Question

Language: C++

NEEDS TO WORK IN VISUAL BASIC

The code is broken and loops in a few places please fix it

#include<iostream>
using namespace std;
//function declaration
void EnterRents(int*, int);
void displayRents(int*, int);
void selectionSort(int*, int);
int sumRents(int* temp, int size)
{
   int sum = 0;
   for (int i = 0; i < size; i++)
   {
       sum += *(temp + i);
   }
   return sum;
}
void Displaymemory(int* temp, int size)
{
   /*int memory;
   memory=sizeof(temp)*size;
   cout<<memory;*/
   for (int i = 0; i < size; i++)
   {
       cout << &temp[i] << " ";
   }
}
//main drive
int main()
{
   int n;

   char c;

   cout << "Enter a for enter the rents amounts" << endl;
   cout << "Enter b to display rents amounts" << endl;

   cout << "Enter the number of amount items stored in Amout array " << endl;
   cin >> n;
   // we should create the array with help of new if we are giving size dynamically
   int* arr = new int[n];
   //while statement with switch case to call declared function
   while (1)
   {
       cout << endl;

Solution :

Following is the corrected code :

#include<iostream>
using namespace std;
//function declaration
void EnterRents(int*, int);
void displayRents(int*, int);
void selectionSort(int*, int);
int sumRents(int* temp, int size)
{
   int sum = 0;
   for (int i = 0; i < size; i++)
   {
       sum += *(temp + i);
   }
   return sum;
}
void Displaymemory(int* temp, int size)
{
   /*int memory;
   memory=sizeof(temp)*size;
   cout<<memory;*/
   for (int i = 0; i < size; i++)
   {
       cout << &temp[i] << " ";
   }
}
//main drive
int main()
{  int n;
   char c;
   cout << "Enter a for enter the rents amounts" << endl;
   cout << "Enter b to display rents amounts" << endl;
   cout << "Enter c to sort the rents amounts" << endl;
   cout << "Enter d to total rents amounts" << endl;
   cout << "Enter e to display memory alloaction" << endl;
   cout << "Enter f to exit" << endl;
   cout << "Enter the number of amount items stored in Amout array " << endl;
   cin >> n;
   // we should create the array with help of new if we are giving size dynamically
   int* arr = new int[n];
   //while statement with switch case to call declared function
   while (1)
   {
       cout << endl;
       cout << "Enter your choice" << endl;
       cin >> c;
       switch (c)
       {
       case 'a':
           cout << "Enter the " << n << " no of Rents amount" << endl;
           EnterRents(arr, n);
           break;
           //Other switch cases
       case 'b':
           cout << "Display Rents" << endl;
           displayRents(arr, n);

           break;
       case 'f':
           cout << "f entered by user to exit" << endl;
           exit(1);
       default:
           cout << "Invalid input.";
           break;

       }
   }

   return 0;
}
//function definition

{
   for (int i = 0; i < n; i++)
   {
       cout << *(arr + i) << " ";
   }
}
//void selectionSort(int*,int)
void selectionSort(int* pointer, int size)
{
   int* i, * j, swap;
   int* end = NULL;

   if (size < 2 || pointer == NULL)
       return;

   end = pointer + size - 1;

   for (i = pointer; i < end; i++)
   {
       for (j = i + 1; j <= end; j++)
       {
           if (*j < *i)
           {
               swap = *i;

               *j = swap;
           }
