Answer In all programming languages, it is a practice to declare variables along with their types. The reason for doing so is that when a variable is declared, the compiler reserves space for it in the memory.
It is also a practice to declare them along with the type of data they are intended to hold or store…
The arithmetic operators manipulate numerical values and the assignment operator stores a value to a variable.
Answer It is often a requirement of a program to group items of same type say sales of an item X in Northern Region in one element to achieve preciseness and to make programming clearer, therefore sometimes repetitive data structures like array are used to group items of same type. Also, separate declaration of data element of similar type would make a program long and difficult to understand.
Answer Record data structures , as the name suggests are the objects that implement a real life record for example the record would typically represent a students attributes ,like his roll number ,name , date of birth and marks obtained in a particular subject or subjects . Here various attributes like name, roll number, date of birth etc are different types of data elements, but they are grouped together through record data structures.
Answer If a programmer needs to implement programmatically a real life scenario, like maintaining a file of different students, and then perform operations like calculating their average age, or arranging their names alphabetically then he needs to combine repetitive and record data types to achieve the desired logic.
The packed attri
7. What are the four attributes of a variable
Answer Four attributes are currently defined for variables: aligned, mode, packed, and section.
This attribute specifies a minimum alignment for the variable or structure field, measured in bytes.
This attribute specifies the data type for the declaration---whichever type corresponds to the mode.
The packed attribute specifies that a variable or structure field should have the smallest possible alignment---one byte for a variable, and one bit for a field, unless you specify a larger value with the aligned attribute.
Normally, the compiler places the objects it generates in sections like data and bss. Sometimes, however, you need additional sections, or you need certain particular variables to appear in special sections, for example to map to special hardware. The section attribute specifies that a variable (or function) lives in a particular section.

Python Programming Language. Python programming language includes various features of modern programming languages such as it is an interactive, explained, and programming language which works on objects. Additionally, it includes programming exception, components, extremely elevated level of dynamic data types, brisk typing and class level functionalities.
The various programming languages available for computer programming are classified according to the paradigm in which they operate. Each programming paradigm is different in style, concept and methodology from others. Different paradigms are suitable for different purposes egg – object oriented paradigm considers any program written as a collection of various objects that interact with each other, database programming paradigm is ideal if the program is intended to handle large amount of data and logic and constraint based programming is the most suited for search problems.
Java is an object-oriented programming language created in 1995 by Sun Microsystems for the development of software applications and interactive programs or applets which are commonly used in the internet for animation purposes. In today's evolution in mobile industry, Java contributes more advancement in the making of mobile applications and software.
The main reasons for this were the cost and the lack of knowledge about computers to the common man. In those days development of programming languages were at the initial stages. Because of the cold war the computer rooms were heavily guarded and research on software engineering was not given much importance.
The collections of objects with identical characteristics are collectively known as a class. It is the basis of modularity and structure in an object oriented program. We can design our own classes and create instances of these and then assign them to variables.
void setTime (int hh, int mm, int ss) therefore can be accessed by another class to set the hh, mm, ss. Only the same class however can set the variables hour, minute, second.
c) A constructor is a default method that initiates the variables hour, minutes, seconds.
Though every language is built on the common ground of communicating “Efficiently and Effectively” with the machine, each language has its own merits and demerits. Some were developed with a specific purpose, some with a specific business application, some for scientific purposes, and some to overcome the demerits of other languages.
