string s =“abc”;

constchar* c_s = s.c_str();

const char转string

直接赋值即可

constcharc_s =“abc”;

string s(c_s);

string转char*

string s =“abc”;

char* c;

constint len = s.length();

c =newchar[len+1];

strcpy(c,s.c_str());

char转string

charc =“abc”;

string s©;

const char转char

constchar* cpc =“abc”;

char* pc =newchar[100];//足够长

strcpy(pc,cpc);
