一、字符转化成二进制
#include <iostream>#include <bitset>using namespace std;int main(){//字符转化成二进制串bitset<8> bits = bitset<8>('a');bitset<1> tmp;//二进制翻转for(int i=0;i<4;i++){tmp[0] = bits[i];bits[i] = bits[7-i];bits[7-i] = tmp[0];}//输出for(int i=0;i<8;i++)cout<<bits[i];}
二、字符串转化成二进制字符串
#include <iostream>#include <bitset>#include <string>#include <algorithm>using namespace std;//将8位字符串转化为64bitstring StrToBitStr(string str){bitset<64> bstr ;for(int i=0;i<8;i++){bitset<8> bits = bitset<8>(str[i]);cout<<str[i]<<endl;for(int j = 0;j<8;j++){bstr[i*8+j] = bits[7-j];}}string s = bstr.to_string();//添加一个翻转操作reverse(begin(s),end(s));return s;}int main(){string bstr = StrToBitStr("generate");cout<<bstr<<endl;}
三、二进制字符串转化成字符串
#include <iostream>#include <bitset>#include <string>#include <algorithm>using namespace std;//将8位字符串转化为64bitstring StrToBitStr(string str){bitset<64> bstr ;for(int i=0;i<8;i++){bitset<8> bits = bitset<8>(str[i]);cout<<str[i]<<endl;for(int j = 0;j<8;j++){bstr[i*8+j] = bits[7-j];}}string s = bstr.to_string();//添加一个翻转操作reverse(begin(s),end(s));return s;}//将64bit二进制字符串转化为字符串string BitStrToStr(string bstr){string str="";//每八位转化成十进制，然后将数字结果转化成字符int sum;for(int i=0;i<bstr.size();i+=8){sum=0;for(int j=0;j<8;j++)if(bstr[i+j] == '1')sum = sum*2+1;elsesum = sum*2;str =str+char(sum);}return str;}int main(){string bstr = StrToBitStr("generate");cout<<bstr<<endl;cout<<BitStrToStr(bstr)<<endl;}
