In real life, I am very lazy and I made it my coding style I always try to make a reusable component that’s my USP for programming which saves my time and extra working both.

Putchar write a character to standard output (monitor). It takes argument as character and returns its integer form without sign. If a writing error occurs, EOF is returned and the error indicator (ferror) is set.

Getch

Getch takes input a character from keyboard. Getch is different from scanf because user need to press enter explicitly to complete input process but getch intensely return pressed key ASCII.

Some people used getch to hold program output because when getch excuted it wait for a character and until user press a character next statement would not get executed.

Switch Case C Language

Switch Case

A switch case is uncomplicated solution/alternate of complicated nested if-else. It is useful when there is a need check to arise multiple possibility on single variable like print day of the week name based on the given day number. Best for long if statements that compare a variable to several "integral" values ("integral" values are simply values that can be expressed as an integer, such as the value of a char).

Above figure is showing syntax of switch case. In syntax break and default are in bracket, which means they are optional. You can use more than one case without using break. If break is omitted, then all the ca

Lucas Series

Lucas Numbers similar to the Fibonacci series that often occurs when working with the Fibonacci series. Edouard Lucas (1842-1891) (who gave the name "Fibonacci Numbers" to the series written about by Leonardo of Pisa) studied this second series of numbers: 2, 1, 3, 4, 7, 11, 18, .. called the Lucas numbers in his honour. On this page we examine some of the interesting properties of the Lucas numbers themselves as well as looking at its close relationship with the Fibonacci numbers. The following page generalises further by taking any two starting values.

Looping With Cursor SQL Server

Cursor is an database object which is use when there is a need to process table record row by row . you can access each field of your table at record by record.In relational databases, operations are made on a set of rows. For example, a SELECT statement returns a set of rows which is called a result set. Sometimes the application logic needs to work with a row at a time rather than the entire result set at once. In T-SQL, one way of doing this is using a CURSOR. For example when we want to get record from one table and need to insert into another with performing some logic or some conditions .For example if we want to get value from one table row by row and need to perform some logic over that and update /insert into another table then we can use cursors. Cursor basically works as for/While loop.

What is automatic type promotion in c

Q : In the following declaration statement:

char c=’A’;
Variable c stores one byte of memory space while character constants ‘A’ stores one byte memory space. How one byte variables can stores two byte character constant? What is automatic type promotion in c?

Solution :

Character constant reserve two byte of memory space to represent octal or hexadecimal character constant but char variable stores only its one byte ASCII value.

In C language, char type is used to store a 1 byte integer. When you assign 'A' to char c, you are not assigning the letter A itself into memory. Rather, you are assigning the number (integer) representing the A character. Each letter has a digit that represent it. . Remember that unlike humans, computers cannot understand letters. That's why we need a way to translate them into digits. To do this we use differnet coding styles like: ASCII, UTF-8, etc If your machine use ASCII coding then the value assigned to char c would be 65 (0x41 hex). As you may notice, 0x41 is one byte and can be stored in your char variable.

Automatic type promotion

Some data types like char , short int take less number of bytes than int, these data types are automatically promoted to int or unsigned int when an operation is performed on them. This is called integer promotion. For example no arithmetic calculation happens on smaller types like char, short and enum. They are first converted to int or unsigned int, and then arithmetic is done on them. If an int can represent all values of the original type, the value is converted to an int . Otherwise, it is converted to an unsigned int.

int main()

{

char a = 30, b = 40, c = 10;

char d = (a * b) / c;

printf ("%d ", d);

return 0;

}

At first look, the expression (a*b)/c seems to cause arithmetic overflow because signed characters can have values only from -128 to 127 (in most of the C compilers), and the value of subexpression ‘(a*b)’ is 1200 which is greater than 128. But integer promotion happens here in arithmetic done on char types and we get the appropriate result without any overflow.

Consider the following program as another example.

Define void data type and write any three use of it.

Q : Define void data type and write any three use of it.

The data type void actually refers to an object that does not have a value of any type. Void is also used to indicate when a function does not return a value or no argument. Such a function is used for its side effect and not for its value. In the function declaration and definition, we have indicated that the function does not return a value by using the data type void to show an empty type, i.e. no value. Similarly, when a function has no formal parameters, the keyword void is used in the function prototype and header to signify that there is no information passed to the function.

What is dangling pointer in C? What is wild pointer in C? Give example.

Q : What is dangling pointer in C? What is wild pointer in C? Give example?

Dangling Pointer

Dangling or wild is a pointer which does not point valid object. When a pointer has declared it must be assign a valid address memory address otherwise it will point some location which is not valid. These are special cases of memory safety violations. More generally, dangling references and wild references are references that do not resolve to a valid destination.

What are merits and demerits of array in C?

Q : What are merits and demerits of array in C?

Why we need an array.

We need array when there is a need to process more than data with similar type. For example

Taking marks of 10 student needs of ten integer
Taking name of more than one character
Structure record and many more

Criteria mentioned above can also be achieved through variable , but variables have following drawback which lead to use array instead of Variable.

Each variable must has unique name which increase complexity when a large number of variables need to make.
Each variable load in memory at random order. So if you want to process all variable then you need to process each variable individually because allocation of space is not continuous.

For understand the above point you need to imagine a real life example.

Two close friend group decided to watch a movie and they follow two different approaches as follows

Friends in Group one purchase ticket individually without any coordination between them for seating arrangement
Friend in group two book seats continuously i.e. seats no 1 to 10.

So Group two can make better communication than group one. In same way array works.

Advantage

Continuous memory allocation.
Process a collection of similar data type.
Can be used to make data structure like stack,tree,queue etc.
Easy to visit each element using index.

Disadvantage

Static memory allocation
Due to static memory allocation number of element cannot be increase nor decrease at run time.
The elements of array are stored in consecutive memory locations. So insertions and deletions are very difficult and time consuming.

Call by value

The call by value method of passing arguments to a function copies the actual value of an argument into the formal parameter of the function. In this case, changes made to the parameter inside the function have no effect on the argument.

Customized web page print using Java Script

Printing a webpage is another important aspect of web development. If you skip this section then when your user will be print a page then it will print as it is, which not good for all case because we add a lot of formatting images on webpage. So all the things on the page will get printed that will be worse.

Customizing web page output is good practice to make a webpage. Because what we see on web page we don’t need to take output on paper same format so customization is mandatory.

Following example will print table as with custom header.

Roll	Name	City
101	Sona	Vns
102	Amit	Alld
103	Sumi	Alld
104	Rakesh	Vns
