I'm new to programming <pre class="prettyprint"><code>if( (N%2==0) && (6<=N<=20) ) </code></pre> Throws the error below The operator <code><=</code> is undefined for the argument type(s) <code>boolean</code>, <code>int</code> Please help me fix it.

You can't compound the statement like that. You need to <code>&&</code> it. For example, <pre class="prettyprint"><code>if ((N % 2 == 0) && (6 <= N && N <= 20)) {...} </code></pre> The reason you get the error is the first condition of <code>6 <= N</code> resolves to a <code>boolean</code> and you then attempt to check if a <code>boolean</code> is <code><=</code> to an <code>int</code>. That does not compute.

basic if statement, operator <= undefined

You can't compound the statement like that. You need to && it.

For example,

if ((N % 2 == 0) && (6 <= N && N <= 20)) {...}

The reason you get the error is the first condition of 6 <= N resolves to a boolean and you then attempt to check if a boolean is <= to an int. That does not compute.
