如何在C中连接两个字符串宏？

#include <stdio.h>

#define STRING_A "Hello"
#define STRING_B "World"

int main() {
    printf("%s %s\n", STRING_A, STRING_B);
    return 0;
}

#include <stdio.h>

#define STRING_A "Hello"
#define STRING_B "World"
#define CONCATENATED_STRING STRING_A " " STRING_B

int main() {
    printf("%s\n", CONCATENATED_STRING);
    return 0;
}
