Rust Conditional Statements

\\n

In Rust language, conditional statements follow this format:

\\n

Example

\\n

fn main(){

\\n

let number =3;

\\n

if number <5{

\\n

println!("Condition is true");

\\n

}else{

\\n

println!("Condition is false");

\\n

}

\\n

}

\\n

In the above program, there is a conditional if statement. This syntax is common in many other languages, but there are some differences: First, the conditional expression number < 5 does not need to be enclosed in parentheses (note: not needed doesn't mean prohibited); However, in Rust, there is no rule that single statements don't need {}, and using a single statement to replace a block is not allowed. Nevertheless, Rust still supports the traditional else-if syntax:

Example

\\n

fn main(){

\\n

let a
