Because I am getting error like this:
main.c:6:3: error: initializer element is not constant
What I have tried:
#include
<
stdio.h
>
#include
<
stdlib.h
>
struct
Node{
int
a;
int
b;
a=(
struct
Node*)malloc(
sizeof
(
struct
Node));
int
main()
printf(
"
Hello world"
);
return
0
;
It's not inside a function, which means it has to be an initializer - which is assigned only when the item is declared - which means it must be a constant value at compile time, which malloc cannot be.
Move the line inside the main function and it'll work:
#include
<
stdio.h
>
#include
<
stdlib.h
>
struct
Node{
int
a;
int
b;
int
main()
a=(
struct
Node*)malloc(
sizeof
(
struct
Node));
printf(
"
Hello world"
);
return
0
;
Read the question carefully.
Understand that English isn't everyone's first language so be lenient of bad
spelling and grammar.
If a question is poorly phrased then either ask for clarification, ignore it, or
edit the question
and fix the problem. Insults are not welcome.
Don't tell someone to read the manual. Chances are they have and don't get it.
Provide an answer or move on to the next question.
