Rust program to create different types of variables

Program/Source Code:

The source code to create different types of variables is given below. The given program is compiled and executed successfully.

// Rust program to create 
// different types of variables

fn main() {
    let var1:i8     =10;        //8-bit signed integer 
    let var2:u16    =20;        //16-bit unsigned integer 
    let var3:f32    =30.12;     //32-bit floating point number
    let var4:bool   =true;      //Boolean value
    let var5:char   ='A';       //Character
    
    println!("Var1: {}",var1);
    println!("var2: {}",var2);
    println!("var3: {}",var3);
    println!("Var4: {}",var4);
    println!("Var5: {}",var5);
}

Output:

Var1: 10
var2: 20
var3: 30.12
Var4: true
Var5: A

Explanation:

In the main() function, we created 5 different types of variables using the let keyword. Then we printed the value of variables using println!() macro on the console screen.
