What is the mid() method in Euphoria?
Overview
The mid() method is used to slice a sequence source from a start_point to a given length.
Syntax
mid(source,start_point,length)
Parameters
Let’s look at the different parameters used by this function below:
-
source: This is the sequence which will be spliced at the indicated point and to the indicated length. -
start_point: This is an atom value which indicates an index in thesourcewhere the splicing will begin. -
length: This the length which we want the sliced value to have, that is, how much we want thesourceto be spliced. It is an atom value and should be less that or equal to the length of thesourcevariable.
Return value
The mid() method returns a sequence with elements less than or equal to the length parameter.
Example
--include the sequence moduleinclude std/sequence.e--declare some variablessequence source1,source2sequence outcome1, outcome2--assign values to declared variablessource1 = {1,2,3,4,5,6,7}source2 = "This is a good day"--use the mid() methodoutcome1 = mid(source1,2,4)outcome2 = mid(source2,1,8)print(1, {outcome1})printf(1,"\n%s", {outcome2})
Explanation
- Line 2: We include the
sequence.emodule. - Line 5 and 6: We declare some variables.
- Lines 9 and 10: We assign values to the declared variables.
- Lines 14 and 15: We assign the output of using
mid()to theoutput1andoutput2variables. - Lines 17 and 18: We display the outcome.
