Course C Initial – Libraries


Hello again! As promissed, here’s a table of some libraries in C Language. Use it how many you need!
Name
Definition
<assert.h>
Contains the assert macro, used to assist with detecting logical errors and other types of bug in debugging versions of a program.
<complex.h>
A set of functions for manipulating complex numbers.
<conio.h>
Different functions.
<ctype.h>
Defines set of functions used to classify characters by their types or to convert between upper and lower case in a way that is independent of the used character set (typically ASCII or one of its extensions, although implementations utilizing EBCDIC are also known).
<errno.h>
For testing error codes reported by library functions.
<fenv.h>
Defines a set of functions for controlling floating-point environment.
<float.h>
Defines macro constants specifying the implementation-specific properties of the floating-point library.
<inttypes.h>
Defines exact width integer types.
<iso646.h>
Defines several macros that implement alternative ways to express several standard tokens. For programming in ISO 646 variant character sets.
<limits.h>
Defines macro constants specifying the implementation-specific properties of the integer types.
<locale.h>
Defines localization functions.
<math.h>
Defines common mathematical functions.
<setjmp.h>
 Declares the macros setjmp and longjmp, which are used for non-local exits.
<signal.h>
Defines signal handling functions.
<stdalign.h>
For querying and specifying the alignment of objects.
<stdarg.h>
For accessing a varying number of arguments passed to functions.
<stdatomic.h>
For atomic operations on data shared between threads.
<stdbool.h>
Defines a Boolean data type.
<stddef.h>
Defines several useful types and macros.
<stdint.h>
Defines exact width integer types.
<stdio.h>
Defines core input and output functions.
<stdlib.h>
Defines numeric conversion functions, pseudo-random numbers generation functions, memory allocation, process control functions.
<stdnoreturn.h>
For specifying non-returning functions.
<string.h>
Defines string handling functions.
<tgmath.h>
Defines type-generic mathematical functions.
<threads.h>
Defines functions for managing multiple Threads as well as mutexes and condition variables.
<time.h>

Course C Initial 7th – Training with Math

Lesson 7. Now, as promised in previous lesson, we’ll go to make some algorithms to practice all knowledge that we learned up to here. First: Make an algorithm that reserves 3 numbers by user and sum them, after show the result. For this, we first make the structure as showed below. How we can see, this is the basic structure of a software in C language. Now, we’ll create the variables for it: Okay, the variables was created. Now we’ll input the values for them with printf’s and scanf’s how you can see below: Note: always use return 0; in the end function. Now we’ll create a new variable called Result that will be the sum of Num1, Num2 and Num3 how you can see below. After we’ll print Result. That’s finished, we have an algorithm that calculates the sum between 3 numbers. Now, practice this algorithm, write and test yourself, test it change the math operators and joyful. You cou

Course C Initial – 3rd Variables Part. 1

Lesson 3 Part. 1. Hello again! As promised in the previous class, now I speak about variables in C language. First, what’s a variable? The answer is important because it will help us to learn more and use them. Definition: capable of being varied or changed; alterable. (source: www.dictionary.com). That’s the definition that we need! So, there’s some variables types in C language. They’re: Global; Locale; Constant; Volatil e; Inside each one of those cases, we have in resume, 4 type that can be represent in each or all those cases. Below, you’ll can see its names. c har – ‘a’, ‘b’, ‘c’,...; int – 1, 2, 4, 7,...; float – 7.553279, 8.856347,...; double – 9.5896324789632, 10.5885569347799,... ; There’s variations inside each format, but we’ll see in the future. How we can see above, the type data that the variables types represent. Char is for character data, int is for integer, float is for floating point

Course Python For Life 3 – Input Command

As was promised in the previous lesson, now we’ll see the input command in python language, it’s a smaller lesson, next lesson, we’ll see variable’s concepts in Python that’s different of others languages. First step: - I recommend that you use the output command. In python, input command requires a variable. There’s two ways to use this command, they’re: - with print. - without print. Note: In python, you don’t need to use ‘;’ in the end of a line, it works, but it isn’t required. With print: print(‘type any key...’) a = input() Test it yourself! See it in the editor: Run and see what happen. It required that the use type any thing by the keyboard. Below, see it being ran. But there’s other way to do this code, see below: a = input(‘Press any key...’) Test it yourself! Think about it, that’s the way to learn! The appearance is:
