复制代码 代码如下:

#include <stdio.h>

void memstat(void *memory, size_t memsize) {

printf("-------memory------ ----n");

for(int i=0; i<memsize; i++) {

char *p = (char*) memory;

printf("%d%d%d%d "

, 0x1 & p[i] >> 3

, 0x1 & p[i] >> 2

, 0x1 & p[i] >> 1

, 0x1 & p[i]);

if(i % 4 == 3) {

#define FILTER(c) ((c)<' '? '.': (c))

printf("%c%c%c%c"

, FILTER(p[i-3])

, FILTER(p[i-2])

, FILTER(p[i-1])

, FILTER(p[i]));

puts("");

}

}

printf("------------------- ----n");

}

int main(int argc, char **argv) {

int memory[8];

memset(memory, -1, sizeof(memory));

memory[0] = 3;

memory[2] = 0xAAAAAAAA;

memory[3] = 0;

strcpy((char *)&memory[4], "= = . ");

memstat(memory, sizeof(memory));

}
