History of C language

By
The C language was developed at AT & T (American Telegraph & Telephone)  Bell Laboratories in the early 1972's by a system programmer named Dennis Ritchie. It was written originally for programming under an operating system called UNIX which itself was later rewritten almost entirely in C. Its name encrypted as C, derives from the fact that it is based on an earlier version written by Ken Thompson, another Bell laboratories system engineer. He adapted it from a language that was known by the initials BCPL (Basic Combined Programming Language). Thompson derived his programming language name as B, the first of the initials BCPL. When the language was modified and improved to its present state, the second letter of BCPL, C was given to it. The C language is often described as a middle level language. It permits programs to be written in much the same style as that of most of high-level programming language. It also interacts with the inner workings of the computer. The American National Standards Institute (ANSI) has established certain standards for C which is known as ANSI C in addition to the original version of C developed by Dennis Ritchie. The another popular version of C is Turbo C.

Object Oriented Programming

By
Object Oriented Programming Programming paradigm that represents the concept of "objects" that have data fields (attributes that describe the object) and associated procedures known as methods Programming methodology based on objects, instead of just functions and procedures Focuses on data rather than process As individual objects can be modified without affecting other aspects of the program, it is easier for programmers to structure and organize software programs Easier to update and change programs written in object-oriented languages Simula was the first object oriented programming language Eg: C++, Java, etc. Features of OOPS Objects Referred as instance of class Basic run-time entities in an object-oriented system a person, a place, a bank account, a table of data, etc can be an object They occupy space in memory that keeps its state  Each object contains data and code to manipulate the data  Classes Blue print or prototype  which defi

How structure elements are stored?

By
  The elements of a structure are always stored in contiguous memory locations. This can be illustrated as void main() {     struct student      {      int roll;      float marks;      char remarks;   };   struct student st={200,60.5,'P'};   printf("\nAddress of roll=%u",&st.roll);   printf("\nAddress of marks=%u",&st.marks);   printf("\nAddress of remarks=%u",&st.remarks);   getch(); } Output: Address of roll=65518 Address of marks=65520 Address of remarks=65524                  st.roll               st.marks                          st.remarks 200 60.5 ‘P’               65518             65520                               65524

How containership is different than inheritance ?

By
               Inheritance is the mechanism of deriving properties of one class into another. While containership is mechanism in which one class contain objects of other classes as its member.                     class alpha{_ _ _ _ _ };                     class beta{_ _ _ _ _ };                      class gamma                      {                         alpha a;                         beta b;                       _ _ _ _ _ };            All objects of gamma class will contain the objects a and b, this kind of relationship is called containership or nesting.
