<h3>Conditionals &amp; Blocks within Braces</h3>


<h4>2 Tasks for this Practice Set:</h4>

<ol>
    <li>Use conditionals to create code which outputs a sentence to the console stating whether the variable <i>x</i> is greater to, equal to, or less than zero. It should work for any numeric value of x</li>
    <li>Look at the code in this section, and fix it so that the output is correct. In your console, it should look like this (Hint: it involves braces) :
        <img src="http://courses.dce.harvard.edu/~cscie3/img/captains.png" title="program output" style="width:80%;padding-top:.5em;">
    </li>
</ol>

JavaScript

"use strict";

// Insert your code for #1 here
console.log("1. IF cond. test:")

var x = Math.floor(Math.random()*20) - 10;

if (x > 0 ) {
	console.log("  " + x + " > 0.");
} else if (x < 0) {
	console.log("  " + x + " < 0.");
} else {
	console.log("  " + x + " = 0.");
}

// Insert your code for #2 here
console.log("2. FOR loop test:")

var myCaptains = ["James T. Kirk", "Jean-Luc Picard", "Katherine Janeway"];

for (var i = 0; i < myCaptains.length; i++) {
		console.log("  The Captain in Capitals is " + 	
    	myCaptains[i].toUpperCase() + ".");
}

console.log("  " + myCaptains.length + " captains have been capitalized.");
