字符数组中的null是否会阻止内存被删除？

Question

有内存泄漏吗？

    const char * pname = "NAME";
    char * temp = new char[strlen(Name) + 64];
    sprintf(temp,"%s", pname);

    delete [] temp; // is there any memory leaks because now length of temp is 4.

Answer 1

删除(修改)字符串文字(pname)是未定义的行为.此外new/delete,new []/delete[]仅用于配对.

std::string如果可以,建议使用,让你std::string管理内存分配/释放.

  std::string pname("NAME");
  std::string temp(pname);
  std::cout << pname << std::endl;
