Computing factorials of higher order in JavaScript/C/C++
Following is the JavaScript code for computing factorials of higher order (>1000). Click here for the working code.
It doesn't involve any recursive multiplication. The underlying idea behind this is the kids way of doing multiplication.
JavaScript code
function calculate(){
var n=;//give number here
var a=new Array();
var i;
var j;
a[0]=1; //initializes array with only 1 digit, the digit 1.
var m=1; // initializes digit counter
var temp = 0; //Initializes carry variable to 0.
for(i=1;i<=n;i++)
{
for(j=0;j<m;j++)
{
x = a[j]*i+temp; //x contains the digit by digit product
a[j]=x%10; //Contains the digit to store in position j
temp = parseInt(x/10); //Contains the carry value that will be stored on later indexes
}
while(temp>0) //while loop that will store the carry value on array.
{
a[m]=temp%10;
temp = parseInt(temp/10);
m++; // increments digit counter
}
}
return a;// returns array containing the factorial
}
Here is C/C++ code
#include<stdio.h>
int main()
{
int t;
int a[10000]; //array will have the capacity to store 200 digits.
int n,i,j,temp,m,x;
scanf("%d",&t);
while(t--)
{
scanf("%d",&n);
a[0]=1; //initializes array with only 1 digit, the digit 1.
m=1; // initializes digit counter
temp = 0; //Initializes carry variable to 0.
for(i=1;i<=n;i++)
{
for(j=0;j<m;j++)
{
x = a[j]*i+temp; //x contains the digit by digit product
a[j]=x%10; //Contains the digit to store in position j
temp = x/10; //Contains the carry value that will be stored on later indexes
}
while(temp>0) //while loop that will store the carry value on array.
{
a[m]=temp%10;
temp = temp/10;
m++; // increments digit counter
}
}
printf("the number of digits %d\n\n",m );
for(i=m-1;i>=0;i--) //printing answer
printf("%d",a[i]);
printf("\n");
}
return 0;
}

Top Algorithms used in Computer Science and Engineering
Algorithm: Algos is a Greek word for pain, Algor in Latin, meant to be cold. Neither is the root for Algorithm, which stems instead from al-Khwarizmi, the name of the ninth-century Arab scholar whose book al-jabr-wa'l muqabalah developed into today's high school algebra textbook. He stressed the importance of methodical procedures for solving problems.
List of Algorithms in Wiki. It's is quite a big list. So, i have to do something else to start learning algorithms.

It is easy to Create a table in mysql by sending a query through php. Setting up the connection variables:
        $mysql_host="host";
         $mysql_dbuser="user";
         $mysql_dbpass="password";
         $mysql_dbname="database";
Connecting to database and checking:
$connect=
mysqli_connect("$mysql_host","$mysql_dbuser","$mysql_dbpass","$mysql_dbname"); if (mysqli_connect_errno()){ die ("Failed to connect to MySQL: " . mysqli_connect_error()); }
Sending Query for creating table:
$create=mysqli_query($connect,"CREATE TABLE tablename ( id INT ,name VARCHAR(15) NOT NULL, email VARCHAR(15), about TEXT)");
This creates a table with columns id, name, email and about with their respective Data types. You can check HEREÂ for various Datatypes offered in MySQL. By default column is set to NULL in mysql, if you want it to be NOT NULL it should be explicitly mentioned. Very often we would like the value of the id to be created automatically every time a new record is inserted.
Creating table with one of the columns as auto autoincrement:
$create=mysqli_query($connect,"CREATE TABLE tablename ( id INT NOT NULL AUTO_INCREMENT,name VARCHAR(15) NOT NULL, email VARCHAR(15), about TEXT),PRIMARY KEY (id)");
You won't be able to create table if you miss PRIMARY KEY (id), id should be declared as PRIMARY KEY if you want it to auto increment. Once i wasted lot of time by missing PRIMARY KEY, that is the very reason i wrote this.
Almost everyone has Facebook and Twitter accounts, and almost all of us have friends and followers that number in the few hundreds, if not thousands. But every now and then you don’t want to post personal thoughts and pictures for all to see. The interweb is now home to a bunch of resources that cater to small and most intimate groups. In in post i tell you how you can be SOCIAL, BUT PRIVATE.
