BASIC-256 Language and Its Syntax

 

BASIC-256 is a simple version of the BASIC programming language designed for beginners. It provides a straightforward syntax that makes it easy for students and new programmers to learn programming concepts without getting overwhelmed by complex syntax rules.

Key Features of BASIC-256:

• Simple Syntax: The language uses straightforward commands that are easy to understand and remember.

• Graphics Support: BASIC-256 includes simple graphics capabilities, allowing users to draw shapes and create graphical applications.

• Sound Support: It supports sound generation, enabling the creation of multimedia applications.

• Built-in Editor and IDE: BASIC-256 provides an integrated development environment (IDE) that includes a code editor and tools for running and debugging programs.

• Cross-Platform: It is available for Windows, Linux, and macOS, making it accessible to a wide range of users.

Basic Syntax

Here are some fundamental components of the BASIC-256 syntax:

• Variables: Declared without data types.
  
  
• Operators: Standard arithmetic (+, -, *, /, ^) and comparison operators (=, <>, <, >, <=, >=).
  
  
• Loops: for, while, and repeat-until loops for iteration.
  
  
• Conditionals: if, then, else, elseif for decision-making.
  
  
• Input/Output: print and input for displaying output and reading user input.

To display the first $\mathrm{ natural\; numbers\; using\; a<span\; style="display:\; inline\; !important;">for\; loop\; in\; BASIC-256,\; we\; can\; use\; the\; following\; code:</span>}$

' Program to display the first n natural numbers

    input "Enter the number of natural numbers to display: ", n

    for i = 1 to n
        print i
    next i

Explanation:

1. Input: The program starts by asking the user to input the number $n$, which represents how many natural numbers we want to display.

2. For Loop: The for loop is used to iterate from 1 to $n$. The variable i acts as a counter, and in each iteration, its value is printed.

3. Output: The print statement is used to display the current value of i, which corresponds to the natural number in the current iteration.

## 1. This is a simple calculator program that performs basic arithmetic operations based on user input

input "Enter first number: ", num1

input "Enter second number: ", num2

print "Choose an operation (+, -, *, /): "
input operation$

if operation$ = "+" then
     result = num1 + num2

elseif operation$ = "-" then
     result = num1 - num2

elseif operation$ = "*" then
     result = num1 * num2

elseif operation$ = "/" then
     if num2 <> 0 then
         result = num1 / num2
     else
         print "Cannot divide by zero!"
     end if

else
     print "Invalid operation!"
end if

print "Result: ", result

## 2.  This program checks whether a given number is a prime number 

input "Enter a number to check if it is prime: ", num

    is_prime = true

if num <= 1 then
     is_prime = false
else
 for i = 2 to num / 2
     if num mod i = 0 then
         is_prime = false
         exit
     end if
 next i
end if

if is_prime then
     print num, " is a prime number."
else
     print num, " is not a prime number."
end if

## 3. This program generates the first n numbers of the Fibonacci series.

input "Enter how many fibonacci number you want to display  : ", n 

    a = 0 

    b = 1 

 print "Fibonacci Series: " 

    print a 

    print b 

 for i = 3 to n 

     c = a + b 

     print c 

     a = b 

     b = c 

next i

## 4. This program draws a simple house with a roof, door, and windows using graphics commands.
