I am writing a recursive program to draw the lines recursively, given the
range and number of intervals (n) between the range.
The problem is I don't know how to draw the line in point 0.375, as you see below.
Please advise! Thanks!
#include <iostream>
using namespace std;

Hi all!
I have an int that comes with a value like 0x07fa and I have to turn it into
a float value of 204.2 decimal to display it.... if I try to divide it by
10 I get bogus numbers. I presume I have to make it decimal before
calculating, but I am not sure about it. Any light upon this simple (or it
seems to me so, at least) begginner...

Hi,
I am studying K&R book. On the multidimensional Arrays chapter they
say
"int (*daytab)
is a pointer to an array of 13 integers. The parenthesis are necessary
since brackets have higher precedence than *. Without parenthesis,
the declaration
int *daytab
is an array of 13 pointers to integers."

If I have:
unsigned char value = 0xBD;
unsigned char 2bits = 0x02;
How do I set the two MSB in value to the two LSB in 2bits without
changing any other bits in value?
<mytry>
value &= 0x3F; //set those two bits to zero

I have a declaration of a pointer to an array of a struct as follows:
struct foo (*a);
And I have an array of a struct as follows:
struct foo b;
However, a = &b returns an error (illegal assignment to constant).

Are the bitwise operators >>, <<, &, |, ~, ^ only defined for
non-negative values?
The little program below produces the output
3 255
I expected to get the 3 but why does it produce the 255 when the
variable c is not typecast first?

I have a .c file with a general code. It can be compiled with different
constants for different applications. For example
char a;
where BYTE_SIZE is a constant defined in an external (.h?) file.

If I do something like the following:
unsigned int bar=10;
Then use, -bar with the unary '-' and assign this value to an int,
does this invoke undefined behavior in anyway?
Basically I have:
unsigned int bar=10;
int foo;

What style do you prefer? Where to place brackets? How to name
variables, functions, constants, etc. How do you format your source
code? Do you write comments?

Problem: find a portable way to determine whether a compiler supports
the "long long" type of C99.
I thought I had this one solved with the following code:
#include <limits.h>
#ifdef ULONG_LONG_MAX

Hi,
I am trying to get as much information on void pointers. How do we take help
of void pointers in writing generic functions.
I have seen this kind of code for many years, but now I have got a chance to
write some myself.
Could anybody point me to a link where I can get more info for the same, or
refer me a book having more detail...

This is probably an easy question, but I have not used C for quite some
time: How do I determine the size of an array?
More specifically, how do I determine the number of incoming parameters?
Thanks.

Hello,
Unlike in pre-C99 versions of C where variables can only be defined at the
beginning of blocks, C99 allows variables to be defined in arbitrary
places inside blocks. However, gcc 3.2.2 seems to reveal that there
are still places where this is illegal. For instance, consider the
following code snippet.
int main(void) {
int i = 0;

When I'm reading from or writing to a network socket, I want to use a
struct to represent the structured data, but must use an unsigned char
buffer for the call to sendto() or recvfrom().
I have two questions:
1. Is it generally safe to "overlay" the structure on the buffer,
e.g.:
unsigned char buffer;
