I am currently debugging this function. I am trying to make this function's width specifier align like a printf() routine. Here 's the code:
v Code:
oid
bu_log(const char *fmt, ...) {
va_list ap;
struct bu_vls output = BU_VLS_INIT_ZERO;
if (UNLIKELY(!fmt || strlen(fmt) == 0)) {
bu_vls_free(&output);
[Code] ....
Is there a way to auto align a cpp file?

In the following example, how 'd I use sprintf when I have a boolean type of variable?
Code:
char s[64];
bool bVar = false;
sprintf(s, "This is a boolean variable bVar = %?", bVar);
What is supposed to replace ? in the sprintf statement ?

I need to create certain objects which are listed in a file. So my code needs to run a loop and create objects(of type specified in file) and put them in a list.
It appears to me that type specifiers can't be replaced by string. Is there a way out ? I want following code to be working somehow.
#include <iostream>
#include <string>
using namespace std;

i want to write a program that input a text from user and align it to the left. Is there any command that i can use? How should i think?

When I compile my code I get an error saying that I need declaration specifiers in my is_prime subroutine in the for loop.
Here is the line of code it references.
for(j = 2; j < k; j++)
I realize that implicit int rule was removed in C99 but gcc still takes this approach by default. I wonder why this happens:
bbb = 5; // legal
int main(void) {
aaa = 10; // illegal
auto aaa = 10 // legal
Inside function a specifier is needed. Error message with no specifier used is:
error: ‘aaa’ undeclared (first use in this function)
Is this because of linkage - bbb variable has an external linkage so compiler knows that we are defining a variable here while inside mean() we need to show compiler that aaa is defined right here, it does not come from external functions?
I want to learn ow to align an integer/decimal values on the Left inside devexpress gridview.

It said my width1 is being used wihtout being initialized.. what does it mean?
#include<iostream>
using namespace std;
double Area(double height, double width);
double Perimeter(double height, double width, double height1, double width1);
[Code] .....
Basically when I type in different widths and heights for the col and rows, the buttons that make up the width get cut off. Something is messed up but I'm not sure what!
InitializeComponent();
int _col = int.Parse(cols);
int _row = int.Parse(rows);
int width = groupBox1.Width;
int height = groupBox1.Height;
int bW = width / _col;
int bH = height / _row;
[Code] ....
The program is when a person clicks a button this button updates 2 separate listbox one tracks the total rolls the other displays the total amounts of frequency afterwards adjusting labels as a scaling measurement.
The problem I am having is right at the end where I am trying to adjust the width of the label this is what I have. It is highlighting the word "Items" for each label and says that Non-Invokable member 'System.Windows.Forms.ListBox.Items' Cannot be used like a method L2 is a label. Additionally I have added in the information for one of my loops below the line I am having trouble with this loop is created to determine how many lines are in the listbox of rolls and I have no trouble with this just thought id add it for additional information I dont think I need to add the rest of the code but I can if needed.
L2.Width = int.Parse(lstfrequency.Items(0).ToString());
TL = 0;
for (I = 0; I <= 10; I++)
{
TL += int.Parse(lstfrequency.Items[I].ToString());
}
lstfrequency.Items.Add(TL);
The problem says:
Define functions n(), s(), e(), w(), center(), ne(), se(), sw() and nw(). Each takes a Rectangle argument and returns a Point. These functions define connection points on and in the rectangle. For example, nw® is the northwest (top-left corner) of a rectangle called r.
I wrote below code for that:
#include <Simple_window.h>
Point n(const Graph_lib::Rectangle& r);
Point s(const Graph_lib::Rectangle& r);
Point e(const Graph_lib::Rectangle& r);
Point w(const Graph_lib::Rectangle& r);
Point ne(const Graph_lib::Rectangle& r);
Point se(const Graph_lib::Rectangle& r);
[Code]...
As you see, this just mark the top-left corner of the rectangle r. In other functions I need the specifications of that rectangle, for example its height and width. How to use these specs in those functions?
I am drawing two circle (inner circle and outer circle) using DrawElipse method. I have created two pen object named OuterPen and InnerPen and creating Outer Circle using OuterPen and Inner Circle using InnerPen. Problem that I am facing is that when I increase the size of outer pen lets say 10px then it overlaps the inner circle and inner circle is hide. How can I increase the size of OuterPen outwards and not inwards so that it don't overlap the inner circle?

