#include <stdio.h>
#include <string.h>
struct{int x,y;}x;
struct{int x,y;}y;
int main(void)
{
return 0;
}
Are theses declararations legal on an individual basis these structs? Could both declarations appear as shown in the code or program?
Wen a structures is declared, it represents a new scope. Therefore, each structure has it own name space. So, nothing wrong with the above snippet.

I am working on one embedded project based on c language.
Can you explain me following declaration meaning:
#define FILE_APPVENDORPARAM APP_NAME"VENDOR"
Before the line you show, there must be another #define that defines APP_NAME, for example like this:
#define APP_NAME "SomeName"
Then this line:
#define FILE_APPVENDORPARAM APP_NAME"VENDOR"
defines FILE_APPVENDORPARAM as "SomeName""VENDOR" which is the same thing as "SomeNameVENDOR"

I getting code 0 error while compiling very simple code. How do I solve it?
I using VS 2017 for the first time.
#include <stdio.h>
void main()
{
printf("My name is Haim");
}
The two rows in the middle are not supposed to be there!
Haim
Your main() should return some exit code. So int should be as the return type.
In the other hand exit code 0 means, that everything was succesfull, see.

Presuming I have a program in C:
#include<stdio.h>
#include<time.h>
int main()
{
int a = rand() % 1000;
return 0;
}
How can I find the value of "a" without printing it on the console, but by accessing, with a linux terminal command, its address to read the value from it?
Or generally, how can I map all the written values of a binary without seeing its implementation (like a "blackbox")?
Memory is accessible via /proc/pid/mem, index is /proc/pid/maps, Python prototype is how-do-i-read-from-proc-pid-mem-under-linux.

could anyone explain me please what does this piece of code mean?
int **d= (int**)malloc((m+1)*sizeof(int));
What are those ** for the d and the (int) ? Are they someway related to pointers?
int** d; //pointer to a pointer to an integer

I'd love to create some part dynamically. Would it be possible to use offsetof with string as a second argument? Something like:
offsetof( tic, "close.v");
Or can I convert char to member anyhow?
The offsetof construct is a compile time operation. It can't be used with anything that is generated dynamically.
