what is cargo in rust ?, variable and comment. | Rust part 2

 Rust on android part 2 

Today we age going to know about what is cargo and how to generate a rust package using it.

cargo is a package manager in rust , we can check the version of the installed version of cargo using 

"cargo --version" 

To initialize a package using cargo run the command "cargo init  <packagename>"  

then a folder structure is created in current directory, go into that directory. we will see a file called Cargo.toml and a src folder, In src folder main.rs file is created with default "Hello World" program 

to run this run cargo run on your terminal.

Variable declaration in rust 

To declare a variable we use let keyword in rust , variables are immutable in rust by default. To make it mutable  we use mut keyword like this.

let my_name = "Prince Kumar"

let mut my_name = "Prince Kumar"

How to comment in rust ..

To make a comment in rust we use double forward slash (//)  

For multiline comment we use notation like this /* my comment here */
