如何将16进制文本转化成2进制数字

怎么将16进制文本转化成2进制数字？
若我读到的内容是16进制：605914F05A5B267308CA0FF01D0DF120C321F588CA0274F1B2B31EB508CA004C8C，
怎么转化成2进制数字？


[解决办法]

C/C++ code

#include<stdio.h>const char *HEX[16]= {"0000","0001","0010","0011",                      "0100","0101","0110","0111",                      "1000","1001","1010","0011",                      "0100","1101","1110","1111",                     };int main(){    const char *str="605914F05A5B267308CA0FF01D0DF120C321F588CA0274F1B2B31EB508CA004C8C";    int n=0;    const char *p=str;    while(*p)    {        sscanf(p,"%1X",&n);        puts(HEX[n]);        p++;    }    return 0;}

引用:

C/C++ code

#include<stdio.h>
const char *HEX[16]= {"0000","0001","0010","0011",
"0100","0101","0110","0111",
"1000","1001","1010","0011",
……
可是怎样将转化的值赋给一个量呢？如，data=0110000001011……

       string data = filename;
       string getdata = data.substr(4, 100);
       string dddd = transferData(getdata);
       cout << dddd;
