The C Programming Language

1. Chapter 1: A Tutorial Introduction

   • Variables
     • A variable is a memory space where we store information.
       • char- character
       • int-integer number
         • short- short integer
         • long- long integer
       • float- decimal number
         • double- double-precision floating point
   • The For Statement
     • A condition is established and does not stop repeating itself until the condition is false.
       • To close the loop, an increase in the conditional variable is needed.
   • Symbolic Constants
     • They are predefined values ​​that cannot be modified throughout the execution of the program. They are written in capital letters by convention.
   • Character Input and Output
     • getchar( )
       • Reads the next input character from a text stream an returns that as its value
     • putchar( )
       • Prints a character each time it is called
   • Arrays
     • It is a sequence of memory spaces to store information of the same type in them.
   • Functions
     • They are already created code structures that help to lighten the code and improve its readability.

2. Chapter 2: Types, Operators, and Expressions

   • Declarations
     • Escape sequences are formats applied to the output of the results.
       • All variables have to be defined before being used.
   • Arithmetic Operators
     • +, -, *, /, %
   • Relational and Logical Operators
     • > >= < <=
   • Increment and Decrement Operators
     • ++ = +1
     • - - = - 1
   • Bitwise Operators
     • & = AND
     • | = OR
     • ^ = OR
     • << = left shift
     • >> = right shift
   • Assignment Operators and Expressions
     • =
   • Conditional Expressions
     • The first condition is evaluated, if it is true, it is executed, otherwise it goes to the next condition or to the next instruction.
