char*，const char*，string的相互转换C++

string转const char* string s =“abc”; constchar* c_s = s.c_str();

const char转string 直接赋值即可 constchar c_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 char c =“abc”; string s©;

const char转char constchar* cpc =“abc”; char* pc =newchar[100];//足够长 strcpy(pc,cpc);
