              已知類String 的原型為:

            未來的學校想象作文(精選34篇)

              class String

              {

              public:

              String(const char *str = NULL); /pic/p>

              String(const String &other); /pic/p>

              ~ String(void); /pic/p>

              String & operate =(const String &other); /pic/p>

              private:

              char *m_data; /pic/p>

              };

              請編寫String 的上述4 個函數。

              標準答案:

              /pic/p>

              String::~String(void) /pic/p>

              {

              delete [] m_data;

              /pic/p>

              }

              /pic/p>

              String::String(const char *str) /pic/p>

              {

              if(str==NULL)

              {

              m_data = new char[1]; /pic/p>

              *m_data = ‘\0’;

              }

              else

              {

              int length = strlen(str);

              m_data = new char[length+1]; /pic/p>

              strcpy(m_data, str);

              }

              }

              /pic/p>

              String::String(const String &other) /pic/p>

              {

              int length = strlen(other.m_data);

              m_data = new char[length+1]; /pic/p>

              strcpy(m_data, other.m_data);

              }

              /pic/p>

              String & String::operate =(const String &other) /pic/p>

              {

              /pic/pic/p>

              if(this == &other)

              return *this;

              /pic/pic/p>

              delete [] m_data;

              /pic/pic/p>

              int length = strlen(other.m_data);

              m_data = new char[length+1]; /pic/p>

              strcpy(m_data, other.m_data);

              /pic/pic/p>

              return *this;

              }
