Condition Components

What basic ideas underlie a structured conditional statement?

• Condition to test
• Statement block
• Else (optional)

C example

        if ( a > b )
        {
            do_something();
            do_anotherThing();
            do_aThirdThing();
        }
        else
        {
            do_somethingElse();
            do_anotherOtherThing();
        }

What about loops?

• Condition to test
• Statement block
• Assumption that when the condition is false, we jump to the statement after the block

C example

        while ( a > b )
        {
            do_something();
            do_anotherThing();
            do_aThirdThing();
        }

        /* Code after loop */

But assembly languages don't have blocks!
