Question

I need a program to do the following:

1) Asks the user for the output filename.

2) Asks the user for how many records are to be created.

3) A function that accepts an integer and returns a string with any
one of 5 strings containing the name of the object. For example object number 3 might be
"Pen". Object 4 might be "Paper".

4)Another function that has no parameters and returns a random integer
number for choice. That choice number will be a number that helps choose which object
we are going to create.

5)Another function that has no parameters and returns a random
positive number from 0 to 999.99. These will be our coordinate numbers used for the x y
and z portions of the the file.

6) Program displays each created record once it is created.

Example output might look like this;

How many records are to be created? 3
Pen 2013.3 100.9 13.008
Paper 100.09 32.7 45.01
Computer 10.0 100.0 10.0

Thank you for whoever takes the time to go through this. I will give highest points possible. Use C++ and basic codes as well. Introductory course.

Explanation / Answer

#include <iostream>
#include <stdlib>
#include <time>
#include <fstream>

using namespace std;

// A function that accepts an integer and returns a string with anyone of 5 strings containing the name of the object
string objName (int n)
{
   string result;

   switch (n)
   {
       case 1:
           result = "Desk";
           break;
       case 2:
           result = "Lamp";
           break;
       case 3:
           result = "Pen";
           break;
       case 4:
           result = "Paper";
           break;
       case 5:
           result = "Computer";
           break;
   }
   return result;
}

// Another function that has no parameters and returns a random integer number for choice.
int numGenerator()
{
   int num = 0;

   num = rand() % 5 + 1;

   return num;
}

// Another function that has no parameters and returns a random positive number from 0 to 999.99
double genPos ()
{
   double num;

   num = (double) rand()/RAND_MAX;

   return (num * 100);
}

int main()
{
   string filename;
   int    rec;
    ofstream file;
    double x, y, z;
    string obj;

   // Asks the user for the output filename
   cout << "Please enter filename" << endl;
   getline(cin, filename);

   // Asks the user for how many records are to be created
   cout << "Please enter how many records are to be created" << endl;
   cin >> rec;

   // seed
   srand (time(NULL));

   // Program displays each created record once it is created
   file.open(filename.c_str());
   for (int i = 0; i < rec; i++)
   {
       obj = objName(numGenerator());
       x = genPos();
       y = genPos();
       z = genPos();

       cout << obj << " " << x << " " << y << " " << z << endl;
       file << obj << " " << x << " " << y << " " << z << " ";

   }
   file.close();
   return 0;
}
