"Bezieht sich nicht auf Wert" Fehler in C++ prozedurale

Question

Alle meine Fehler sind genau das gleiche und ich kann nicht herausfinden, warum. Jeder Rat wäre hilfreich. Ich muss prozedurales C++ verwenden.

#include <stdio.h> 

typedef struct Elem { 
    float Element; 
}ELEM; 

typedef struct Vector { 
    unsigned int size = 0; 
    Elem *numbers[]; 
}VECTOR; 

// print_vec: 
// prints the vector array if it isn't NULL 
// in: 
// RefToVector - single dimensional array of Elem's 
// Out: 
// Returns true if the array isn't NULL and it has something to print, NULL if otherwise 
bool print_vec(Vector *numbers) { 
    if (numbers != NULL) { 
     printf("%f", numbers); 
     return true; 
    } 
    else { 
     return NULL; 
    } 
} 

// *alloc_vec 
// Allocates an empty vector array 
// In: 
// Nothing 
// Out: 
// A newly allocated vector array 

Vector *alloc_vec() { 
    Vector *numbers = new Vector; 
return numbers; 
} 

// dealloc_vec 
// deallocates array 
// In: 
// an allocated array 
// out: 
// Return: True if successfull, NULL if not 

void dealloc_vec(Vector *numbers) { 
    delete Vector *numbers; 
} 

// extend_vec 
// Extends the vector by one element in size 
// In: 
// Vector array of x elements 
// Out: 
// Vector array of x + 1 elements 
// Return: 
// A pointer to the new vector 

Vector *extend_vec(Vector *numbers, Elem) { 
    Vector *bigger = alloc_vec(); 
    bigger->size = numbers->size + 1; // set the size of the new vector to the size of the old plus one more element 
    for (int i = 0; i <= numbers->size; i++) { 
     bigger[i] = numbers[i]; // step through the vectors and copy the values 
    } 
    bigger[bigger->size-1] = Elem; // set last place in the new vector to the new element 
    return bigger; 
} 


// scalar_plus 
// Steps through the vector elements' and adds the same value to all of them 
// In: 
// Reference to a vector(array) 
// Out: 
// Return: reference to vector with Elem value added to each 

Vector *scalar_plus(Vector *numbers, Elem) { 
    for (unsigned int i = 0; i <= numbers->size; i++){ 
     numbers[i] = numbers[i] + Elem; 
    } 
    return numbers; 
} 

Meine Fehler sind alle gleich. und hier sind sie

    delete Vector *numbers;

typedef struct Vector { 
      ^
vecalc.cc:99:11: error: 'Vector' does not refer to a value 
       assert(&Vector == NULL) 
         ^
vecalc.cc:8:16: note: declared here 
typedef struct Vector { 
      ^
vecalc.cc:103:14: error: 'Vector' does not refer to a value 
       print_vec(*Vector); 
         ^
vecalc.cc:8:16: note: declared here 
typedef struct Vector { 
      ^

und weil sie alle gleich ich bin sicher, wenn ich herausfinden, wie man beheben Ich werde sie alle ..

Die compilor sagt Ihnen, Sie sind Verwenden Sie den Typ Namen an Orten, wo Variablenname sein sollte. So zum Beispiel für den ersten Fehler sollte es nur delete numbers; gibt es auch Orte, wo Sie gerade den Variablennamen fehlen und nur Typen, bei denen beide oder nur die Variablennamen sein sollten.
