Code not compiling?

Question

C++ / C#

An error occurs while compiling this code.

#include <stdio.h>

struct {
        int debug;
} config;
config.debug=1;

int main() {
        printf("%d",config.debug);
        return 0;
}

The error is like this

ain.c:6:1: error: unknown type name 'config'
config.debug=1;
^
main.c:6:7: error: expected identifier or '('
config.debug=1;
      ^
2 errors generated.

Answer 1

Your assignment operation lies outside the function. The compiler waits there for declarations of variables, functions, types, that's all, and you have an operation there. Move the assignment to main().
If you want to initialize a structure, you can use an initialization list:

struct {
        int debug;
} config = {1};
