Division of two floating point numbers using pointer in C++

Division of two floating point numbers using pointer in C++

In this tutorial, we will discuss the concept of Division of two floating point numbers using pointer in C++

In this topic, we are going to learn how to divide two floating point numbers using pointer in C++ programming language

What is division

The division is a method of splitting a group of things into equal parts. The division is an arithmetic operation inverse of multiplication

It is one of the four basic operation of arithmetic calculation others being addition,subtraction,multiplication

The division of two natural numbers means it is the operation of calculating the number of times one number is contained within one another

 

C++ exercise to Divide two floating point numbers

Program to division of two floating point numbers using pointer

Program 1

In this program, the user initialize two floating point  numbers using two variables and then the program calculates the division of the given numbers using the pointer in C++ programming language

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    float num1=30.0,num2=2.2;
//Declare and initialize float variables
    float *ptr1,*ptr2;
//Declare float pointer variables
    ptr1=&num1;
 //Assign the address of num1 to ptr1
    ptr2=&num2;
 //Assign the address of num2 to ptr2
    float div=(float)*ptr1/ *ptr2;
//float division
    cout<<"Division is: "<<div;
//display result on the screen
    getch();
    return 0;
}

When the above code is executed, it produces the following result

Division is: 13.6364

 

Program to division of two floating point numbers using pointer – Entered by user

Program 2

The program allows the user to enter two floating point numbers and then it calculates the division of the given numbers using the pointer in C++ programming language

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    double num1,num2,div;
    //Declara double variables
    double *ptr1,*ptr2;
    //declara double pointers
    cout<<"Please enter the two float numbers\n";
    //Ask input from the user
    cin>>num1>>num2;
    //Reading the input from the user
    ptr1=&num1;
    //Assign the address of num1 to ptr1
    ptr2=&num2;
     //Assign the address of num2 to ptr2
    div=(double)*ptr1/ *ptr2;
    //Division of two floats
    cout<<"Division is: "<<div;
    //Display result on the screen
    getch();
    return 0;
}

When the above code is executed, it produces the following result

Please enter the two float numbers
45.00
12.00
Division is: 3.75
