puts(1,"What is ") print(1,first_number) puts(1," + ") print(1,second_number) puts(1,"?")
First_number and second_number are variables for two integers. Thanks.
Edit: Added <eucode> tags. -Greg

puts(1,"What is ") print(1,first_number) puts(1," + ") print(1,second_number) puts(1,"?") First_number and second_number are variables for two integers. Thanks.
printf(1, "What is %d + %d?", {first_number,second_number} )
See printf for more details.

-- Version 4 Code writef("What is [] + []?", {first_number, second_number})

I have a habit of doing this:
puts(1, "What is " & sprint(first_number) & " + " & sprint(second_number) & "?")

writef("What is [] + []?", {first_number, second_number})
Derek, when would one use printf() vs. writef()? Is printf() going to be phased out or does it still have its place?

Good question. printf is not going to go away as far as I can see. The choice as to which one to use will depend on your requirements.
The advantages of writef are...
- simpler tags. You don't need %s, %d, %f etc just [] for all data types.
- you can specify the order of the arguments in the tags.
- writef("[2] follows [1]", {"day, night"}) comes out as "night follows day".
- There are more output options than printf, eg. binary, octal and hex numbers.
- The tag syntax is a little more forgiving about how you code it.
The advantage of printf, for now any way, is that it is faster as it is a built-in routine and not a library routine.
We use writef internally in Euphoria for error messages because we need to specify the word order to cater for other languages when messages are translated.
