# find the remainder of two numbers in swift

To find the remainder of two numbers in Swift, you can use the modulo operator, represented by the percent symbol (%). The modulo operator returns the remainder of the division of two numbers.

Here's an example code snippet:

```main.swift```let a = 10
let b = 3
let remainder = a % b

print(remainder) // Prints 1
```73 chars6 lines```

In this example, we declare two constants, `a` and `b`, and initialize them with the values 10 and 3, respectively. We then calculate the remainder of `a` divided by `b` using the modulo operator, and assign the result to a new constant called `remainder`. Finally, we print the value of `remainder` to the console, which should be 1.

You can also use the shorthand compound assignment operator `%=` to calculate the remainder and assign it to a variable or constant in one step, like this:

```main.swift```var x = 15
let y = 4
x %= y

print(x) // Prints 3
```50 chars6 lines```

In this example, we declare a variable `x` with the initial value of 15 and a constant `y` with the value of 4. We then use the `%=` operator to calculate the remainder of `x` divided by `y`, which is 3, and assign the result back to `x`. The final value of `x` is printed to the console.
