Here are the steps on how to print constants and variables in Swift:
- Declare a constant or variable.
- Use the print() function to print the value of the constant or variable.
- Optionally, specify a separator and terminator for the output.
Here is an example of how to print a constant:
let myConstant = 10
print(myConstant)
This will print the value of myConstant, which is 10, to the console.
You can also specify a separator and terminator for the output. The separator is a string that is inserted between each value that is printed. The terminator is a string that is inserted at the end of the output.
Here is an example of how to specify a separator and terminator:
let myConstant = 10
let myOtherConstant = 20
print("The value of myConstant is (myConstant), and the value of myOtherConstant is (myOtherConstant)")
This will print the following to the console:
The value of myConstant is 10, and the value of myOtherConstant is 20
The separator is a comma, and the terminator is a newline character.
You can also use string interpolation to print the value of a constant or variable. String interpolation allows you to insert the value of a constant or variable into a string.
Here is an example of how to use string interpolation:
let myConstant = 10
print("The value of myConstant is \(myConstant)")
This will print the following to the console:
The value of myConstant is 10
The value of myConstant is inserted into the string at the placeholder \(myConstant).
