Introduction to MS Visual C++ 2010 When you activate IDE for the first time, it’s time for you to make your choice: 5
Intro to MS Visual C++ 2010 Creating Unmanaged Application To build a console application that will run without .NET framework, follow these steps: 1.
2.
Open Visual Studio .NET 2010.
On the Start Page, click New Project… New, Project .
. If the Start Page isn’t visible, Choose File, 3.
4.
Select the Visual C++\Win32 Win32 Console Application from Installed Project Templates on the left and select Project type on the right.
Enter project name, for example ConsoleApplication1 , project location, for example Q: drive and click OK .
5.
Click Finish from the wizard that appears.
The wizard generates the skeleton of an unmanaged C++ application.
To build the project, follow these steps: 1.
Choose Build, Build Solution or press F7 To run the project, follow these steps: 1.
Choose Debug, Start Without Debugging or press Ctrl+F5 6

Intro to Borland C++
How to compile and execute C++ applications?
Click Start from Task bar, Select Run… and click on it Enter
cmd
command and click OK or press Enter to open an MSDOS window Change current device to Q: drive and call command H:\borlandc\bin\bc.exe
Press F10 >> Options >> Directories. Check Drive letter for Include and Library directories to be H, Drive letter for output and source directory to be Q Press F10 >> File >> New, enter the source text of your program Press F10 >> Save As… to name and save your program as a source file (.cpp).
Press F10 >> Compile >> Compile (or Alt+F9) and look at the compiler messages. In case of errors and/or warnings, you should edit and recompile your source text until “0 warnings, 0 errors, Success” is displayed Press F10 >> Run >> Run (or Ctrl+F9) to run your program.

C++ programs topics
Compiler (preprocessor) directives; Names: reserved words (keywords), standard defined and user defined identifiers; Variable declarations and data types; Executable statements; General structure of a C++ program;
compiler (preprocessor) directives using namespace std; int main() { definition (declaration) statements executable statements }
21
Elements of programming style
Spaces in a program; Using comments; Mnemonic identifiers; Arithmetic expressions. Rules for expressions evaluation: – Parentheses rule – (sub expressions) first; – Precedence rule – highest priority first; – Association rule – left or right associative operators.
22
input/output manipulators
I/O manipulators are used to control and modify data that is extracted from input stream or inserted to output stream.
I/O manipulators are active after including the following header files: #include
Input/output manipulators
endl setw(n)
Inserts the newline character into an output stream.
Controls the width of an output field.
dec, hex, oct fixed, scientific
Controls the numeric system base (10, 16, 8) used to display values.
Causes real numbers to display in decimal or in scientific notation.
showpoint
setprecision(n) left, right
Ensures decimal point and trailing zeros if necessary always to appear.
Sets the precision to
n
decimal places.
Left-adjust or right-adjust output in field.
