Use A Conditional To Check Greater Than Number In Swift

Swift’s conditional statements can be very handy when you want to compare values in your program. In this article, we will specifically look at how to use a conditional statement to check if a number is greater than another number in Swift.

Code snippet: Use A Conditional To Check Greater Than Number In Swift

First, let’s take a look at a basic code snippet for this task.

let a = 10
let b = 20

if a > b {
    print("a is greater than b")
} else {
    print("a is not greater than b")
}

In this code, we are checking if the variable ‘a’ is greater than ‘b’. If it is, we print “a is greater than b”. If not, we print “a is not greater than b”.

Code Explanation: Use A Conditional To Check Greater Than Number In Swift

Now, let’s break down the code step by step.

1. Declaration of Variables: We start by declaring two integer variables, ‘a’ and ‘b’, and assigning them values. In this case, ‘a’ is 10 and ‘b’ is 20.

let a = 10
let b = 20

2. If Statement: The if keyword is used to perform a conditional check. We construct a conditional statement using the comparison operator ’>‘. This checks if the variable ‘a’ is greater than ‘b’.

if a > b {

3. Execution based on Condition: If the condition (a > b) evaluates to true, then the statement or block of code within the if statement is executed. In our case, the text “a is greater than b” is printed.

print("a is greater than b")

4. Else clause: The else keyword is used to define a block of code to be executed if the ‘if’ condition is false. In our case, the text “a is not greater than b” is printed.

} else {
    print("a is not greater than b")
}

And that’s all there is to it! By simply using a conditional and a comparison operator, you can efficiently compare numbers in Swift.
