here is my first question on this board..
I have been learning c++ for 6 weeks now so I'll take all the advice I can get. so most of this code is experimenting with diffrent things.. like the license output is jsut so I caould play with diffrent ways of doing it. not that this crappy code needs copywrite protection
.
I have a program that uses an array to collect Poll data. and I have two output methods
one looking like this
Code:
200 - 299 1
300 - 399 0
400 - 499 6
500 - 599 1
600 - 699 2
700 - 799 0
and one that looks like this..
Code:
200 - 299 *
300 - 399
400 - 499 ******
500 - 599 *
600 - 699 **
700 - 799
my problem is I need to clear the array between displays or it just re-adds the data.
not I am populating a file with the initial data, and the file is read and calculations are done to the file.
here is the whole program to help.
warrnig its long, and I have not cleared out unused variables yet.
Code:
//csi 245 C++
//William S. Huskey
//A way overboard version of assinment
//header files
#include <iostream>
#include <fstream>
#include <cstdlib>
#include <iomanip>
//declare name space
using namespace std;
//Function Prototype
// needs to pass to compiler options , for Gcc its -DUNIX or -DWIN32 VC++ ?? no clue
void clear_screen();
//information functions
int PrompUser (const string&);
//output functions
void PrintLicense ();
void SalesInfo ();
void StarBar();
void GraphOut(const int[], const int[], const int);
void PrintToScreen( int[], const int[], const int);
void WelcomeScreen();
void SalesDump();
//global variables
const char* file_name = "salesinfo.txt"; //file where sales persons information will be stored
const char* LicenseFile = "license.txt"; //GNU GPL target
//main funtion
int main ()
{
//local variables
int UserInput = 0, holder = 0, MenuInput = 0;
const int array_size = 9, poll_size = 10;
bool Loop = true;
//arrays
int salaryRange [array_size] = {200,300,400,500,600,700,800,900,1000};
int Polldata [poll_size] = {0};
//create file salesinfo.txt
ofstream newfile (::file_name);
if (newfile.is_open())
{
newfile << " ";
newfile.close();
}
//menu
while (Loop == true)
{
clear_screen();
//header for menu
WelcomeScreen();
//menu chooices
clear_screen();
