Rust program to demonstrate the isize and usize datatypes

Program/Source Code:

The source code to demonstrate isize and usize datatype is given below. The given program is compiled and executed successfully.

// Rust program to demonstrate 
// isize and usize datatypes.

fn main() {
	// The pointer-sized signed integer type
	let mut var1:isize=-10;  
	// The pointer-sized unsigned integer type
	let mut var2:usize=30;  

	println!("Var1: {}",var1);
	println!("Var2: {}",var2);
}

Output:

Var1: -10
Var2: 30

Explanation:

Here, we created 2 variables var1, var2 of isize and usize datatype respectively. Then we printed the value of variables using println!() macro.
