«Не ссылается на значение» в процедурной процедуре C ++ ⇐ C++

[Anonymous]

Все мои ошибки одинаково, и я не могу понять, почему. Любой совет был бы полезным. Я должен использовать процедурный C ++. < /P>

#include

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 size; i++) {
bigger = numbers; // 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 size; i++){
numbers = numbers + Elem;
}
return numbers;
}

И потому что все они одинаковы, я уверен, если я выясню, как его исправить, я получу их все .. < /p>
