Infix to postfix converstion

 Infix to Postfix Conversation 

Procedure :-

1.Scan the infix string from left to right .

2.Initialise an empty stack 

3.If the scanned character is an operand,add to the postfix string .

4.If the scanned character is an operator, and if the stack is empty push the character to stack.

5.Repeat 4 steps till the characters are scanned.

6.After all characters are scanned, we have to add any character that the stock may have to the postfix string .

7.If stock is not empty add Top stack to postfix string and pop the stack.

8.Repeat the steps as long as stack is not empty.

Conversation Infix to Postfix

Ex:-

(a+b)*(c-d)

in put out put
(a+b)*(c-d)
(+b)*(c-d) 
b*(c-d)
*(c-d)
*(-d) 
*(-)
*
Empty
- 
a
a+
ab+
ab+c
ab+cd
ab+cd-
((ab+)(cd-))

History of C language

History of C language C Language history is very interesting which knowing it C programming language was developed by Dennis Ritchie at bell laboraties of AT and T(American Telephone & Telegraphi), which located at the U.S.A.     Dennis Richie is know as the founder of C language . It was developed to overcome the problem which were facing in previous language such as B,BCPL,etc.,     Initially ,c language was developed to be used in UNIX operating system . Later on it inherits many features of previous language such as B and BCPL. Year        programe               Introduced by 1960   ALGOL60 (Algorithmic language) international committee 1963 CPL(combined  programing language) Cambridge university 1967 BCPL(basic combined programing language Cambridge university(Martin Richard) 1970 B language  Kenthompson 1972 C language  Deniel ...

  Algorithm :-      An algorithm is a finite set of instructions (or) logics , written in order to accomplish a certain predefined task it is not the complete code or program which can be expressed either  as an informal high level description as a pseudo code or using a flowchart.   >> From the data structure point of view, following a some important categories of algorithm. >>Search :- algorithm to search an item in a data structure . >>Sort :-algorithm to sort in a certain order >>Insert :-algorithm to insert items in a data structure. >>Update :- algorithm to update an existing items in a data structure. >>Delete :- algorithm to delete an existing item from the data structure. Unambiguous :- Algorithm should be clear and unambiguous. Each of its step (or phase) and their input, output should be e clear must lead to only one meaning. Input :-An algorithm should have 0 or more well-defined inputs >>Output :-An...
