 POWER OPERATOR (**) IN PASCAL PROGRAMMING

In other to write x raised to the power of y in Pascal, the expression will be x**y, while 5 raised to the power of 2 will be 5**2.

Two asterisks (**) represents power operator in Pascal. However, the (**) will show error that “method overloading is not created”, as such, if you want to use the power operator you need to call uses math; above the var keyword. uses math; is a math library in Pascal, that allows you to access and utilize mathematical functions.

Lets demonstrate this with simple examples.

Lab1:

//pascal program to display the result of 5^2

program lab1;

uses math;

begin

writeln('The answer is::');

writeln(5**2);     

end.

 

Lab2:

{ pascal program to display the result of an initialized variable using integer datatype

}

program lab2;

uses math;

var

a : integer = 3;

b : integer = 5;

begin

writeln('The answer is::');

writeln(a**b);     

end.

 

 

Lab3:

{ pascal program to display the result of an initialized variable using real datatype and formatting the output to two decimal places

}

program lab3;

uses math;

var

m : real = 1.863;

n : real = 2;

begin

//format the output to two decimal places

writeln('The answer is::');

writeln((m**n) : 0:2);     

end.

   DATA STRUCTURE WITH C++ PROGRAMMING USING STACK PREREQUISITES TO IMPLEMENTING STACK IN C++ We will need to understand how to use some of the constructs in C++ that makes up the implementation of stack in C++ against. And this concepts will also help you in developing other codes and to debug or understand the C++ codes in a company's code bank or to interpret a boiler plate code (a ready made code). Some of these constructs or concepts are: 1. sizeof() 2. Function 3. Pointer 4. Function Pointer 5. Arrow operator 6. malloc() 7. typedef 8. struct PHASE 1: sizeof() It is used to determine the size of variables used in a program, it can determine the size of primitive (or predefined) datatype too and for any user-defined datatypes. It is an inbuilt keyword and a compile-time operator. syntax-1 using variable sizeof(variableName); syntax-2 using primitive datatype sizeof(datatype); //code implementation #include<iostream> using namespace std; int main(){ //declare v...

 CGPA CALCULATOR & BASIC HTML WEB DEV PROJECT Introduction: In this cgpa calculator, user will enter the gp for each semester, then click on the submit button to see the cgpa user can also click the reset button to begin a new input for calculation In this mini project we will be using HTML CSS JAVASCRIPT to develop a cgpa calculator NB:   With a querySelector statement, you can select an element based on a CSS selector. This means you can select elements by ID, class, or any other type of selector. Using the getElementById method, you can only select an element by its ID. Generally, you should opt for the selector that most clearly gets the job done. PHASE 1a:  PROTOTYPE (final product) PHASE 1b:  PROTOTYPE (rought sketch) Let's sketch with our hand how the cgpa calculator will look like PHASE 2: Html (for structuring the webpage content) Shortcut for div and class for css: type dot followed by the name you want e.g .cgpatitle Shortcut for div and id f...
