How to fix 'struct does not refer to a value' - c++

Question

in my project there are 2 structures, one of which relates to a binary tree, the second to students data
in ' int main ' I can’t access the add function GETDATA
' 'ZKR' does not refer to a value . ' (xcode)
I also can’t create a counter of the number of vertices of my tree
#include <iostream>
#include <ctime>
#include <cstring>
using namespace std;
struct ZKR {
char FACULTY[30];
int ACADEMIC_DEGREE;
char FIO[30];
};
struct point
{
char *data;
point *left;
point *right;
};
point* tree(int n, point* p)
{
point *r;
int nl, nr;
if (n == 0) { p = NULL; return p; }
nl = n / 2;
nr = n - nl - 1;
r = new point;
char s[50];
cout << "Значение: ";
cin >> s;
r->data = new char[strlen(s) + 1];
strcpy(r->data,s);
r->left = tree(nl, r->left);
r->right = tree(nr, r->right);
p = r;
return p;
}
void GETDATA(ZKR*M, int N)
{
cin.ignore();
for (int i = 0; i < N; i++)
{
cout << "\n";
cout << "FACULTY: ";
cin.getline(M[i].FACULTY, 30);
cout << "\n";
cout << "FIO: ";
cin.getline(M[i].FIO, 30);
cout << "\n";
cout << "ACADEMIC DEGREE: ";
cin >> M[i].ACADEMIC_DEGREE;
cin.ignore();
}
}
void treeprint(point *p, int &count) {
if (p != NULL) {
treeprint(p->left, count);
cout << p->data << " ";
treeprint(p->right, count);
if ((p->left == NULL) && (p->right == NULL))
count = count + 1;
}
}
int main()
{
setlocale(LC_ALL, "russian");
srand(time(NULL));
int n = 0, k = 0, count = 0;
point *beg = nullptr;
cout << "Enter the number of students" << endl;
int N;
cin >> N;
ZKR*M = new ZKR[N];
do
{
cout << "1. BUILD a binary tree\n";
cout << "2. SHOW a binary tree\n";
cout << "3. GETDATA\n";
cin >> k;
switch (k)
{
case 1:
cout << "Введите количество элементов" << endl;
cin >> n;
beg = tree(n, beg);
cout << endl;
break;
case 2:
treeprint(beg, count);
cout << endl;
cout << "Листьев в дереве: " << count << endl;
break;
case 3:
GETDATA(ZKR*M, N);
break;
}
} while (k != 4);
system("pause");
return 0;
}
I will be grateful for any help

Answer 1

This line is not syntactically correct:
GETDATA(ZKR*M, N);
Replace it with:
GETDATA(M, N);
M is a pointer to an object of type ZKR.
