C++プロシージャで「値を参照していません」エラー

Question

すべてのエラーはまったく同じもので、理由を理解できないようです。どんな助言も役に立つでしょう。手続き型のC++を使用する必要があります。

#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; 
} 

私のエラーはすべて同じです。そして、ここで彼らは

vecalc.cc:49:12: error: 'Vector' does not refer to a value 
    delete Vector *numbers; 
     ^

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 { 
      ^

あり、それらはすべて同じであるので、私は私は1つを修正する方法を見つけ出す場合、私はそれらをすべて取得すると思うよ。..

compilorはあなたが、あなたを語っていますタイプの名前をの変数名にする必要があります。 例えば、最初のエラーの場合は、ただdelete numbers;でなければなりません。変数名がまっすぐに欠落していて、変数名のみまたは両方が必要な型だけがある場所もあります。
