+# Channel operators: Send and Receive
+
+Example demonstrates send and receive channel  operators in Go programming language. Channel works with two principal operations, one is sending and another one is receiving.
+The direction of `<-` operator  indicates whether the data is received  or send.

+
+```go
+/*
+* Send operation is used to send data from one goroutine to another with the help of a channel. Values like int, float64, and bool can  be safely send through a channel because      * they are copied, and there is no risk of accidental concurrent access of the same value. Similarly, strings are also safe to transfer because they are immutable. But sending   
+* pointers or reference like a slice, map, etc. through a channel are not safe because the value of pointers or reference may change by sending goroutine or by the receiving    
+* goroutine at the same time and the result is unpredicted.  So, when you use pointers or references in the channel you must make sure that they can only access by the ONE goroutine * at a time. For example, *Mychannel <- element* indicates that the data(element) SEND to the channel(Mychannel) with the help of a <- operator.
+*/
+
+/*
+* The receive operation is used to receive the data sent by the send operator.
+* Here, *element := <-Mychannel* indicates that the element RECEIVES data from the channel(Mychannel).
+* You can also write a receive statement as: *<-My channel*

+# Channel 
+
+Example demonstrates creating channel in Go programming language. Channel is a medium through which a goroutine communicates with another goroutine.
+By default, channel is bidirectional, it can only  transfer data of the same type.
+Click [here](https://tour.golang.org/concurrency/2) to learn more
+
+```go
+/*
+ * A channel is created using chan keyword.
+ * You can also create a channel using make() function using a shorthand declaration. 
+ */
+package main
+
+import "fmt"
+
+func main() {
+
+	// Creating a channel
+	// Using var keyword
+	var mychannel chan int
+	fmt.Println("Value of the channel: ", mychannel)
+	fmt.Printf("Type of the channel: %T ", mychannel)
+
+	// Creating a channel using make() function
+	mychannel1 := make(chan int)
+	fmt.Println("\nValue of the channel1: ", mychannel1)
+	fmt.Printf("Type of the channel1: %T ", mychannel1)
+}
+
+```
+### Output
+
+```bash
+Value of the channel:  
+Type of the channel: chan int 
+Value of the channel1:  0x432080
+Type of the channel1: chan int 
+```
