C Keywords

Declaration & Assignments


C Keywords
The C Keywords must be in your information because you can not use them as variable name
You can’t use keyword as identifier in your C programs, its reserved words in C library and used to perform an internal operation. The meaning and working of these keywords are already known to the compiler.

C Keywords List

A list of 32 reserved keywords in c language is given below:
auto
double
int
struct
break
else
long
switch
case
enum
register
typedef
char
extern
return
union
const
float
short
unsigned
continue
for
signed
void
default
goto
sizeof
volatile
do
if
static
while

Example Where and How Keywords are Used in the Program

Example:
#include<stdio.h>
 
main()
{
         float a, b;
         printf("Showing how keywords are used.");
         return 0;
}

In the above program, float and return are keywords. float is used to declare variables and return is used to return an integer type value in this program.

Python Lists

Python Lists Dealing with data in a structured format is quiet generous, and this is possible if those data are set accordingly in a specific manner. So, Python provides these data structures named ‘lists’ and ‘tuples’ that are used to organize data in  single set. Python has 6 built-in sequences and among them the most famous are “lists and tuples”. The lists are containers that hold a number of other objects in a given order. It usually puts into practice the sequence protocol and allows programmers to add or remove objects from that sequence. Each element of the sequence is assigned a number i.e. he index and the first index is 0 (zero). This versatile data-type of Python is written in a sequence of list separated by commas between expressions. Creating Lists To build a list, just put a number of expressions in square brackets. The syntax is: Syntax: lst1 = [ ] # lst1 is the name of the list lst2 = [ expression1 , …. , expression_N ] Example: #!/usr/bin/python ls...

Java Method Overriding

Java Method Overriding Declaring a method in the subclass which already exists there in the parent class is known as method overriding. When a class is inheriting a method from a superclass of its own, then there is an option of overriding the method provided it is not declared as final. The advantage of using overriding is the ability to classify a behavior that’s specific to the child class and the child class can implement a parent class method based on its necessity. There are certain rules that a programmer should follow in order to implement overriding. These are: In Java, a method can only be written in the child class and not in same class. Argument list should be exactly the same as that of the overridden method of that class. Instance methods can also be overridden if they are inherited by the child class. A constructor cannot be overridden. Final – declared methods cannot be overridden. Any method that is static cannot be used to override. The return type must have to be the...

C++ Data Abstraction

C++ Data Abstraction Object oriented programming offers various features to write programs with various concepts that help to minimize problems and increase flexibility in program. One of the features of object oriented programming is Data abstraction. In this chapter you will learn about how the concept data abstraction is carried out within the C++ program. What is Data abstraction? Data abstraction allows a program to ignore the details of how a data type is represented. Abstraction (derived from a Latin word  abs , meaning away from and  trahere , meaning to draw) refers to the act of representing essential features without including the background details or explanations. C++ classes use the technique of abstraction and are defined as a list of abstract attributes such as width, cost, size etc and functions to operate on these attributes. They put in a nutshell all the essential properties of an object that are required to be created. The attributes are therefore called...
