What happens if we want multiple integers to be printed in a statement? How would the syntax be different?

Supposing I have

int days_in_a_week = 7; int hours_in_a_day = 24;

How can I express both these int using %d?

Thanks :)

In swift, you just simply add () outside the variable or constant you want to display. So it should look similar to

// Swift
var mInt = 18
var mAnotherInt = 19
print("First one is\(mInt). The second one is \(mAnotherInt)")

In objective C, it is kind of different, instead, you add %d in the string where you want to display your data, and the second %d will require you to add a second argument. So it will look like

Int mInt = 18;
Int mSecondInt = 19;
NSLog(@"The first one is %d, and the second one is %d", mInt, mSecondInt);

Hi there, I guess you want to display both days_in_a_week and hours_in_a_day using the same output statement. Well if that is the case, it can be done as:

printf("There are %d days in a week and %d hours in a day",days_in_a_week,hours_in_a_day);

Hope this helps :)
