Go4Expert - C++ x,y chart

Hey guys, thanks for viewing my problem,,

i am currently working on a program and i am trying to input a menu to run with a template i have i am having trouble looping the menu with the template the program is an X,Y plotter i have a template up and running but i just cant get the menu to function with the template some help will be greatley appreciated or if somone could teach me step's here it goes:

The template

Code:

#include <iostream>             

#include <stdio.h>                   

#include <fstream>



using namespace std;  



int row = 0; int col = 0;

char Array [21][75];





void Reset(){        // the initilize function call it like this when you need it Reset();



  for (row = 0; row < 21; ++row){

          

    for (col = 0; col < 75; ++col)

    Array[row][col] = '-';



  col = 0;

  }   

};



void Display(){     // Displays the graph call it like this when you need it Display();

     

    for (row = 21; row > 0; --row){

      for (col = 0; col < 75; ++col)

        cout << Array[row][col];

    

     col = 0;

     cout << "\n";

    }   

} 



void selectfile(){ // lets them select a file call it like this when you need it selectfile(); 

     

     system("cls");

     ifstream myfile;     

     int Selection;

     

     // read a input from the user and put in either 

     

     // this         myfile.open("circle.txt");   

     // or this      myfile.open("square.txt");   

                                                     

     

     while(!myfile.eof()){           // loops through the file and reads it into the graph   

         myfile >> col;                  

         myfile >> row;

         Array[row][col] = '*';  

                 

                 }

   

}



void readkeyboard(){   // loop this code until they enter -99 in your own way

                           // call this function when you need it like this readkeyboard();

     

     

     cout << "\nPlease enter row: ";

     cin >> row;

     

     cout << "\nPlease enter column: ";

     cin >> col;



     Array[row][col] = '*';



}

    

void exit(){

     

ofstream myfile1, myfile2;

    

    myfile1.open("XYCanvas_StudentID.txt");     // put your number in here   

    

    for (row = 21; row > 0; --row){

      for (col = 0; col < 75; ++col)

       myfile1 << Array[row][col];

    

     col = 0;

     myfile1 << "\n";

    }     

  

  myfile1.close();

  myfile1.clear();

     

  myfile2.open("Prog2_StudentID.txt");          // and your number in here

  myfile2 << "name and number"; // name and number

     

  myfile2.close();

  myfile2.clear();

}



void Scale(){



int Scaling;

     

     cout << "Scaling figure? ";

     cin >> Scaling;

     

  for (row = 0; row < 21; ++row)

  {

      for (col = 0; col < 75; ++col){

         

         if (Array[row][col] == '*'){

                                 

             Array[row][col] = '-';

             Array[row*Scaling][col*Scaling] = 'X';

             }

             

         }

         col = 0;

         }





  for (row = 0; row < 21; ++row)

  {

      for (col = 0; col < 75; ++col){

         

         if (Array[row][col] == 'X')                          

             Array[row][col] = '*';          

             

         }

         col = 0;

         }

                  





}





void Shift(){

     

     

     int shift_up, shift_down;

     

     cout << "\nhow much up? ";

     cin >> shift_up;

     cout << "\nhow much up? ";

     cin >> shift_down;

     

  for (row = 0; row < 21; ++row)

  {

      for (col = 0; col < 75; ++col){

         

         if (Array[row][col] == '*'){

                                 

             Array[row][col] = '-';

             Array[row+shift_up][col+shift_down] = 'X';

             }

             

         }

         col = 0;

         }





  for (row = 0; row < 21; ++row)

  {

      for (col = 0; col < 75; ++col){

         

         if (Array[row][col] == 'X')                          

             Array[row][col] = '*';          

             

         }

         col = 0;

         }

     

     

     

     

     }



int main(){

    

    // just a little test on the already complete functions

    Reset();

    Display();

    system("pause");

    

    

    

    

    // menus supposed 2 go here??!?

    

    

    

    };



The menu looks like this



void showMenu()



{

        cout<< "\t\tC++ XY plotter Menu\n\n";

        cout<< "\t1. Display XY plot\n";

        cout<< "\t2. Read input from file\n";

        cout<< "\t3. Read input from keyboard\n";

        cout<< "\t4. Clear XY canvas\n";

        cout<< "\t5. Scale/Shift figure\n";

        cout<< "\t6. Exit program\n";

        cout<< "\t7. Credits\n";

        cout<< " Enter your choice: "; 

}

any chance of any c++ enthusiasts having a crack at this or helping out?

if the menu could function with the template this program will be running perfectly.

any help will be greatley appreciated!:worried:
