C - arrays, getting errors (very simple code)

[dazzler]

Please tell me why I get errors while compiling my code with GCC =(

#include <stdio.h>
 
int a[3];
a[0] = 12;
a[1] = 9;
a[2] = 14;
 
int main(){
   printf("%d",a[0]);
}
 

Errors what I get:
test_code.c:4: error: conflicting types for 'a'
test_code.c:3: error: previous declaration of 'a'
test_code.c:4: warning: data definition has no type or storage class
test_code.c:5: error: conflicting types for 'a'
test_code.c:4: error: previous declaration of 'a'
test_code.c:5: warning: data definition has no type or storage class
test_code.c:6: error: conflicting types for 'a'
test_code.c:5: error: previous declaration of 'a'
test_code.c:6: warning: data definition has no type or storage class

There are some errors in the code like
1) you have to use "using namespace std;" after including header files according to new conventions.

2) return 0 in main()

3) write declaration of a in main() function

You can't initialize an array like that; those are three statements and statements
are not allowed outside function bodies; that's why the compiler whines at you.

Either move those three statements to the body of your main() function or initialize
that array as follows:

int a[] = { 12, 9, 14 };
 

kind regards,

Jos
