list.remove()函数删除结构体结点

Posted on Edited on In Views:

使用stl中list的list.remove()函数删除结构体结点时，会遇到==的运算符重载问题，解决方法如下：

  • 结构体定义内容：
1
2
3
4
5
6
struct msg
{
  string studentNumber;
  string studentName;
  int gradeChinese, gradeMath, gradeEnglish;
}
  • ==运算符重载实现
1
2
3
4
5
6
7
8
9
10
bool operator ==(const CInfoFile::msg& msg1, const CInfoFile::msg& msg2)
{
  bool flag = false;
  if (msg1.studentNumber == msg2.studentNumber 					              		  &&msg1.studentName==msg2.studentName
	  &&msg1.gradeChinese==msg2.gradeChinese
      &&msg1.gradeEnglish==msg2.gradeEnglish
      &&msg1.gradeMath==msg2.gradeMath)
  flag = true;
  return flag;
}
