Multitasking Multitasking is a process of executing multiple tasks simultaneously. We use multitasking to utilize the CPU. Multitasking can be achieved by two ways: Process-based Multitasking(Multiprocessing) Thread-based Multitasking(Multithreading) 1) Process-based Multitasking (Multiprocessing) Each process has its own address in memory i.e. each process allocates separate memory area. Process is heavyweight. Cost of communication between the processes […]

Call by Value:- 1) In this actual copy of arguments is passed to formal arguments. 2) Any changes made are not reflected in the actual arguments. 3) It can only be implemented in C, as C does not support call by reference. 4) Actual arguments remain preserved and no chance of modification accidentally. 5) It […]

Data Abstraction means to represent just overview of any process not describing details. Data Abstraction may also be defined as the process of identifying only the required characteristics of an object ignoring the irrelevant details. The properties and behaviours of an object differentiate it from other objects of similar type and also help in classifying/grouping the […]

What is a File in Programming Language? File is created for permanent storage of data. It is a readymade structure. In C language, we use a structure pointer of file type to declare a file. Why we need File in Programming Language? File handling is important concept in every programming language. It is quite helpful to store data for long […]

C++ programming is to introduce the concept of object orientation to the C programming language. Object Oriented Programming is a paradigm that provides many concepts such as inheritance, data binding, polymorphism etc. TCCI Coaching Institute teach various programming Languages like C++, Java, Python etc. We conduct Online and Offline Lectures for every computer course at TCCI. Interested people can contact us […]

The process of allocating memory during program execution is called dynamic memory allocation. DYNAMIC MEMORY ALLOCATION FUNCTIONS IN C: C  language offers 4 dynamic memory allocation functions. They are, malloc () calloc () realloc () free () Syntax: 1. malloc () function is used to allocate space in memory during the execution of the program. malloc […]

Method Overriding in Java is the best example for Runtime Polymorphism. In this type of Polymorphism the Parent class reference can hold object of Parent class or any sub class (Child class) of Parent.This technique is called as Dynamic Method Dispatch.  Dynamic Method Dispatch is a technique in which the overridden method to call is resolved at the run-time […]

E.F Codd was a Computer Scientist who invented Relational model for Database management. Based on relational model, Relation database was created. Codd proposed 13 rules popularly known as Codd’s 12 rules to test DBMS’s concept against his relational model. Codd’s rule actually defines what quality a DBMS requires in order to become a Relational Database Management System (RDBMS). […]

Templates are a feature of the C++ programming language that allows functions and classes to operate with generic types. The simple idea is to pass data type as a parameter so that we don’t need to write same code for different data types. Template allows a function or class to work on many different data types without […]

Both function overloading and templates are examples of polymorphism. Function overloading is used when multiple functions do similar operations; templates are used when multiple functions do identical operations. Templates provide an advantage when you want to perform the same action on types that can be different. Function Overloading works on different type’s no. of arguments. Syntax: […]
