I'm using codeblocks IDE and I don't know what is the problem.
I tried making the variables global but it still doesn't work.
The problem is in the function name. Calculate_area has a capital 'C' in its function declaration name, but not in the prototype declaration.
Change your function declaration at line 31 with:
unsigned long calculate_area(unsigned long side);

Query:
DECLARE #Patd_base nvarchar(50) = 'axx';
PRINT #Patd_base
Output is
?axx
Why is the ? in the output? What does it mean?
Thanks for the help!
I believe you copied and pasted the value 'axx' from elsewhere. It has a hidden extended character in it.
When I copy/pasted your command above into Notepad++, and converted to ANSI encoding, I got '‪axx'

I have the following problem: I have to build a DLL with some Header-Files from a supplier. There are some typedefs in those headerfiles which store WINAPI-Functionpointers.
Example:
typedef struct {
int(WINAPI *myFunc)(int, int);
}
However, VS2015 always underlines the star ("*") saying it expected an ")".
I cant change the functions stored in those pointers so I have to fix this.
Anyone knows a solution for this?
Since the WINAPI-Macro is defined in Windows.h, I just forgot to include it.
Result: Including the -Header seems to fix this problem.

Given the following function:
image_ret* minify_1(image_src img_src, CLIENT* cl) {
image_ret* img_ret;
magickminify_init();
magickminify(img_src.image_src_val, img_src.image_src_len, (ssize_t*)&img_ret->image_ret_len);
return image_ret;
}
The compiler is telling me "expected expression before ‘image_ret’" with regard to the last line. I'm sure I'm missing some fundamental aspect of syntax here, but I don't know what. Lil' help?
You need to return a value, not a type. image_ret is a type, img_ret is a poitner to a value of that type and probably what you want to return, except I see nowhere in your code where you allocate any storage to it, or initialising any of the fields except image_ret_len

I am getting this warning with below piece of initialization code.
const uint16_t macaddr_reg[] = {0x2006, 0x2007, 0x2008, 0x2009, 0x2000A, 0x200B };
However below code gives no warning
const uint16_t tmp = 0x2006;
Please let me know where am I wrong? I am using gcc compiler.
It was a typo mistake. Corrected it.
Notice 0x2000A in initialization. It is not 16 bit.

# define a 10
main()
{
#define a 50
printf("%d",a);
}
The output is coming 50. Why is it happening so? Shouldn't the output come 10?
Compilation happens from top to bottom. so value of a is replaced by 50 when it enters into main function.
Here the local has precedence than global
