Here, we are going to learn how to print the binary number of a given decimal number in Rust programming language?
Submitted by Nidhi, on September 24, 2021

Problem Solution:

Here, we will create an 8-bit integer number and then we will print the corresponding binary number using format specifier in println!() macro.

Program/Source Code:

The source code to print the binary number of a given decimal number is given below. The given program is compiled and executed successfully.

```// Rust program to print the binary number
// of a given decimal number

fn main()
{
let num:i8 = 14;

println!("Binary number is: {:#02b}", num);
}
```

Output:

```Binary number is: 0b1110
```

Explanation:

Here, we created an 8-bit integer variable num with an initial value of 14. Then we printed the corresponding binary number using the ":#02b" format specifier in println!() macro.
