Strings

In this task we're going to declare two strings. First, declare a constant named name and assign to it a String containing your name.

Second, declare a constant named greeting. Set the value of greeting to an interpolated string that combines "Hi there, " with the string stored in the name constant.

strings.swift 
// Enter your code below
let name = "Abotsi"

For the first part it asks to create an interpolated string of your name and greeting. You already wrote the constant with your name. Now you have to declare a constant named greeting that combines a string with the name constant you created. To do this in the “ “ you use this syntax ( ). It would end up looking like this

let example = “example” 
let stringInterpolation = “This is my \(example)”

I’m using ( ) around the name of the constant example I created with a string value. For this example the code would look like this.

let name = "Elliot Alderson"
let greeting = "Hi there, \(name)"

The second part wants you to concate two string values and assign it to constant finalGreeting. To concatenate two strings you use an assignment operator ( + ). It would be like this.

 let example = "example"
let stringConcatenation = example + "of how you concatenate strings"

I declare the constant stringConcatentation and this time instead of using brackets and a back slash. I just type the name of the constant in this case example afterwords put the assignment operator then the new string I want to concatenate with. Hope this helps !

The first part wants you to use string interpolation to assign the name constant as part of the string in the greeting constant. That way it reads "Hi there, "Elliot Alderson" 

let name = "Elliot Alderson"
let greeting = "Hi there, \(name)"

this second part it wants string concatenation. The way this is set up is using the name of the constant then the assignment operator + and then writing out the new string. If you write the constant finalGreeting with string interpolation it won't accept your answer even if it prints the correct phrase. 

let name = "Elliot Alderson"
let greeting = "Hi there, \(name)"

let finalGreeting = greeting +  ". How are you ?"

I put the period and then added a space before typing out How so that way it matches the string it wanted. Hope this helps!
