Hardware and Software are in many items we use in our daily lives. Name a few items in your house or office that have some sort of hardware and software. Look beyond your computer and other devices used with your computer. Thinking of the software that they may have, what does the software provide and how does it make the device/hardware better? Respond to at least two of your classmates’ postings.

 

 

 

Install the application provided with the text. You should be installing Microsoft Visual C++ 2005 (Windows Vista users will also need to install Service Pack 1 before running the program).

 

You will also need to copy the zip file that provides the C++ libraries: Libraries.zip. Please read these Instructions on downloading the zip files to your hard drive.

 

As part of this exercise you will also use the sample code below to test the application, compile the code and communicate that your application was installed and working.

 

This is the sample code:

 

#include <iostream>
#include <string>
using namespace std;

 

int main()
{
  string str1(“Alpha“);
  string str2(“Beta“);
  string str3(“Omega“);
  string str4;

 

  // assign a string
  str4 = str1;
  cout << str1 << “n” << str3 << “n”;

 

  // concatenate two strings
  str4 = str1 + str2;
  cout << str4 << “n”;

 

  // concatenate a string with a C-string
  str4 = str1 + ” to “ + str3;
  cout << str4 << “n”;

 

  // compare strings
  if(str3 > str1) cout << “str3 > str1n”;
  if(str3 == str1+str2)
    cout << “str3 == str1+str2n”;

 

  /* A string object can also be
     assigned a normal string. */
  str1 = “This is a null-terminated string.n”;
  cout << str1;

 

  // create a string object using another string object
  string str5(str1);
  cout << str5;

 

  // input a string
  cout << “Enter a string: “;
  cin >> str5;
  cout << str5;

 

system(“pause”);
return 0;
  }

 

The code above is a simple program that will output some string statements and then ask for one input and close after you enter text and then hit enter.

 

Try to change the text once you are successful and rename your source file. Play around with the strings. Report your experience and your efforts to the discussion board. Respond to at least two of your classmates’ postings.

 

 

 

How to add Libraries

 

–          Open zip file and place then in a directory on your hard drive. I recommend adding the folder called library to:

 

C:Program FilesMicrosoft Visual Studio 8

 

–          When you are done you will have the following; C:Program FilesMicrosoft Visual Studio 8library

 

–          Now right click on the computer icon on your desktop and click on properties.  You will be in the “System Information” screen.

 

–          Click on “Advanced Settings” and when prompted, click on continue

 

–          Click on the “Environment Variables” button

 

–          In the second box on the screen called “System Variables”, click on the line with “Path”. This will highlight the whole line.

 

–          Click on the “Edit” button

 

–          Go to the end of the line and add the following:

 

; C:Program FilesMicrosoft Visual Studio 8library

 

–          When ready, click “ok”, “ok”, “ok”

 

Zip File

 

Download and open the library.zip file from the classroom.

 

Unzip and extract all the files to the directory we created:

 

C:Program FilesMicrosoft Visual Studio 8
