Need help learning the loop/do while loop

[jlouang]

so i'm stuck in creating a do/while menu doing this.

menu option 1 - use the for loop

menu option 2 - use the while loop

menu option 3 - use the do/while loop

in each option, print the numbers from 1 to 10

I made my functions like this. Anyone know how to do this?
the code on the bottom is just a example the teacher show us for do/while

[HTML]#include // needed for cin/count
#include // needed for math functions
using namespace std;

/****************************
* prototypes //declared function so main can find
*****************************/
void option01();

int main () // prototype to main
{
char option;
do
{
cout << " WYZ Company \n\n";
cout << " 1 - for loop \n\n";
cout << " 2 - while loop \n\n";
cout << " 3 - do while loop \n\n";
cout << " 4 - stuff01 \n\n";
cout << " 5 - stuff02 \n\n";
cout << " 9 - exit \n\n";
cout << "enter desired processing option here: [ ]\b\b";

cin >> option;

switch(option)
{
case '1': option01();
break;
case '2': cout << "you entered option 2\n";
break;
case '3': cout << "you entered option 3\n";
break;
case '4': cout << "you entered option 4\n";
break;
case '5': cout << "you entered option 5\n";
break;
case '9': cout << "we'er otta here\n";
break;
default: cout << "wrong code dummy\n";
} // end switch
}while(option != '9');
system("pause");
}
void option01()
{
cout << "you entered option 1\n";[/HTML]

Just embed the switch statement to activate the menu choice within a do/while loop as indicated in the instruction

do
{
   //display menu
   switch(choice)
   {
       case 1: 
           //use for loop
           break
       case 2:
          //use while loop
          break
       case 3:
          //use do/while loop
          break
       case 6:
          //exit
       default
         //output information to user
     }//end switch
   }while (choice != 6)

I did it like this but it seems not to be working. anyone know the problem

[HTML]void option01();

int main () // prototype to main
{
char option;
do
{
cout << " WYZ Company \n\n";
cout << " 1 - for loop \n\n";
cout << " 2 - while loop \n\n";
cout << " 3 - do while loop \n\n";
cout << " 4 - stuff01 \n\n";
cout << " 5 - stuff02 \n\n";
cout << " 9 - exit \n\n";
cout << "enter desired processing option here: [ ]\b\b";

cin >> option;

do
{
//display menu
switch(option)
{
case 1: cout << "you entered option 1\n";
//use for loop
break;
case 2: cout << "you entered option 2\n";
//use while loop
break;
case 3: cout << "you entered option 3\n";
//use do/while loop
break;
case 6: cout << "you entered option 9\n";
//exit
default: cout << "wrong code dummy\n";
//output information to user
} //end switch
}while (choice != 6)
system("pause");
}
void option01()
{
cout << "you entered option 1\n";
}[/HTML]

When you say something isn't working, it suggests that the code even compiles, which it doesn't. Does this work the way you expect?

#include <iostream>

using namespace std;

int main()
{
  int option;
  do
  {
    cout << "             WYZ Company\n\n";
    cout << "          1 - for loop\n\n";
    cout << "          2 - while loop\n\n";
    cout << "          3 - do while loop\n\n";
    cout << "          4 - stuff01\n\n";
    cout << "          5 - stuff02\n\n";
    cout << "          6 - exit\n\n";
    cout << "enter desired processing option here: [ ]\b\b";

    cin >> option;

    //display menu
    switch(option)
    {
    case 1: cout << "you entered option 1\n";
      break;
    case 2: cout << "you entered option 2\n";
      //use while loop
      break;
    case 3: cout << "you entered option 3\n";
      //use do/while loop
      break;
    case 6: cout << "you entered option 6\n";
      //exit
      break;
    default: cout << "wrong code dummy\n";
      //output information to user
      break;
    } //end switch
  }while (option != 6);
  system("pause");   
}

cout << static_cast <char >(I)<<"  ";

here my qustiion is why we use thisfor(int i=65;i<=90;i++)statment for a b c d e................ make me clear plz
