# 5 Basic Coding Concepts Kids Need to Know

5 Basic Coding Concepts Kids Need to Know: Whether you’re just starting out or you’ve been programming for a while, there are a few basic coding concepts you need to know. These concepts are: Iteration, Variables, Sequence, and Loops.

### Variables

During programming, variables are memory locations that store data values. A variable may change its value depending on the information that it is accessed with. Using real-life examples, kids learn how to link the abstract concept of a variable to its concrete forms.

Generally, a variable can have any name, but its type may determine the types of values that it stores. For example, an integer is a number expressed as a decimal number. Likewise, a string can contain any character.

When creating a name, a programmer must decide whether or not the name is alphanumeric, numeric or special. Most languages limit the number of characters that can be used in a variable name. Usually, a variable’s name can only have alphabets, but a few allow underscores (“_”) or whitespace characters.

Variables are a common part of coding. They are containers for values that can be assigned to a computer program’s instructions. In addition, they can be used to bring up stored information. For example, if a player scores a goal in a football match, the score is stored in the variable score. In addition, a variable’s value can be stored in time, such as minutes elapsed or lives that have been lived.

A variable is typically initialized to its default value. For instance, if a computer programmer needs to store ten different visitor names, he or she would create a variable that holds a ten-digit string. This would allow a programmer to refer to the visitorName variable without having to manually enter ten separate values into the program.

### Data types

Having a clear understanding of the different data types is crucial for designing programs. These types specify the operations on data, as well as the types of variable values. They also make it possible to avoid errors during programming.

Data types can be divided into five main categories. These are string, array, value, boolean, and structure. They describe the operations on data and determine the meaning of the data. They are essential for error-free and efficient programming. The basic type is the atomic type, which is composed of a single data item. This type cannot be broken into separate components. The value is a number, which is a sequence of bits.

The other basic types are enumerated types, which are enumerable. They are distinguished from atomic types by their distinct values. These values can be tested for membership. The implementations of enumerated types vary. Some implement them as type-equivalents of integers, while others treat them as an arbitrary value.

Another type is a composite type, which is composed of data items. These can be of the same or different data types. These can be implemented as arrays or stacks. An array is a list of variables, where each item is stored in a certain order.

The value data type is a type of data that is stored on the stack. It can be a numerical value or text. It can be a decimal number, a fractional number, or a float. Arrays are a list of variables that can be accessed using an index. The first item in an array has an index of zero. The rest of the elements are stored in a specific order.

### Sequence

Besides being the oh so enticing subject of the modern day PC, the computer is a machine that needs to be programmed to complete specific tasks. Hence, it is important that the programming be a well thought out and well organized endeavor. Luckily, there are many tools at our disposal to help ensure that our intrepid minions get the job done in the most efficient manner possible.

A good start to the coding challenge is to break up the task into smaller and more manageable chunks. These chunks of code are then called steps. The end result is a well-oiled and highly effective machine that can produce results in record time. The best part is that it isn’t difficult to master. A little bit of practice and a little bit of dedication goes a long way in the programming arena.

It’s not a bad idea to pick out the brains of a child and explain the ins and outs of the coding world one piece at a time. There are many e-books and tutorials to choose from. Some of these are targeted at aspiring programmers while others are aimed at the average Joe. These e-books can be found on the interwebs and in a variety of formats, from PDF to eBooks. Some are free while others will cost you a few bucks. The trick is finding the right ones.

A sequence is a complex series of steps whose main goal is to accomplish a particular task. This may be as simple as a set of steps or as involved as a multi-step program. The trick is to identify the correct order of steps to avoid unnecessary confusion.

### Loops

Almost every programming language incorporates the concept of loops. They are powerful tools to help automate repetitive tasks, save time, and minimize errors. They are also a great way to create complex software.

A loop is a set of instructions that repeats a predetermined number of times. It is an important programming concept to know. It allows for repeated execution of code until a condition changes.

There are two main types of loops in most languages. One is the do-while loop. This is an exit-controlled loop, meaning it will continue to run until it reaches a specified test condition. The other is the while loop, which is an entry-controlled loop, meaning it will begin to execute statements within the loop body only when it reaches a specific test condition.

The loop may be a fun idea, but it is not always easy to get right. This is why it is important to check the loop’s initializations and the conditions involved.

The exercise below asks the user to enter the number of times a loop will be executed. The program will then perform the corresponding calculation and return. It does this by using the += unary increment operator.

The same concept is embodied in the goto statement. The goto statement allows a programmer to jump backwards from the label to the point where the next instruction would have been executed. In this example, the code would be executed ten times.

Another concept is the sequence. This is similar to the loop, but it is implemented with a different order of steps. The first step is to initialize a counter. On each iteration of the loop, the counter will be incremented by one.

### Iteration

Essentially, iteration is the repetition of a sequence of instructions in the same order. This is accomplished with loops. In fact, almost all computer programs use loops. Using loops allows the computer user to avoid copying code, which saves time.

A loop is a sequence of instructions that are repeated until a condition is met. The conditions can be anything, from a nonzero value to a true value. A loop is typically executed using FOR or WHILE statements.

In computer programming, iteration is one of the most important concepts. Its purpose is to eliminate unnecessary steps, which streamlines design and development. It is also a way for programmers to solve problems. For example, when a problem arises, the program will often use a loop to determine the solution.

The ‘while’ statement tells the computer to start the iteration at the specified location. A loop can be either infinite or infinitely nested. The number of iterations is fixed at the beginning of the loop. If the program uses an infinite loop, the computer will continue to run the algorithm until the condition is met.

Infinity loops are commonly used by new programmers. An infinite loop is a loop with no exit condition. An infinite loop can be used to control a traffic light. When a loop reaches its maximum limit, it is instructed to return to the beginning. Iteration is also referred to as recursion.

The complexity of an iteration is determined by calculating the input size and the total number of operations. It is easier to calculate the complexity of an iteration than the complexity of a recursion. The complexity of a loop is also determined by the number of times the innermost statement is executed. When an iteration reaches its end, the post-condition must be properly defined.
