do...while

I thought I understood the tutorial well enough, but I keep getting an error when I try to compile. The error states "20 C:\transfer\cpp\junk\main.cpp `lm' undeclared (first use this function) " Dev-cpp highlights the line including

Code:

    } while (lm == 1);

when referencing this error. Thank you for your help. PS: trying to compile on win xp pro with dev-cpp 4.9.9.2

Code:

#include <iostream>

using namespace std;

int main(int argc, char *argv[])
{
    do {    
        int number; 
        int lm = 0;
        system("clear");
        cout<<"Enter a number between 1 and 10: ";
        cin>>number;
        for (int cntr = 1; cntr <= number; cntr++)
        {
            cout<<cntr<<"\n";
        }
        cout<<"\n\n";
        cout<<"Go Again?\n1. Yes\n2. No\n";
        cin>>lm;
    } while (lm == 1);
    cout<<"\n\n\n\n";
    system("Pause");
}

Move the declaration outside the loop.

Code:

    int lm = 0;
    do {

Wonderful, thank you so much. BTW, is this a common way to loop the main section of a program? Do many other programmers do it this way? It seems suited perfectly for that use.

It's pretty standard, but for clarity it is often better to break the actual loop body into its own function.
