write "5apples" + "7 orange" //Ans :12
Values are string , why add numeric value . its an error or correct . please tell me.
because + is an operation for numbers, and yes, answer is correct, because 5 + 7 is 12
if you expected to see "5apples7 orange", in this case you should use concatenate operator "_"
write "5apples" _ "7 orange"
AFAIK everything is a string, it's just parsed prior to being processed. So it sees the 5, then characters it omits, same for the other string, so you are left with two numbers (which probably are processed as floats) which the + operator adds. Is that correct?
Numeric operators convert their arguments to numbers (according to well defined rules) before performing the operation. That's why "5apples"+ "7 orange" gives 12.
Conversely, string operators convert their arguments to strings before the operations is performed.
In other words, regardless of the arguments, the operator automatically performs the necessary conversions according to what it expects.
Hi, Ponnumani. I've changed the title to closer to the question version.
Thank you for your guidance . But "" its mentioned string . how to add a string ?
if you need add a string, you should concatenate it with operator _
+ converts all types to number, and doing arithmetical operator add
7_"" became "7"
+"5apples" became 5
Thank you Dmitry
