Use a for-in loop to print out a "7 times table". Your output should look like this: 1 * 7 = 7 2 * 7 = 14

Am I doing this right?

for number in 1...10 {Println("(number)times 7 table (number*7)")}

Hi John,

You have a few issues with your code which are as follows:

  1. Your println declaration starts with an uppercase P, it should be lowercase
  2. You're not using interpolation which is required, this is achieved by simply adding a backslash before the parentheses
  3. Your overall string isn't correct, times should have a space before it and be * instead and table should be an equals sign.
for number in 1...10 {
  println("\(number) * 7 = \(number * 7)")

Happy coding!
