Datta Kharad · Answer

Hi string str = "4" + (5 + 7) + "8"; In above expression, number 4 represent as string bcoz double quotes on 4, it is print as 4. operator + is used for concatination where two operands are (string and int, string and string) and addition where two operands are (int and int), operator precedence first preference to parenthesis then first it will add 5 and 7 =12 and 8 is string it only concatinated to 12. string str = "4" + (5 + 7) + "8"; Result :- 4+(5+7)+8 4+12+8 4128. string str2 = "4" + 5 + 7 + "8"; Result:- 4578.

Tulasi · Answer

Hi, Operator Precedence is also one reason for this Response.Write("4" + (5 + 7) + "8"); // 4128

Akash Ahlawat · Answer

Why it is not 4128?(add 5 and 7)

Pravin More · Answer

Hi Akash, output will be 4578. becoz "4" and "8" are strings, so 5 and 7 gets attached to it by "+" operator. Thanks, Pravin.
