Rhyous

So Windows 7 has been around in Release To Manufacturer (RTM) for since August 14, 2009.

Many have been using it in production since then. In fact, many have been using in Production since it was still in beta/release candidate form.

I have been using it for 1 month.

Quick Opinion
It is so much better than Vista and XP that it would take a novel to describe all the ways it is better. Most of them are simple things.

Anyway, please post comments on how long you have been using Windows 7 and why you like it.

Ok, so I have a great way to convert and int (or any other type) to a string using the stringstream from the standard library. This is listed here:
How to convert an int to a string in C++? (Also doubles, floats, etc…)

However, what do you do if you don’t have access to the C++ Standard Library? There is not stringstream or string so the solution in the above linked-to post won’t work.

So I have created a simple class Int.h that can do this conversion without the C++ Standard Library. Notice it is Int.h with a capital “I”.

It handles both positive and negative numbers.

Int.h

#pragma once

class Int
{
public:
	// Constructor
	Int(int inInt);

	// Desctructor
	~Int();

	// Public functions
	void intToCharArray(char inChar[]);
	char * intToCharArrayPointer();

private:
	// Members
	int mInteger;

	// Functions
	char digitToChar(int inInt);
};

Int.cpp

#include "Int.h"

Int::Int(int inInt)
{
	mInteger = inInt;
}

Int::~Int()
{
}


char Int::digitToChar(int inInt)
{
	char digit[11] = {'0','1','2','3','4','5','6','7','8','9'};
	//digit[0] = '';
	for (short i = 0; i < 10; i++)
	{
		if (inInt == i)
		{
			return digit&#91;i&#93;;
		}
	}
	return '';
}


void Int::intToCharArray(char inChar&#91;&#93;)
{
	char tmpVal&#91;11&#93;;
	int tmpInt = mInteger;
	bool isNegative = false;

	if (mInteger < 0)
	{
		tmpInt *= -1;
		isNegative = true;
	}

	short i = 0;
	while (tmpInt > 0)
	{
		int rightDigit = tmpInt % 10;
		tmpVal[i] = digitToChar(rightDigit);
		tmpInt = tmpInt/10;
		i++;
	}
	tmpVal[i--] = '';
	// tmpVal should now be the number in reverse.

	short j = 0;
	if (isNegative)
	{
		inChar[j++] = '-';
	}
	while (i > -1)
	{
		inChar[j++] = tmpVal[i--];
	}
	inChar[j] = '';
	// inChar should now be the number in correct order.
}

char * Int::intToCharArrayPointer()
{
	// Integers hold as many as 10 character, plus 1 for the null char.
	char * retVal = new char[11];
	intToCharArray(retVal);
	return retVal;
}

Here is a quick example of how to use it. Load this up in your favorite IDE/debugger.

Main.cpp

#include "Int.h"

int main()
{
	Int int1 = 1027;
	Int int2 = -2387809;

	char * charPtr = int1.intToCharArrayPointer();
	char charBuff[11];
	int2.intToCharArray(charBuff);
}

I haven’t seen it fail to convert any integers, positive or negative yet. Let me know if you see anything I could improve on.

Hey all,

This was really easy to figure out, since there is a nice WordPress discussion about it here:

Add Code to Your Site

So a quick example:

So if you want your code to show up in your post and be nicely formatted and colored, similar to how it is in your favorite IDE, then put your code in between the following lines:

[sourcecode language=”cpp”]
int main()
{
    //Code
}
[/sourcecode]

It looks like this:

int main()
{
	//Code
}

Put your cursor over the code and check out the top right icons that appear. You can simply click an icon to open the source in a text editor or copy the source to your clipboard.

By the way, you must have the “language=” tag and you must use one of the following short names for the code language:

• bash
• cpp
• csharp
• css
• delphi
• html
• java
• jscript
• php
• python
• ruby
• shell
• sql
• vb
• xml
