Decision / Branch in C Programming

Hello , today im going to share about Decision making / branch in C Programming
In my Journey of learning C, what i used to make decision / branch is :
- IF - Else
- Switch - Case

If -Else :

heres a Flowchart of decision making to help you understand.
 

now lets move to the Code. im using Code::Blocks, Download it for free, see the tutorial in my last week's post.
this Tutorial is showing about giving a Grade A/B/C to According to your Score

 

Switch-Case  :

 

 and for the Code :

And this is what Happened if i dont use break;

 

Hope This pst will help.

Peace!

C Data Types , Input & Output.

1. Data Types

C provides various data types that can be used in your programs.  

As a beginner , I  commonly use:

• int for most variables and "countable" things (for loop counts, variables, events) , Format :  %d
• char for characters and strings , Format :%c / %s

• float for general measurable things (seconds, distance, temperature) , Format  %f  

• double  as i know ,almost the same as Float, but more precise , Format %lf

 There are still a lot of data types in C , You can check wikipedia for more precise:

https://en.wikipedia.org/wiki/C_data_types 

Here is a few  i get from other resources :

https://developer.mbed.org/handbook/C-Data-Types 

2. Input & Output

Input    : In  programming language input means to feed some data into program. This can be given in the form of file or from command line.

Output : In any programming language output means to display some data on screen, printer or in any file.



In input , I mostly use function "scanf" in the command line
 and In output , the example i can give to you is function "printf". as a beginner ill show you the example of all the above explanation in 1 pic. this the tutorial for calculating the volume of a Sphere:
