Calculate division of two floating point numbers using pointer in C

Calculate division of two floating point numbers using pointer in C

In this tutorial, we will discuss the concept of Calculate 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 float variables and then the program calculates the division of the given numbers using the pointer in C programming language

#include <stdio.h>
#include <stdlib.h>

int main()
{
    float num1=33.33,num2=11.11,div;
//Declare and initialize two float variables 
    float *ptr1,*ptr2;
//Declare two float pointer variables
    ptr1=&num1;
//Assign the address of num1 to ptr1
    ptr2=&num2;
//Assign the address of num2 to ptr2
    div=(float)*ptr1/ *ptr2;
//Calculate float division
    printf("Division is: %.2f",div);
//Display result on the screen
    getch();
    return 0;
}

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

division is: 3.00

 

Program to division of two 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 <stdio.h>
#include <stdlib.h>

int main()
{
    double num1,num2,div;
//Declare double variables
    double *ptr1,*ptr2;
//Declare double pointer variables
    printf("Please enter the two float numbers\n");
//Ask input two float numbers from user
    scanf("%lf %lf",&num1,&num2);
//Reading the float numbers from user

    ptr1=&num1;
//Assign the address of num1 to ptr1
    ptr2=&num2;
//Assign the address of num1 to ptr2
    div=(float)*ptr1/ *ptr2;
//Calculate float division
    printf("Division is: %.2lf",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
4.5
0.5
Division is: 9.00
