宏变量的打印

#define MACRO "aaa" 
#define M 12
#include<stdio.h>;


void main()
{
        printf(" %s\n ", MACRO);
printf(" %d\n ", M);

}

//宏可以复制给变量
#define MACRO "aaa" 
#define M 12
#include<stdio.h>;


void main()
{
int y;
y=M;
        printf(" %s\n ", MACRO);
printf(" %d\n ", M);
printf(" %d\n ", y);
}
