while debugging i got error like Lvalue Required....
plse suggest a solution..

What language is this?

Please make sure you are using code tags when you are posting your code. And I think you are going to need to provide more information if we are going to try and help you.

You need to read our Posting Guidellines

Its C or C++ something like that.

   char temp_string[80];
   ...
	temp_string[80]=z;

*boing* that's an OBOE (Off By One Error)

kind regards,

while debugging i got error like Lvalue Required....

When *compiling*. When you press debug, it compiles and links first and then debug.

plse suggest a solution..

Identify location ( by line number mentioned in error message). Identify left part of the assignment. Fin wy it can't be there.

 char *temp[10];
    int i;
    for(i = 0;i != 16;i++)
        temp[15-i] =

'Off by 6' error.
... And you should not return pointers to local variable in this way.
