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...

C++ Objects and Classes

C++ Object Oriented C++ Objects and Classes In object-oriented programming languages like C++, the data and functions (procedures to manipulate the data) are bundled together as a self-contained unit called an object. A class is an extended concept similar to that of structure in C programming language; this class describes the data properties alone. In C++ programming language, class describes both the properties (data) and behaviors (functions) of objects. Classes are not objects, but they are used to instantiate objects. What is a class? A class is an abstract data type similar to ‘ C structure ‘. Class representation of objects and the sets of operations that can be applied to such objects. Class consists of Data members and methods. Primary purpose of a class is to held data/information. This is achieved with attributes which is also know as data members. The member functions determine the behavior of the class i.e. provide definition for supporting various operations on data held...

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...
