C++ program: Divide two numbers without using arithmetic operator

C++ program: Divide two numbers without using arithmetic operator

In this tutorial, we will discuss the concept of C++ program: Divide two numbers without using arithmetic operator

In this topic, we are going to learn how to divide two numbers without using Arithmetic operator 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 numbers

Program to division of two numbers without using division operator

The program allows the user to enter two integer numbers and then it calculates the division of the given numbers without using the division operator in C++ language

Program 1

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

int main()
{
    int num1,num2,result=0;//variable declaration
    // from the user - input from keyboard
    cout<<"Enter two number for input: ";
    cin>>num1>>num2;//Reading the input for num1 and num2
     while(num1>=num2) {
            num1=num1-num2;
     result++;
     }
     cout<<"Division is: "<<result;
     getch();
     return 0;
}

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

Enter two numbers for input: 2400
80
Division is: 30

 

Program to division of two numbers with using Bitwise operator

The program allows the user to enter two integer numbers and then it calculates the division of the given numbers using with the Bitwise operator in C++ language

Program 2

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

int division(int,int);//function prototype
int main()
{
    int num1,num2;
    //Variable declaration and initialization
    cout<<"Enter two numbers \n";
    //Ask input from the user
    cin>>num1>>num2;
    //Reading the input from the user
    int div=division(num1,num2);//Calling the function
    cout<<"Division of given two numbers is: "<<div;
getch();
    return 0;
}

int division(int num1,int num2){//function definision
    int temp=1,result=0;
    while(num2<=num1) {//Using while loop
num2<<=1;
temp<<=1;

}
while(temp>1)
{
    num2>>=1;
temp>>=1;
if(num1>=num2)
{
    num1-=num2;
     result+=temp;
}
}
return result;
}

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

Enter two numbers
45
9
Division of given two numbers is: 5
