Query String PHP

Query string is part of an URI which is use to pass some information in URL. Information pass by a query string can be used by server or client by java script or any server side language. Query string is one most powerful method to pass additional information about web processing application but query string is not recommended to pass sensitive information because query string put flat text which can be read by anyone.

Dynamic Memory allocation C language

Memory is storage unit which every program need for their operation. When you run your program then a request is made to OS for memory allocation. There are two types of memory allocations are used in programming.

Dynamic

Static memory allocation is fix allocation. It cannot be change during run time. Static memory allocation is better option in case when we know exactly how much amount of memory need. For example holding roll number marks of student etc.

IDENT_CURRENT SQL Server

IDENT_CURRENT return last inserted identity field value from any session any scope table.

One most interesting things which surprise me while I had used this first time. Which is follows

You can get SQL server generated identity value which inserting row, means it is not necessary that identity value only can get after save a row. Not at all!

You can use this feature while creating some userid and roll number type field in many applications.

i.e: 10000001,2000829 etc.

CREATE TABLE dbo.stu(

ID INT IDENTITY NOT NULL PRIMARY KEY,

Roll varchar(20),

Name VARCHAR(40) NOT NULL

City VARCHAR(40) NOT

A pointer is a special type of variable which hold physical address of a non pointer variable.Symbol * is used to make a pointer variable.

Call reference is an example of pointer , in which a variable physical address pass to a function and any change made inside of function direct effect actual value of passed variable due to pointer.

Structure Example

Q : What is meant by structure data type? How do we reference the elements of a structure?
Give example of how a value of a structure can be assigned to another structure.

Solution :

A structure is user defined data type which is used to store record based data. Structure is useful when there is a need to process record type data for example student record which is a combination of more than variable (roll,name,class,marks etc). Structure encapsulates more than one variable into a single logical unit. Without structure, processing of record based data is not an easy task. Programmer need to declare many variables with different name. Which increase complexity?