When it prints the values, it prints them as I want. the problem is, what happens when someone puts in values with different width and precision? Here I had to write in the width and precision to display the values that are specified in the book. but what happens when someone puts in something that doesn't have those width/precision?
I end up with a lot of zeros after the number. initially I got 24.000000 (zeros are not accurate amount) I needed to show just 24. (with the decimal)
So I included %2.0f which gave me 24 (without the decimal point) what if some one put in 24.556. I got 25 as a result.
Does the width mean how many numbers in total including the decimal point and that is a minimum?

how do i change this code to accept two numbers from the user and print it as the different length and widtth? it has to be a for loop as well.[code]
I have to output a series of data, I have to control the width of parts of my data. like following:
double a[] = {1.0, 2.0, 3.0};
double b[] = {1.5, 2.5, 3.5};
ofsteam myfile("result.txt");
for(int i=0; i<3; i++) {
myfile.width(5);
myfile << i+1 << " : " << a[i] << " - " << b[i] << end;
}
I only want to fix the width of a[i], b[i], but let the rest to be output normally.
how I can make it?

I derived a class from CRecentFileList in order to set the number of displayed chars for MRU.
The problem is that if I open the app with 256 set for this number (it is read from .ini file) the display is correct. But after I change it to 10 for e.g., File menu width remains unchanged altghough MRU are correctly displayed on 10 (or at least file name lenghts) chars.
how can I tell to the menu to shrink to actual width?
How to read and write an arbitrary number of bits from/to a file stream.
For instance, how to repeatedly read 9 bits from a file, then change to 10 bits, then 11 bits, and so on?
Obviously one way is by doing a lot of bit shifting, and masking. But honestly, I'm too dumb to get it right. Then I thought about using std::bitset and std::vector<bool>.
I m trying to load a png image by giving the dimension of my own.
CImage Image;
Image.Load (L"D:ImagesPNG_ImagesImage7.png");
But here what happens is that I m not able to give my own dimensions.My code requires constant changing of dimensions of the image.
I tried using libpng.lib in my code.But I dono the keywords for loading the png image after including the lib.
I m using Visual Studio 2010. I m developing in vc++.
How do I load and change the height and width of a png image?
I have created a program to calculate different measurements for a cylinder. Anyways, the end user has to input 3 variables.
Enter the lower radius: 6
Enter the upper radius: 5
Enter slant height: 2.236
The numbers are what "End User" would input. But I need to make it look like this when said "End User inputs the numbers.
Enter the lower radius: 6
Enter the upper radius: 5
Enter slant height: 2.236
Here is what I have for it, but I don't know what to put where.
printf("
Enter the lower radius: ");
scanf("%f", &lower_rad);
printf("Enter the upper radius: ");
scanf("%f", &upper_rad);
printf("Enter slant height: ");
scanf("%f", &slant_h);
How would I make it so that I can have someone input the length, width and height for all 3 boxes and then have it output the sum and average volume? Here's an example of what I would like:
INPUT - Enter Box 1 (Length, Width, Height): 10.1 11.2 3.3
INPUT – Enter Box 2 (Length, Width, Height): 5.5 6.6 7.7
INPUT – Enter Box 3 (Length, Width, Height): 4.0 5.0 8.0
OUTPUT – The sum of the volume is 812.806
OUTPUT – The average volume is 270.935
Here's my original code:
#include <iostream>
using namespace std;
double box(double length, double width, double height); // use double data
int main() {
double sum;
sum = box(10.1, 11.2, 3.3) + box(5.5, 6.6, 7.7) + box(4.0, 5.0, 8.0);
