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.

Introduction to Computers & Programming

Programming language independent and subjective

What is wrong with the following pseudocode to output the cube of a number *n*?

```
INPUT n
cube = n * n * n
```

What is wrong with the following pseudocode to output the cube of a number n?
<pre><code>INPUT n
cube = n * n * n
</code></pre>

What is wrong with the following pseudocode?
```
sum = n1 + n2
INPUT n1 and n2
OUTPUT sum
```

What is wrong with the following pseudocode?
<pre><code>sum = n1 + n2
INPUT n1 and n2
OUTPUT sum
</code></pre>

It indicates the input/output of the program

It indicates the different possible scenarios based on a condition.

The input/symbol is represented by a rectangle

There is no need for the start/end symbol

The process symbol should be used to describe the operation `square = n * n`
