程序代码：

#include <stdio.h>

#define DEBUG_A 0
#define DEBUG_B 1
#define DEBUG_C 2
#define DEBUG_D 3

int main(int argc, char* argv[])
{
    int a[]={DEBUG_A,DEBUG_B,DEBUG_C,DEBUG_D};
    char* b[]={"DEBUG_A","DEBUG_B","DEBUG_C","DEBUG_D"};
    int i;
    for(i=0;i<4;i++)
    {
        if(i==a[i]) printf("%s\n",b[i]);
    }
    return 0;
}
