Here i am going to explain how you can read strings and data like integer float long double long and other data types from keyboard and save it to a variable in python.The python code is simpler than java.Java program need more steps to read a value or string from keyboard.
You can run this code by saving the program to c:\python27\program.py and open the command prompt and type the above code ( in screen shot ).

Java Script To Start A File Download Automatically After 30 Seconds Or Page Load

You can initialize automatic downloads after some waiting time. Optionally you may add a count down screen to start download here i am explaining two ways to start download after 30 seconds.You can also add "click here if the download doesn't start automatically" using ordinary links.
In firefox and google chrome it is easy to do this auto download

Code 1 - You may assign waiting time by replacing 30 with your assigned time in seconds

<html>
<title> Title of your download page </title>
<meta http-equiv=REFRESH CONTENT="30; url=http://full path of your file">
<body>
If the download doesn't start automatically<a href="http://full path">click here</a>.
</body>
</html>

Some browsers are not supporting the above codes so you may use my second code to start download automatically

Code 2 Waiting time is in micro second 100 micro second = 1 second

<script type="text/javascript">
var t=setTimeout("download()",30000)
function download()
{
window.location = 'full path of your file';
}

</script>

C Program For Binary Search With Flowchart

Aim
To write a c program to perform binary search

Program
#include<stdio.h>
main()
{system("clear");
int n,a[100],i,j,temp,s,low,high,mid,flag=0;
printf("Enter The limit");
scanf("%d",&n);
printf("Enter The number\n");
for(i=0;i<n;i++)
{scanf("%d",&a[i]);
}
for(i=0;i<n;i++)
{
for(j=i+1;j<n;j++)
{if(a[i]>a[j])
{
temp=a[i];
a[i]=a[j];
a[j]=temp;
}
}
}
printf("The sorted list of numers\n\n");
for(i=0;i<n;i++)
printf("%d\n",a[i]);
printf("\nEnter The number to be searched");
scanf("%d",&s);
low=0;
high=n-1;
while(low<=high)
{mid=(low+high)/2;
if(s==a[mid])
{
printf("The numberis found at The position%d\n\n",mid+1);
flag++;
break;
}
else if(s>a[mid])
low=mid+1;
else
high=mid-1;
}
if(flag==0)
printf("The number is not found \n\n");
}
