How To Increase Internet Speed without the use of any software

Posted by Tushar Bedekar

Many times we find that our internet speed is slow and we get tired to use it for a long time. Now here is the solution. Actually.Actually what our PC or Our Laptop reserves some amount of the internet bandwidth(nearly 20% default). And now if we make this reserved band width to a zero than the internet speed can be increased by the certain amount.So in order to increase your internet speed just follow the steps given below:-

Steps:-


  • First of all open run just by pressing the keyboard shortcut(windows key +R)
  • Then enter the command given below:-                                              gpedit.msc
  • Now a windows opens having the name (local group policy editor)
  • In the left most corner it has been written (administrative temp lets)
  • Inside that administrative temp-lets click on the network.
  • Now in the right hand side window you will find QoS packet scheduler.
  • Now double click on that.
  • After Double clicking it you will find the option limit reversible bandwidth.
  • Again Double click on that.
  • you will find the option bandwidth limit (%) in which 20 or any other value is being written.
  • Make it zero and than click apply.
  • Now you have done.
  • Then restart your Browser you will find some speed has been increased.

Fibonacci series by Recursion in c

Posted by Tushar Bedekar

Introduction:-

http://www.allaboutcomputing.net/
Recursion is the process of repeating items in a self-similar way. In other words recursion is a process in which a same set of a statement/expressions are executed large no of times in such a manner that after the execution of a certain set of a statement/expression, again the same set of a statement/expressions are being executed until the condition is satisfied. Generally this kind of a process takes place in the in functions in which a function calls itself. The following is the syntax of the recursive function:-
void recursion()
{
   recursion(); /* function calls itself */
}

int main()
{
   recursion();
}
http://www.allaboutcomputing.net/Actually most of the programming languages support recursion an C programming language is one of them i.e., a function to call itself. But while using recursion, programmers need to be careful to define an exit condition from the function, otherwise it will go in infinite loop.
Recursive function are very useful to solve many mathematical problems like to calculate factorial of a number, generating Fibonacci series, etc.

Program me:-


/* Fibonacci by Recursion */
#include<stdio.h>
http://www.allaboutcomputing.net/
int fib(int); int main() { printf("Type any value : "); printf("\nNth value: %d",fib(getche()-'0')); return 0; } int fib(int n) { if(n<=1) return n; return(fib(n-1)+fib(n-2)); }

C Programming to Explain Type Casting

Posted by Tushar Bedekar

Introduction:-

Type casting is a way to convert a variable from one data type to another data type. For example, if you want to store a long value into a simple integer then you can type cast long to int. You can convert values from one type to another explicitly using the cast operator as follows:


Program me:-

#include< stdio.h>
#include< conio.h>
int main( )
{
int n,i,j,fact;
float sum=0;
clrscr();
for(i=1; i<=7; i++) { fact=1; for(j=i; j>=1; j--)                       // to find the factorial
fact=fact*j;

sum=sum+(float)i/fact;
}
printf("\nSum : %f",sum);
getch();
return 0;
}

Modifiers in C Programming Language

Posted by Tushar Bedekar
C Programming Modifier
As We Have discussed in the last article about C Programming   the data types have some modifiers preceding them. The use of these modifiers changes the meaning of the base type.

The memory in the computer is organized in terms of units called bytes. One  byte consists of 8 bits and bit is a smallest unit of memory.

Need of Data Modifiers:

The Need of modifiers can be understood by the help of following.Let us take an example of a Program where we need to input the “Salary” of “Employees” in a team. This program will accept the salary as an input from user and then calculate the Income Tax of that user. We use “int” to store the Salary of the employee as we are assuming that the salary will be in “Whole Numbers”.
C Programming Modifier

An integer data type takes 2 Bytes of Memory and we are aware that the Salary of any of the employee can not be “Negative”. We are using “2 Bytes” to store the memory of an Employee and we can easily save 1 Byte over there by removing the “Signed Part” in the integer. This positive value can easily be stored in “1 Bye Int” This leads us to the user of Data Type Modifiers.

Types of Data Modifiers in C:

Basically c programming language consist of 3 basic modifiers.The modifiers are listed below :


Signed Type Modifier:



All data types are “signed” by default. Signed Data Modifier implies that the data type variable can store positive values as well as negative values.


For example, if we need to declare a variable to store temperature, it can be negative as well as positive.

C Programming Modifier
signed int temperature;


Or


int temperature;



Unsigned Type Modifier:



If we need to change the data type so that it can only store only store positive values, “unsigned” data modifier is used.


For example, if we need to declare a variable to store the salary of an employee as explained above, we will use “Unsigned” Data Qualifier here.


unsigned int salary;


Long Type Modifier:


Sometimes while coding a program, we need to increase the Storage Capacity of a variable so that it can store values higher than its maximum limit which is there as default. In such situations or programs, we need to make use of the “long” data type qualifier. “long” type modifier doubles the “length” of the data type when used along with it.

C Programming Modifier
For example, if we need to store the “annual turnover” of a company in a variable, we will make us of this type qualifier.


long int turnover;


This variable will take 4 Bytes in memory.



Short Type Modifier:



A “short” type modifier does just the opposite of “long”. If one is not expecting to see high range values in a program and the values are both positive & negative.

C Programming Modifier
For example, if we need to store the “age” of a student in a variable, we will make use of this type qualifier as we are aware that this value is not going to be very high.


short int age;


This variable will consume only 1 Byte in memory.



Example

We can apply the above mentioned modifiers to integer (int) and character (char) base types.


1. Integer Type Modifiers:



* We can use all the above mentioned Type Modifiers for int data type in C Language

* Short int and long int are also termed as short and long respectively.
* Int is signed & unsigned by default.


2. Character Type Modifiers:



* Variables of type char consume 1 byte in memory.

* Char can be signed or unsigned only.
* They have a range of -128 to 127 and 0 to 255 for signed & unsigned respectively.


3. Float Type & Double Type Modifier:



There are 3 types of float type modifiers as given below:

C Programming Modifier


* float

* double
* long double

Double is same as long float. Float type occupies 4 bytes of memory. Type double occupies 8 bytes. Long double occupies 10 bytes. The exception to this is long double, which modifies the size of the double data type to 10 bytes. Please note that in some compilers this has no effect.



Note: We may use long modifier with double data type but it cannot be used with float, i.e. long double is allowed but long float is not allowed because long float is equal to double.
