    }
}

Have you tried running the code?

I'm pretty sure your compiler will tell you whether or not it makes sense.

so it doesn''''t make sense
computed error
any idea???
thanks

}

You have to be able to read what you've written, not just type things.

Hi thanks for your reply

Code:

---

#define MATRIX_SIZE      32

---

have include this in the heading. so I think it should create a mtrix with 32 X 32 ??

Code:

---

int n = 100 + rand() % 300;

---

This return 1 number between 100- 400 or create 100 - 400 numbers? ( I am looking to create 400 numbers)

In this case, do i still need to keep the second for- loop?


What i was think is generate 300 numbers between 1-1024 (My Matrix "32 X 32" )
and fill 1s into this wall.

How do i place 1 into array??
thanks thanks

Well, it means your declarations of matrix and matrix_data are 32x32 yes. Your for loop just has a random [32] in it, which is a syntax error.

One number between 100 and 400.

Since your second for loop is the only one that does anything at all, I would keep that one, yes.

And how could that possibly help you? So if you draw the number 875, what are you going to do with it? (Yes, I know that there is a way to do something with it, but I'm betting you don't.)

Not only have we told you this 23 times, you've already got it in your code

Code:

---

for (x = 0; x < 300; x++) matrix_data[rand()%MATRIX_SIZE][rand()%MATRIX_SIZE] = 1;

---

This line puts 300 1's in your matrix. It does. Really. (Granted, it may overlap by putting a 1 where there was one already, but ok.) You can stop asking now, please.

Okay, I'll backtrack a little bit -- I noticed that your arrays are characters, not integers; so change that to int matrix_data et cetera.

Thakns for you help. Spending time on my question XXTHXXX

So I need to change all char to int??

That's what I would recommend. And when printing out the matrix, if you're going to insist on putchar, make it putchar(matrix_data[row][col] + '0'); -- this will print 0s as '0' and 1s as '1'. (Right now, you're printing 0s as '' and 1s as 'smiley face'.

Still error.... sorry to be a pain....

You got a line number with that warning, although you didn't bother to mention what. Is code inside your structure a char variable?

Error E2171 antsimple2.cpp 646: Body has been defined for function 'main<>'

so i assue error on the followinf code

Code:

---

int main() {
int x;
srand(time(0));
for (x = 0; x < 300; x++) matrix_data[rand()&#37;MATRIX_SIZE][rand()%MATRIX_SIZE] = 1;
printf("%d\n", 1);
}

---

I have change char to int. this is the only error occur at the moment.


What else i need to modify???

thanks thanks

If you're getting that error now, you got that error before -- this means you have another int main() somewhere up above. You need to only have one main().

yes you r right.
I have tried change the name or place it inside the origianl int main()
however error still occuring

Error 713: Compound statement missing

what this mean??

cheerrrrs

Code:

---

void output_program(struct prog *progp)
{
  char *codep = progp->code;
  int token;

  while (token = *codep++)
    fputs(token_table[token].name, stdout);
  putchar('\n');
}

---

this function keep occur error.
I think I may missing the statement to put 1's?
or it is completely differetn thing?

You'll have to cut and paste the entire error message. You should also include what line it's on and some context for that line, if you want to have any hope of getting a meaningful answer.
