C /C++ Programming Language
• C++ is an extension of C
• Support procedure-oriented and object-oriented programming
approach
• Invented by Bjarne Stroustrup in 1980
HOW COMPUTER RUN A PROGRAM
Edit : Source code ( type the program)
Compile : If no syntax errors -> Object Code
Link : Link to library function -> exe module
Run : Output ( Check for any semantic errors)
Source Code
Preprocessor
Modified Source Code
Compiler
Object Code
Linker
Executable Code

Manipulator ( # include <iomanip.h>)
1. “\n” : Advances the cursor to the beginning of the next line
e.g cout << “Mummy The Return\n\n”;
cout << “The Sixth Sense << endl;
Output: Mummy The Return
The Sixth Sense
2. endl : Advances the cursor to the beginning of the next line. Forces any data
remaining in the archive buffer to be written to the file.
Same as \n
3. “\t” : Horizontal tab
e.g. cout << “Mummy\tThe\tReturn\n\n”
Output: Mummy The Return
Manipulator

4. setw (n) : sets the stream’s internal field width variable to n. This setting
remains
in effect only for the next insertion.
e.g cout << setw(10) << 567 << setw(30) << "Pearl Harbour";
Output ^^^^^^^567^^^^^^^^^^^^^^^^^Pearl Harbour
5. setfill (‘?’) : This parameterized manipulator sets the stream’s fill character. The
default is a space. This setting remains in effect until the next
change.
e.g cout << setfill (‘*’) setw(5) << 567 << setw(20) << “Pearl
Harbour”
Output **567*******Pearl Harbour

Simple C++ Program
# include <iostream.h>
# include <iomanip.h>
// Aturcara ini akan mencetak sahaja (Penggunaan arahan cout)
void main ( )
{
cout << “Welcome to KUTKM \n”;
cout << “ MELAKA BANDARAYA BERSEJARAH”;
}
A Simple Program
Output:
Welcome to KUTKM
MELAKA BANDARAYA BERSEJARAH
7
Welcome to
KUTKM
MELAKA
BANDARAYA BERSEJARAH
Exercise 1:
Write a complete program to print the following output:

#include <iostream.h>
#include <iomanip.h>
#define P 100
void main()
{
cout << "WELCOME TO UTM" << setfill('$') <<
setw(40);
cout << “GOOd luck to ALL\n";
cout << " " <<P <<"\n";
cout << "SELAMAT\tMAJU\tJAYA" <<endl <<endl;
}
Output:
WELCOME TO UTM$$$$$$$$$$$$GOOd luck to ALL
