C/C ++
Programming, eh? We all know it, don't
we. And today is the world of JAVA, VB6, SQL, etc. So why C/C++? Aren't
they outdated? This must be some of the questions in your mind. That's
the main reason for me writing on this topic. Nothing can survive unless
it has a strong foundation. And let me make it clear right now that C is
the foundation on which you can build up your career in computer
programming.
Let us start with the subject now.
Some Properties of C Language
The increasing popularity of C is due to its many desirable qualities.
It is a robust language whose rich set of built-in functions and
operators can be used to write any complex program. The C compiler
combines the capabilities of an assembly language with features of a
high-level language and therefore it is well suited for writing both
SYSTEM SOFTWARE AND BUSINESS PACKAGES.
It has only 32 keywords and its strength
lies in its built-in functions.
C language is well suited for structured programming, thus requiring the
user to think of a problem in terms of function modules or blocks.
Another important feature of C is its ability to extend itself. A C
program is basically a collection of functions that are supported by the
C library. We can continuously add our own functions to the C library.
We Begin Our Work
Consider SAMPLE C PROGRAM
main()
{
/*......printing begins.....*/
printf("I see ,I remember");
/*......printing ends.......*/
}
- The first line informs the system that
the name of the program is 'main' and the execution begins at this
line. The main() is a special function used by the C system to tell
the computer where the program starts. There should be exactly one
main() in the program. The empty parentheses indicates that function
main has no arguments.
- The opening brace'{' marks the
beginning of function main and the closing brace indicates the end
of the program.
- The lines between the /* & */ are
all the comment line statements. The statements are never compiled
and are for the sake of the programmer himself and for others to
understand.
The printf() is a predefined ,standard C function for printing the
output. Predefined means that it is a function that has already been
written and compiled, and linked together with our program at the
time of linking.
Whatever is specified within the '(" ' & '")' will be
printed on the output as it is.
We have seen that a basic C program has
following parts
main() <------------Function name
{ <------------Start of program
....
... <---------Program statements
} <------------End of program
This was just a primer to get you
interested in this subject. I look for you company in this journey for
excellence in C/C++.
