different values in while using enum?

**blackgold>>** · 04-26-2004

Hi.
I was wondering is there anyway i can put in different value into my while structure so i don't have to make more switches?
Thanks alot.

p.s. my user defined types in the enum i was thinking could be used in the while structure .

Code:

#include <iostream>
using namespace std;


void started ( void );            // function prototype :1



int option1;


int main()
{

  cout <<"Hi welcome to the driving program" << endl
       <<"\nPlease press: 2 to start engine" << endl;

  while ( ( option1 = cin.get() ) != EOF ) {               // put in different  option in while structure.

     switch ( option1 ) {

        case '2':
           started();
           break;                                           // to exit switch
   }
 }

return 0;
}

void started ( void )            // function def :1
{
   cout << "Engine started" << endl;
}




//enum GEARS { reverse, first, second, third, fourth, fifth }; // starts at 0 and increments by 1

Hmm don´t really understand your problem (be more specific) but I try anyway ^^. A while statement look like this

Code:

while(some condition)
{
statements;
}

The statements will executed as long as some condition is avaluated as true. To exit the while loop you have to

some condition must be evaluated as false
unconditional branch with e.i. break or goto (usually not recommended)

Here is some sample code

Code:

#include <iostream>

int main()
{
bool isLooping = true;
int counter = 1;
while(isLooping)
{
	std::cout << "Counter is now: " << counter << std::endl;
	if (counter == 5)
		isLooping = false;//or just break;
	++counter;
}
return 0;
}
