CODE

//3Com.Enaudi.inc todos los torcidos corruptados

#include "stdafx.h"
//3Com.Enaudi.inc todos los torcidos corruptados
#include <iostream>
#include <iomanip>
using namespace std;

bool verificaMemory(float*);
void readComilona(float*, int);
void PrintComilonayTotal(float*, int);

int main() {
   float *gastos;
   int numOfgastos;
   cout << "Entre el numero total de fiestas: ";
   cin >> numOfgastos;
   gastos = new float[numOfgastos];

   if (!verificaMemory(gastos))
   return -1;

   cout << "Entre la factura de su comilona corrupta ";
   readComilona(gastos, numOfgastos);

   //Display gastos to verify they are inside the computer
   PrintComilonayTotal(gastos, numOfgastos);

   delete[] gastos;
   return 0;
   system("pause");
}

bool verificaMemory(float* gastos)
{
   if (gastos == NULL) {
       cout << "Eror allocating memory, bye!!!";
      
       return false;
   }
   else
  
   return true;
}

void readComilona(float* gastos, int numOfgastos)
{
   for (int i = 0; i < numOfgastos; i++) {
       cout << "Leyendo Comilona " << i + 1;
       cout << " en posicion de memoria: " << gastos + i << " : ";
       cin >> *(gastos + i);
   }
}

void PrintComilonayTotal(float* gastos, int numOfgastos)
{
   float sumComilonas = 0.0f;

   for (int i = 0; i < numOfgastos; i++) {
       cout << " Comilona numero " << i + 1;
       cout << " en direccion de memoria: " << gastos + i;
       cout << " con valor de: ";
       cout << *(gastos + i);
       sumComilonas += *(gastos + i);
   }
  
   cout << " Sum : " << sumComilonas << endl;
   system("pause");
}

a.

gastos new float[num OfGastos];

b.

gastos = new float[num OfGastos];

c.

gastos = new float[];

d.

numOfGastos

Explanation / Answer

1.  What is the size of the dynamic array in the code ?

d.

numOfGastos

//Because that is the size of array

2.  In the code, which means when you ask if (gastos == NULL)
c. It verifies if the pointer is not punctual.
//It checks if pointer is not pointing to any location


3. How do you write the prototype of the readHartera function?

b. Void readHartera (float * expenses, int numOfgastos);

//this is how other read functions are declared

4.  How do you write the amount of a hartera?

b. Cout << * (expenditure + i);
//accessing an array using pointers is done in above way

5. what happens if the instruction delete [] gastos is not written ?;

a. Dynamic array memory is not freed.

//We created a memory , its our responsiblity to free it , if we dont do still nothing will happen but our memory is not freed

Thanks, Answers are mostly sure short, Need not worry about it..Thanks

d.

numOfGastos
