Condition 2 will only be evaluated if Condition 1 asserted.

If Condition 1 is false, then nothing will happen.
Condition 2 won't be evaluated and Statement 3 won't be executed neither.

If Condition 1 is True then Condition 2 will be evaluated, if false then only Statement 3 will be executed, otherwise both Statements (2 and 3) will be executed.

Hope it helps

You should learn to use a debugger and buy a good C++ book. You can put an else statement after an if, as in

if (conditiond2)
{
statement2
}
else
{
statement3
}

if you don't do that, then statement 3 will always run, because you're asking it to.

In addition, you nested the second condition, thus telling the program to only check it if the first succeeds. Put the second check out side the first check, if you want both to always be checked.

Solution 3

No, because the second if statement only gets looked at if condition-1 is TRUE

Oh, I read that backwards, his question was more simple than I thought, and his example convoluted.

I also missed the second question, and I'm not 100% sure I answered what he was really asking.
