intro

after we setup and tested CODE::"BLOCKS ( on win 10 PC or Raspberry Pi )
now you can start learning C coding: variables / math / if / for / ...
but not in a lifetime you could write a program for desktop,
with a window , operation menu ( buttons..), file handling , graphic output,
for this you need to use one of the additional GUI tools and libraries, what come with this IDE as ready templates, like:
QT , wx, GTK, win32GUI
but the tools you need to install additionally, basically the library and a window designer tool.

pls. understand that i am NOT a C programmer,
after 30 years in the industry as computer & instrument engineer,
i play many years
* C++ Arduino coding,
* Processing JAVA & JS,
* Python apps
also many other things, including
* web- server and design...
but i am actually not qualified to make a C Tutorial!

after have the CODE::BLOCKS installation tested, by use
+ new project
+ select console application
+ build
+ run

FOR loop

we start with our first code: a easy FOR loop to print lines
C_For_loop.txt

---

keyboard input

we try a keyboard input of two numbers and print out the result of a+b=
C_keyboard_input.txt

---

our first function

now we do same, but try to put the sum calculation and the print into one function
C_function.txt

---

many function

when we use many function with good naming our main program stays short
and is easy readable.
C_many_function.txt

---

time lib

start to play with the TIME library, first print current time
C_time.txt

---

action every second

try a C_program what prints lines every second
C_timed_loop.txt

---

timer function

and a repeating timer function
C_timer_function.txt

---

keyboard text to file

get a string ( line ) from keyboard and save it in ( at end of ) a file (append)
C_string_keyboard_to_file.txt

---

array

make a program what runs forever, until enter 'e' from keyboard
declare a static / array long 10 / filled with any integer numbers
on keyboard entry 0 .. 9 print this number and also the value from the array with this as the index
C_int_array.txt

---

struct

now we play already variables and arrays, but how about class?
well while C++ / JAVA ... knows them C closest thing is a struct,
with this you can build a multi type record.
and making a array of struct should be something you can call database ( or table )
as used for JSON or CSV files... or after you combine it with functions ( C++ call it methods )
a class alike.

make a program what creates a record for books ( title / author / book_id )
and a array of it ( database / filled manually )
add a record print function
C_struct.txt


here we are at the end of the basic C tutorial.
