char**的C++替代

char **argv;

vector< vector< char > > vvc;

vector< char* > vcp;

vector< char > vc;

string str;

str = "a.out";

vc.assign(str.begin(), str.end());

vc.push_back('\0');

vvc.push_back(vc);

str = "arg1";

vc.assign(str.begin(), str.end());

vc.push_back('\0');

vvc.push_back(vc);

str = "arg2";

vc.assign(str.begin(), str.end());

vc.push_back('\0');

vvc.push_back(vc);

for (int i = 0; i < vvc.size(); ++i)

{

vcp.push_back(&vvc[i][0]);

}

argv = &vcp[0];
