返回字符串

举个简单的例子.

#include <iostream>#include <malloc.h>using namespace std;char* get_str(){char *buffer = new char[20];memset(buffer, 0, _msize(buffer));strcpy(buffer, "hello world!");return buffer;}int main(int argc, char** argv){char *ptr = get_str();cout << ptr << endl;delete ptr;ptr = NULL;return 0;}
