RUST Operators

RUST operators commonly used can be defined as 3 categories:

Arithmetic
Relational
Logical

Arithmetic Operators

Operator	Description
+ (Addition)	returns the sum of the operands
- (Substraction)	returns the difference of the values
* (Multiplication)	returns the product of the values
/ (Division)	performs division operation and returns the quotient
% (Modulo)	performs division operation and returns the remainder

RUST Example of Arithmetic Operators

fn main() {
 let num1 = 10 ;
 let num2 = 2;
 let mut result:i32;
 result = num1 + num2;
 println!("Sum: {} ",result);
 result = num1 - num2;
 println!("Difference: {} ",result) ;
 result = num1*num2 ;
 println!("Product: {} ",result) ;
 result = num1/num2 ;
 println!("Quotient: {} ",result);
 result = num1%num2 ;
 println!("Remainder: {} ",result);
}

Output

Sum: 12
Difference: 8
Product: 20
Quotient: 5
Remainder: 0

Relational Operators

Operator	Description
>	Greater than
<	Lesser than
>=	Greater than or equal to
<=	Lesser than or equal to
==	is Equal
!=	is not Equal

RUST Example of Relational Operators

fn main() {
	let A:i32 = 10;
	let B:i32 = 20;
	println!("Value of A:{} ",A);
	println!("Value of B : {} ",B);
	let mut res = A>B ;
	println!("A greater than B: {} ",res);
	res = A<B ;
	println!("A lesser than B: {} ",res) ;
	res = A>=B ;
	println!("A greater than or equal to B: {} ",res);
	res = A<=B;
	println!("A lesser than or equal to B: {}",res) ;
	res = A==B ;
	println!("A is equal to B: {}",res) ;
	res = A!=B ;
	println!("A is not equal to B: {} ",res);
}

Output

Value of A:10
Value of B : 20
A greater than B: false
A lesser than B: true
A greater than or equal to B: false
A lesser than or equal to B: true
A is equal to B: false
A is not equal to B: true

Logical Operators

Operator	Description
&& (And)	The operator returns true only if all the expressions specified return true
\|\|(OR)	The operator returns true if at least one of the expressions specified return true
! (NOT)	The operator returns the inverse of the expression’s result. For E.g.: !(>5) returns false

RUST Example of Logical Operators

fn main() {
	let a=20;
	let b=30;
	if (a > 10) && (b > 10) {
	 println!("true");
	}
	let c=0;
	let d=30;
	if (c>10) || (d>10){
	 println!("true");
	}
	let is_elder=false;
	if !is_elder {
	 println!("Not Elder");
	}
}

Output

true
true
Not Elder
