Rust program to convert a decimal number to a binary number

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

Problem Solution:

Here, we will create a 16-bit integer number and then print the corresponding binary number.

Program/Source Code:

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

// Rust program to convert decimal number 
// to binary number

fn main() {
    let mut num:i16 = 14;
    let mut cnt:i16 = 15;
    let mut tmp:i16 = 0;
    
    println!("Decimal Number: {}",num);
    print!("Binary Number: ");
    while cnt>=0
    {
        tmp = num & (1<<cnt);
        if tmp>0
        {
            print!("1");
        }
        else
        {
            print!("0");
        }
        cnt = cnt - 1;
    }
}

Output:

Decimal Number: 14
Binary Number: 0000000000001110

Explanation:

Here, we created an integer variable num with an initial value of 14. Then we used bitwise operators to print the corresponding binary number.
