BASIC PROGRAMMING

MATHEMATICAL OPERATORS

Addition 

The computer recognizes it with the symbol +

Subtraction

The computer recognizes it with the symbol -

Multiplication

The computer recognizes it with the symbol * 

Division

The computer recognizes it with the symbol /

Mod 

The computer recognizes it with the symbol

Div

Remainder of the decimal part of a division

The computer recognizes it with the symbol //

     

Power

The computer recognizes it with the symbol **

Root

this operation cannot be symbolized so for the computer to understand we must radican power to 1 division index

((27)1/3)

HIERARCHY OF OPERATIONS

ALGORITHMIC EQUATIONS

When we program it must be understandable for the computer because of that we must organize the

operations from the smallest to the largest this in brackets

RELATIONALS OPERATIONS

the relationals operator use to compare two values

LOGICAL OPERATORS

FLOWCHART

Flowcharts use special shapes to represent different types of actions or steps in a process. Lines and arrows show the sequence of the steps, and the relationships among them. These are known as flowchart symbols.

KEYWORDS

write: this command is use to show information in screen

read:this command is use to capture information, this will save in a variable

variable: it is the way in which they categorize the data that must be saved varies based on the program and language

IF-THEN

a condition is established with relational and logical operators if it is true one action occurs otherwise another

SWITCH

this command is based on a control variable and it is value causes a series of actions in each case

REPETITIVE CYCLES

For loop

in the for loop you can indicate the maximum number of iterations

WHILE LOOP

in the while loop the idea is to repeat something if the condition is true

DO WHILE LOOP

the do while loop checks the condition at the end of the loop. this means that the statements inside the loop body will be executed at least once even if the condition is never true

ARRAYS

are fuction to store more sata in a variable,only can save info to same info
