In any programming language, you will often need to make decisions. This will take the program into different functions depending on the answer of a question, result or evidence. This is called Control Flow and it is a collection of powerful instructions for decision making. Without them, electronic devices couldn't be able to make decisions upon evidence.

What is Control Flow?
You might be asking yourself: what is the evidence? It is called binary values because they can only be either 1 or 0 and they are the result of a question, like:
- Is result A higher than result B?
- Is result B equal to 100?
- Is result A true?
If the answer is affirmative or 1, the code will execute a piece of code; if it is negative or 0, the code will execute another piece of code.
Types of Control Flow
There are different kinds of Control Flow instructions.
- one selection: if(if-else).
- multiple selection: switch.
- loops: while, do, for.
- jumps: break, continue.
I'm going to place here the Control Flow instructions in different sections as I compose them.
Examples of Control Flow
if
One of the most basic functions available is ‘if‘. A simple question where the answer is either true (1) or false (0); depending on the answer, a certain code will be executed. Click in the link below to read about it.
switch
For repetitive decision making, there is Switch. Excellent for programming and to leave the clutter behind. Click in the link below to read about it.
while
For repetitive tasks which require a sequence, ‘while‘ is frequently used. Click in the link below to read about it.
