Kotlin Basics ,variables and data types Tutorial 2
String variable
var myVar="Hello world"
var myVar:String
myVar="Hello World"
Integer variable
var MyVar=10
Decimal/Float variable
var myVar=1.0
For constant value variable
val myVar="Helloworld"
myVar="is not changed"
print(myVar)→output is Helloworld
Ranges
Using Double dots
val Myvar=1..10 // ranges from 1,2,3,4,.....9,10
val Myvar=1.rangesTo(10) // ranges from 1,2,3,4,.....9,10
Using downTo
val Myvar=10 downTo 1 //ranges from 10,9,8,7...3,2,1
val Myvar=10.downTo(1) //ranges from 10,9,8,7...3,2,1
Using steps
val Myvar=10 downTo 1 step 2 // ranges fro 10,8,6,4,2
Using alphabets
val Myvar="a"..."z" //ranges from a,b,c,d,.....z
val Myvar='a'...'z' //ranges from a,b,c,d,.....z
Checking a value in range variable
var MyvarinMyvar='a' in Myvar //checking a in Myvar
If else expression
val a=2
val b=3
if(a>b)
c=10
else
c=50
print(c)
or we can define same code in different way
val a=2
val b=3
var c:int=if(a>b)
a
else
b
print(c)
When and case
when(a)
{
1->print("a is 1")
2->print("a is 2")
else->print("a is unknown")
}
FOR LOOP
java
for(i=0;i<10;i++)
{
System.out.println("Hello world");
}
Kotlin
for(initializer in ranges)
for(i in 1..10)
{
println("Hello world")
}
WHILE LOOP
while(i>5)
{
print("Hello world")
i++
}
DO WHILE LOOP
do
{
print("Hello world")
i++
}
while(i>5)
RETURN STATEMENT
fun max(a;int,b int):Int
{
if(a>b)
return a
else
return b
}
or you can define return statement using equal to simply by
fun max(a;int,b int):Int
{
=if(a>b)
a
else
b
}
printing variable
print("a is larger" $a)
Return statements using apply
fun main(args:Array<String>)
{
var man=man()
man.apply{ // Using apply we can avoid man.name="Ameen" and man.age=29
age=29
name="Ameen"
}. Startrun() //here we can run function too in with we can't use this method
//we can also use with as like apply but dot function name can;t be applied at last for running function
man.apply{ // Using apply we can avoid man.name="Ameen" and man.age=29
age=29
name="Ameen"
}
}
class man{
var age:Int=1
var name:String="John"

Kotlin Basics Tutorial 1
Creating a main function in Kotlin and Java
Java
we need to create class then want to add following function
we don't need to create class,just add function
or we can add :Unit instead of void in java
For returning type int
For printing just type
/***************************************************************/
For printing Hello World in java ,we need first create a class in java then followed my main class
Java
In Kotlin we don't need to create class , just create function defining fun...and not need any semicolon for ending command, Kotlin compiler internally create class for function while running the program
Java
we need to create class then want to add following function
public static void main(String[] args){}Kotlin
we don't need to create class,just add function
fun main(args: Array<String>){}
fun main(args: Array<String>): Unit{}
fun main(args: Array<String>): Int{}
print("Hello World")
/***************************************************************/
For printing Hello World in java ,we need first create a class in java then followed my main class

public class MyClass{
public static void main(String[] args){
System.out.println("Hello World");
}
}
In Kotlin we don't need to create class , just create function defining fun...and not need any semicolon for ending command, Kotlin compiler internally create class for function while running the program

LESSON 1 Prime number up to a limit C Programming
Prime number upto a limit
Here we importing to library (stdio.h)C Standard Input and Output Library for Input and Output operations. and conio is a c header file and not part of c standard library ,it is used MSDOS compilers to console Input/Output
here we have main function and declared n,i,j,k variables with integer properties
for storing the values to n we use %d followed by &n
Next is for loop section
for(i=2;i<n;i++) →means that i=2 to n , we have n value stored in int n variable , so if n is 10 then first it start from i=2 then check 2<10 ie is true so it add 1 to i so i→3 then goto next for loop

Accessing gmail through php
first step
https://myaccount.google.com/lesssecureapps
allow access through third party apps
then use the code
<?php
/* connect to gmail */
$hostname = '{imap.gmail.com:993/imap/ssl/novalidate-cert}INBOX';
$username = 'ayman@gmail.com';//your email address
$password = 'ayman123klmn';// your password
/* try to connect */
$inbox = imap_open($hostname,$username,$password) or die('Cannot connect to Gmail: ' . imap_last_error());
/* grab emails */
$emails = imap_search($inbox,'ALL');
/* if emails are returned, cycle through each... */
if($emails) {
/* begin output var */
$output = '';
/* put the newest emails on top */
rsort($emails);
/* for every email... */
foreach($emails as $email_number) {

Electronic devices and circuits short notes with mathematical code style
This blog will help you to clear out your sure supply paper for computer science and engineering students .
http://cusatedc.blogspot.in
I created this note by referring several text book and internet sources . this note is enough for you to pass semester 3 exam. I'm sure that this is enough for your all purpose notes , just print it down , i write this blog with mathematical equation in mathematical style. If you find any error please comments it below for helping other person .I used mathjax script to forming mathematical equation if you want write mathematical equation in your comments you test it below that blog post.More over i would like you to share this tricks in this post too
here is the link for testing your code
http://cusatedc.blogspot.in/2017/11/three-transistor-configurations.html
mathjax equation begin with \( and end with \)
so for writing code we will follow like this way
\( your code \)
for writing a a/b form we use
\(\frac{a}{b}\) istead of just a/b
Now some useful code will be numbered please refer to that
1.begin and ending
\(your code\) or we can use dollar to begin and ending $$ your code $$ for separating line
2.for covering bracket full with inside code you must use \left your inside code \right
\( \left[ \frac{a}{b}\right] \)
3.some time you only need to cover an equation | this symbol , here also you just put \left followed by a dot then put right
\left. your code \right| "
for writing power use ^2
4.V1 like this we need V_1
5. for getting h21 we need to type h_{21} also for two or more power we should use h^{21}
6.For typing square root put your code inside
/sqrt{your code}
7.For making boundary use your code inside curly bracket
