C Programming Tutorial 44 – Coding Challenge

Did you read the last blog? Go read it on Quiz Part 3! Are you new here? Start at the beginning, Intro to C!

You know a lot of the concepts, but now you need to practice writing some code. I am going to give you a small coding assignment. You can give it a try and then compare your answer to mine.

The Assignment:

You have a right triangle, and you are given the length of the smaller sides. Write a program that asks the user for two lengths of a right triangle, and outputs the length of the longest side (the hypotenuse).

C Programming Tutorial 43 – Quiz Part 3

Just as a reminder, up next we will be covering logic, conditionals, loops, and how to make more complex programs. But before this, I think it is important to make sure we have the previous blogs down well. These next blogs and previous blog will quiz you on some parts of C. If you have a hard time answering these question, you might want to review your notes. Are you new here? Start at the beginning, Intro to C!

C Programming Tutorial 40 – How to use the Type Cast Operator

Did you read the last blog? Go read it on Implicit Type Promotion! Are you new here? Start at the beginning, Intro to C!

Now, let’s give an example of explicit conversion:

In this situation, we are splitting the pieces of pizza with our friend. We are trying to figure out how many pieces each person should get.

Both operands are integers, so the result will be an integer. There are two ways we can fix this. First, we can add .0 to the 2. This works, but it will not always work. For example, we could have this:

C Programming Tutorial 39 – Implicit Type Promotion

The previous blog was foundational to this blog, so go read that first! Are you new here? Start at the beginning, Intro to C!

Essentially, casting is when something of a certain data type is converted to a different data type.

This blog is going to be showing examples of both implicit casting and explicit casting. When you study implicit conversion in C, you will likely come across the term promotion.

C Programming Tutorial 38 – Type Casting

Did you read the last blog on Strongly Typed Vs Loosely Typed Languages? Are you new here? Start at the beginning, Intro to C!

In the previous video we mentioned how C was a strongly typed language. Imagine C as a grumpy old man who you owe a dollar bill to. Well, he wants his money now, but all you have is some change.

You look at your change, grab four quarters, and find out that it adds up to exactly a dollar. But unfortunately, you owe him a dollar bill, not just 100 cents. So yeah, he beats you over the head with his cane.

C Programming Tutorial 37 – Strongly Typed Vs Loosely Typed Languages

Did you read the last blog on Operator Precedence? Are you new here? Start at the beginning, Intro to C!

This blog is going to be an introduction to how programming languages consider data types. As we know, there are many data types in C programming. C is an example of a strongly typed programming language. Strongly typed means that every piece of data has a specific type.

Concatenation

Imagine if we stored everything in strings. This would become a problem because the computer would never know how to work with certain data. For example, let’s say we have “5” and “6” and we try to add them. Should the computer add the numbers to be “11”, or should it combine the strings to be “56” (The process of combining two strings like this is known as concatenation).

C Programming Tutorial 36 – Operator Precedence

Did you read the last blog on Assignment Operators? Are you new here? Start at the beginning, Intro to C!

You may have heard from math class of this fancy thing called order of operations. We discussed this in a previous video so I’m not going to waste your time by repeating myself, but I am going to look at the same concept from a bigger point of view.

Precedence and Associativity

The point of the order of operations is to say which operators happen first and from which direction. For example, we know for the c operators, the multiplication happens first. This order in which operators happen is known as precedence.

C Programming Tutorial 35 – Assignment Operators

Did you read the last blog on Increment and Decrement Operators? Are you new here? Start at the beginning, Intro to C!

In the previous blog I showed you how you can add one to a variable.  You can use the ++ operator. I also showed you what to do if you wanted to add more than one to a variable.  For example, we can have something like this:
