我是靠谱客的博主霸气皮皮虾，最近开发中收集的这篇文章主要介绍在一段内存中查找数据，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

#include <stdio.h>


char code[] = 
            {
            0x64,0x10,0x00,0x00,0x20,0x64,0x00,0x01,0x00,0x80,
            0x01,0x90,0x08,0x07,0x20,0x64,0xa0,0x00,0x03,0x80,
            0x01,0x90,0x08,0x07,0x20,0x64,0x00,0x08,0x00,0x03,
            0x01,0x07,0x20,0x64,0x64,0x00,0x00,0x00,0x03,0x80,
            0x01,0x90,0x08,0x64,0x64,0x00,0x00,0x00,0x03,0x80,
            0x01,0x90,0x08,0x64,0x00,0x00,0x00,0x00,0x00,0x80,
            0x01,0x90,0x64,0x00,0x00,0x00,0x07,0x20,0x03,0x80,
            0x01,0x64,0x00,0x00,0x00,0x20,0x07,0x20,0x64,0xa0,
            0x01,0x90,0x64,0xa0,0x00,0x03,0x80,0x00,0x03,0x80,
            0x01,0x64,0x00,0x01,0x00,0x64,0x01,0x00,0x00,0x80
            };

int main()
{

    int* cp = (int*)code;
    char* cp1 = code;
    for(int i = 0; i < 100; i++)
    {
        if(*cp == 0x64)
        {
            printf("%0xn",&cp[i]);
        }
        cp = (int*)(cp1+i+1);//在最后4个字节的时候，需要判断否则超出的100个字节
        
    }
    return 0;
}
