Comparison Operators

In Rust programming, comparison operators play a vital role in evaluating two values and returning a Boolean result. Let's dive into how these operators work and explore some examples:

1. Comparison Operators: Rust provides a set of comparison operators for evaluating values:

• Equality (==): Compares values on both sides and returns true if they are equivalent.
• Inequality (!=): Returns true if the values on both sides are different.
• Greater Than (>): Evaluates to true if the left operand is greater than the right operand.
• Greater Than or Equal To (>=): Returns true if the left operand is greater than or equal to the right operand.
• Less Than (<): Evaluates to true if the left operand is less than the right operand.
• Less Than or Equal To (<=): Returns true if the left operand is less than or equal to the right operand.

2. Examples:

let a = 1;
let b = 2;

// Comparison operations
let equality = a == b;
let inequality = a != b;
let greater_than = a > b;
let greater_than_or_equal_to = a >= b;
let less_than = a < b;
let less_than_or_equal_to = a <= b;

println!("Equality: {}", equality);
println!("Inequality: {}", inequality);
println!("Greater Than: {}", greater_than);
println!("Greater Than or Equal To: {}", greater_than_or_equal_to);
println!("Less Than: {}", less_than);
println!("Less Than or Equal To: {}", less_than_or_equal_to);

3. Comparison with Different Data Types: Comparison operations can also be applied to data types other than integers. For example, Boolean values can be compared using these operators as well.

4. Restrictions and Considerations: It's essential to note that comparison operators can only be used on similar data types. Attempting to compare values of different data types will result in compilation errors.

let a = 1;
let b = false;

// Comparison operations with Boolean values
let equality = a == b; // Compiler error: Equality operator not implemented for integer and Boolean data types

By understanding comparison operators in Rust, you can effectively compare values and make decisions based on their relationships.
