    if/break statement

    Hi @all

    I have an if statement in my prog. I want my program ends if my if statement returns false.

    In order to end my prog. I used break but g++ compiler says I should put them in a loop or switch statement.

    for example, can I write a statement like without putting them in a loop;

    Code:
    if (isalpha(chr1)
       cout <<ch1<<" is a char "<<endl;
    else
    {
        cout <<ch1<<" is not a char "<<" quitting. "<<endl;
        break;
    }
    thanks

    I knew that I had to use loop or switch. but I didn't want to put a loop or switch. I wrote here because I was looking another way but I guess I have to use loop or switch..

    Thank you

    In a battle with the compiler. the compiler will most likely always win.

    Um... return 0;?
    I'd think that'd be the right answer.

    break can only be used to end a loop. Use exit() or return.

    Code:
    if (isalpha(chr1)
       cout <<ch1<<" is a char "<<endl;
    else
    {
        cout <<ch1<<" is not a char "<<" quitting. "<<endl;
        break;
    }
    It seems to me like you check chr1, but in your cout you write ch1. An accident?
