An introductory course on computers and programming focusing on logic building and problem-solving skills through hands-on exercises.

This language-agnostic course is your guide to programming and acquiring problem-solving skills. You will start reviewing the anatomy of computers and the binary number system. You will then look at the lifecycle of a program before moving on to the core concepts of programming. Overall, the primary focus of this course is logic building within the context of computer science and programming.

Throughout each chapter, you will get hands-on experience with exercises and quizzes to solidify what you’ve learned. If you’re looking to build strong programming fundamentals then this course is the perfect place to start.

If `n1`, `n2`, and `n3` are equal to 5, 7, and 1, respectively, what is the output of the following pseudocode:

```
INPUT n1, n2, and n3
IF n1 > n2
    temp = n1
ELSE
    temp = n2
IF n3 > temp
    num = n3
ELSE 
    num = temp
OUTPUT num
```

If <code>n1</code>, <code>n2</code>, and <code>n3</code> are equal to 5, 7, and 1, respectively, what is the output of the following pseudocode:
<pre><code>INPUT n1, n2, and n3
IF n1 &gt; n2
 temp = n1
ELSE
 temp = n2
IF n3 &gt; temp
 num = n3
ELSE 
 num = temp
OUTPUT num
</code></pre>

```
INPUT n
IF n == 0
 OUTPUT zero
IF n >=0
 OUTPUT positive
IF n < 0
 OUTPUT negative
```

```
INPUT n
IF n == 0
 OUTPUT zero
IF n > 0
 OUTPUT positive
IF n < 0
 OUTPUT negative
```

```
INPUT n
IF n == 0
   OUTPUT zero
ELSE-IF n > 0
   OUTPUT positive
ELSE
   OUTPUT negative
```

Which of the following options contain the correct pseudocode to determine if a number *n* is positive, negative, or zero? Choose multiple options if they apply.

What is the output of the pseudocode below if you buy a pair of jeans? (`item` = jeans, `quantity` = 1)
```
INPUT item and quantity
If item == shirt
    discount = 20%
ELSE
    IF quantity >= 5
        discount = 30%
    ELSE
        discount = 5%
OUTPUT discount
```

What is the output of the pseudocode below if you buy a pair of jeans? (<code>item</code> = jeans, <code>quantity</code> = 1)
<pre><code>INPUT item and quantity
If item == shirt
 discount = 20%
ELSE
 IF quantity &gt;= 5
 discount = 30%
 ELSE
 discount = 5%
OUTPUT discount
</code></pre>

What is the output of the pseudocode below if you buy twenty shirts? (`item` = shirt, `quantity` = 20)
```

ELSE
    IF quantity >= 5
        discount = 30%
    ELSE
        discount = 5%
OUTPUT discount
```
