As for what the error means: 2(x&y) tells the compiler to call the function 2, passing x&y as an argument (just like printf(“hi”) means “call printf and pass “hi” as an argument“). But 2 isn’t a function, so you get a type error. Syntactically speaking, whenever you have a value followed by (, that’s a function call.
The problem is that you’re freeing the sym, then trying to access a value from the (now-freed) data: sym->next. You probably want something like this for the inner loop:
I am trying to write a program which implements the Pop and Push functions. The problem is, I am trying to pass the pointer that points to integer Top to the function, so that this integer keeps changing, but when I try to compile I always get this line: **error: called object is not a … Read more
You need to link with the math library: The error you are seeing: error: ld returned 1 exit status is from the linker ld (part of gcc that combines the object files) because it is unable to find where the function pow is defined. Including math.h brings in the declaration of the various functions and not their definition. The def is present in … Read more
When you link the program you need to give both Main.o and Person.o as inputs. Build usually is done in two steps (1) compilation and (2) linking. To compile your sources do: Or in one line: Then the resulting object files must be linked into a single executable: For small projects, of a few compilation … Read more

You cannot do a conditional branch without first setting the condition register somehow. This can be done with cmp or by adding s to most instructions. Check out the ARM assembly documentation for details. Quick example: Branch if r0 greater than 5: Compare r6 with r4 , put difference into r7, branch if r7 < 0:
Simply put, a ” No route to host”” would mean that there is no route for the server IP address in the client’s routing table. Are you able to ping the server’s IP address? Most likely you should not be able to and ping should say that the server is not reachable. If so, then … Read more
