What is the output of "4"+5+7+"8"

Thanks to all for helping me

dont be confused Akash....
if you want addition of 5 and 6 to attach string then use below.......

"4" + ( 5 + 6) + "10"

Hi Akash,


string str = "4" + 5 + 7 + "8";
output is : 4578


Thanks.

Still I am confused about the final result?

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.
                                 

Hi,
   

Operator Precedence 

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

Why it is not  4128?(add 5 and 7)

Hi Akash,

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


Thanks,
