("Enter section ID \n");
    for (qwe=0;qwe<10;qwe++)
    {
    printf ("%i : %s\n",qwe,section_id[qwe]);
    }
    scanf  ("%i",&ID);
blah=ID;

 
    printf ("Enter character class \n");
    for (qwe=1;qwe<4;qwe++)
    {
    printf ("%i :  %s\n",qwe,class_name[qwe-1]);
    }
    scanf  ("%i",&class);
   
  printf ("your section id is\n %s \n",section_id[*ID]);
  printf ("your class is \n%s \n",class_name[*class-1]);
 
 
for (qwe=0;qwe<6;qwe++) printf ("%s is %i . %i \n",statnum[qwe],stat[qwe][0],stat[qwe][1]);

}

First thing I noticed:

Quote:

---

char *class_name[03]={"hunter","ranger","force"};
char *statnum [06]={"SYNC","IQ ","DEF ","POW ","DEX ","MIND"};

---

Get rid of the preceeding 0. The preceding 0 changes it from a base 10 number to a base 8 (octo) number. While it doesn't have much affect as of yet it could potentionally become a problem later if you don't learn it now ;)

Also:

Code:

---

blah=ID;

---

blah is an int and ID is a pointer to an int.

Change ID and class to be ints, instead of pointers to ints.

Remove this:
>blah = ID;

At least you should be on your way...

ok i changed what you guys said to but it still gives me part of one of the strigs, (null) or just blank heres the revised code tell me is theres any part i missed

Code:

---

#include <stdio.h>
 main ()
{
char *class_name [3]={"hunter","ranger","force"};
char *statnum    [6]={"SYNC","IQ  ","DEF ","POW ","DEX ","MIND"};
char *section_id[10]={"viridia","greenil","skyly","bluefull"  ,"purplenum",
                  "pinkal" ,"redria" ,"oran" ,"yellowboze","whitill"};
int ID;
int class;
int blah;
int qwe;
int comm[4][9];
        int stat[7][2];                        /* initialize STATS */
    for (qwe=0;qwe<7;qwe++)
    {
      for (blah=0;blah<2;blah++)
      {
            stat [qwe][blah] =0;
      }
    }       
    stat [0][0] =40;                        /* initialize SYNC */
    stat [2][0] =5;                        /* initialize DEF */
    printf ("Enter section ID \n");
    for (qwe=0;qwe<10;qwe++)
    {
    printf ("%i : %s\n",qwe,section_id[qwe]);
    }
    scanf  ("%i",ID);

    printf ("Enter character class \n");
    for (qwe=1;qwe<4;qwe++)
    {
    printf ("%i :  %s\n",qwe,class_name[qwe-1]);
    }
    scanf  ("%i",class);
   
  printf ("your section id is\n %s \n",*section_id[ID]);
  printf ("your class is \n%s \n",*class_name[class-1]);
 
 
for (qwe=0;qwe<6;qwe++) printf ("%s is %i . %i \n",statnum[qwe],stat[qwe][0],stat[qwe][1]);

}

thanx

ok i changed

Code:

---

  printf ("your section id is\n %s \n",*section_id[ID]);
  printf ("your class is \n%s \n",*class_name[class-1]);

---

to

Code:

---

  printf ("your section id is\n %i \n",ID);
  printf ("your class is \n%i \n",class-1);

---

and when you in put you get

your section id is (random number less or = to 0)
your class is -29

so now yeah..........im lost

Sorry, I should have said before:
>scanf ("%i",&ID);
>scanf ("%i",&class);
Note: You need the & when you're using a real int variable.

ok sweet that worked now i have one more question
how can i check to make shure that what you input has no decimals would it be a stament like

Code:

---

if (ID!=round(ID)) return (0);

---

and if thats what i need do i need any new include staments?

round is in math.h and you would need to include that. and if in gcc you would need to compile with

Code:

---

gcc -o test test.c -lm

---

[edit] Now looking at your code you cannot have ID as a decimal, because your number is an int.[/edit]
[edit]and I would change scanf("%i... to scanf("%d... because %i can intake other number bases say I enter 023 that is octal. I don't think you would want that.[/edit]
[edit](Wow I need to stop) if you wanted to use the round function you would have to coerce or typecast ID to a double or use roundf then you would have to force it a float. You also don't use the variable comm and you shoud have int main(void) not main(){ then you need to return 0[/edit]

wow look like you had fun editing
and the reason for there being pointless ints and no return at the end is because this is just the 1st part of my program

i found another question is there a command to clear you screen insted of it just scroling like it does?

they are all OS dependent if you are in linux it is

Code:

---

system("clear");

---

in DOS

Code:

---

system("cls");(I think)

---

or if you have conio.h

Code:

---

#include <conio.h>
...
clrscr();

---

You could have just told them to read the FAQ link on it, or search the forum, since this question gets posted about fifty times a week.

Quzah.

I felt ambitious :D

>>how can i check to make shure that what you input has no decimals
http://faq.cprogramming.com/cgi-bin/...&id=1043284385

yeah the reason i asked about how to clear screen is because ever time i try

Code:

---

system("cls");

---

it goes to the start of main()

but now i have a final question for this thread i need to make a 3D int thats size is 8X11X6 the data is inbetween -99 and 99 heres like what i would need

the matix [1][][] is

3,3,5,40,5,0,
3,3,10,45,5,0,
4,4,15,50,10,0,
3,3,5,0,5,40,
3,3,10,0,5,45,
4,4,15,0,10,50,
3,3,5,10,40,0,
3,3,5,0,44,10,
4,1,15,30,15,25,
4,1,15,25,15,30,
6,5,25,25,25,25

but im not shure on how to put in in to the program

thanx
