Questions such as items, want to watch to create and query
Want to ask next how change to achieve
The code is as follows:

using namespace std;
The class table_item
{
int num;
Int a, [8].
Public:
Table_item ()

}
Table_item (int n, int * p)
{

Num=n;
For (int I=0; I & lt; 8; I++ p++)
A [I]=* p;
}
Table_item (table_item & amp; Y)
{

Num=y.n um.
Memcpy (a, y.a, 32);
}

Void the display ()
{
Cout & lt; <"Num:" & lt; For (int I=0; I & lt; 8; I++)
Cout & lt; Cout & lt; <"\ n";
}

};

Int main ()
{
MapCout & lt; <"Please type you want to enter the number of" & lt; int n; Cin & gt;> n;
int i;

Namelist [x]=sample;
}

Bool samename (string x, iterator it)
{
Return it - & gt; The first==x;
}

CodePudding user response:

Other place also is a little small fault, correct

CodePudding user response:

You can define an iterator it it - & gt; Second, the display

CodePudding user response:

MapIter - & gt; Second, the display ();
