Elementary Features of BASIC and C Programming
- Knowledge Canvas
BASIC
language:
BASIC
stands for Beginners' All-purpose Symbolic Instruction Code. BASIC is a family
of general-purpose, high-level computer programming language that was designed
by John G. Kemeny and Thomas E. Kurtz in 1964.
Syntax:-
10 HOME
20 SWEET
30 GOTO 10
Features of
BASIC language:
1.BASIC
language is very easy for beginners to use. A user having less knowledge of
Mathematics and Science can also program in BASIC language.
2.BASIC
is a general-purpose, high-level, structured programming language.
3.BASIC
allow the creation of Loops.
4.This
language allows input from the keyboard.
5.BASIC
access menu-driven application.
6.It
allow Built-in and user-defined functions.
7.BASIC
contains various system commands.
8.It
provides a clear and friendly error message.
9.BASIC
support in most of the operating system.
10.BASIC uses numbers at the beginning of each instruction.
11.BASIC
was interpreted: a BASIC program was executed line by line
12.For
small program BASIC respond quickly. The small size and simplicity of BASIC made it
popular in the early personal computer.
13.For
writing program in BASIC language users haven't required an understanding of
computer hardware.
14.Subroutine
features are available in BASIC.
15.BASIC
allow advanced features to be added for advanced users.
C language:-
C
is a general-purpose, procedure-oriented system programing language, developed
by Denis Ritchie for creating system applications that directly interact with
the hardware devices. C language is known as mother language because most of
compiler written in C language and most of the modern programming language
follow the C syntax.
Syntax:-
#include <stdio.h>
int main()
{
printf("Hello C Programming\n");
return 0;
}

Feature of
C:-
1.
Procedural language:- Procedure
means a series of steps for the program to solve the problem. C is a procedure
Oriented Programming language (POP), so C has some characteristics-
i. Top-down approach.
ii.
C uses the set of instructions to inform the computer what to do.
iii.
It doesn't have a data hiding option.
iv.
As a procedural language C breaks the
program into functions, data structures, etc.
V.
In C, variables and function prototypes must be declared before being used. It
is a global declaration which are freely accessed from function to function in
the system.
2.
Middle-level language:- C is called
middle-level language because it is
a bridge between a machine-level language and high-level
languages. A user can use C language for system programming as well as
application programming.
3. Machine
independent or portable:- When a C programming
written in a particular computer can be compiled and executed on any other
machine with a little change or no change. So, it is a Machine independent or
portable language.
4. Simple:- C language
is simple because it divides the program into functions. C provides rich library
functions and data types.
5. Fast and
Efficient:- C is a middle-level language. So it provides programmers access to
direct manipulation with the hardware. This feature makes C language efficient.
As
C is a statically typed language, it is faster than dynamically typed
languages.
6. Rich
library:- C has a lot of built-in functions which help to write programs easily.
7. Memory
management:- C support dynamic memory allocation. By using calloc(), malloc()
function users become able to allocates a block of memory on the heap and we can free the memory by
free() function.
8. Pointer:- The pointer is a variable that can store the address of another variable. Pointer directly
interacts with the memory address. The pointer is a very important feature of C
programming. We can't allocate dynamic memory without the pointer.
9. Recursion:-
Recursion is
a process in which a function directly or indirectly calls itself, this function
is called the recursive function and the call is a recursive call. Recursion enables
us to use the method of backtracking.
10. Extensible:-
As C can
easily adopt new features, it is extensive.
11. Case
sensitive:- C is a case sensitive language because it treats uppercase and
lowers case letter differently. As C is case sensitive all keywords, functions,
instructions are written in lower case letters.
12. Rich set
of built in operators:- It supports a rich set of built-in operators. The operator is a symbol
that tells the compiler to perform a certain mathematical or logical operation.
Arithmetic operator, logical operator, conditional operator, relational
operator, bitwise operator, and many other operators are supported in the C program.
13. General
purpose language:- C is a general-purpose language because it is used for writing
many different kinds of applications. It is not specialized for a particular
domain.
14. structured
programming language:- Structure means to break a program into part or block. We break the C
program by using functions so that it may be easy to understand and modify.
15. Compiler
Based:- With-Without
compilation no C program can be executed.
16. Statically
type:- statically
type language Means the type of variable is checked at the time of compilation
but not at run time. C is a statically typed language.
17. Modularity:-
The concept
of storing code in the form of libraries
for further future uses is known as modularity. C has its own function to solve
a particular problem.
Example:-we
can use a particular function by using a header file stored in its library.

Difference
between BASIC and C language:
1. The main difference between BASIC and C programming language lies in syntax.
2.
BASIC is interpreted where C is compiled.
3.
BASIC is slow and easy to handle and C is fast and difficult to learn.
4.
BASIC does not support structured programming, C support structure programming.
5. The early version of BASIC does not support creating large program, C support to
create a large program.
6.
BASIC doesn't provide pointer, C provide pointer
7.
C support dynamic memory management but BASIC doesn't support
