Print Function

You've been using print() throughout this course to display output. Now let's take a closer look at how this function works and explore some of its useful features.

By default, print() adds a newline character at the end of each output, which is why each print statement appears on its own line:

print("Hello")
print("World")
// Output:
// Hello
// World

You can change this behavior using the terminator parameter. This lets you specify what character (or string) should appear at the end instead of a newline:

print("Hello", terminator: " ")
print("World")
// Output: Hello World

The print() function can also accept multiple items separated by commas. By default, they're joined with spaces:

print("Swift", "is", "fun")
// Output: Swift is fun

You can customize the separator using the separator parameter:

print("2024", "01", "15", separator: "-")
// Output: 2024-01-15
