Division of two numbers without using divisional operator in C++

Division of two numbers without using divisional operator in C++

In this tutorial, we will discuss the concept of Division of two numbers without using divisional operator in C++

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

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

Program 1

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


int division(int,int);   //function prototype / declaration
int main()
{
    int num1,num2,a,b,counter=0;//Variable declaration and initialization
    cout<<"Enter two number to find division\n";
//Ask input from the user
    cin>>a>>b;  //numbers receive from the user

   num1=a;//Assign the value of a to num1
   num2=b;//Assign the value of b to num2
   while(num1>=num2)
   {
       num1=num1-num2;
       counter++;
   }

     cout << "Division of "<<a<<" and "<<num2<<" is: " << counter<<endl;
    getch();
    return 0;
}

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

Enter two numbers to find division:
450
25
Division of 450 and 25 is: 18

Program to divide two numbers – Entered by user

Program 2

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

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


int division(int,int);   //function prototype / declaration
int main()
{
    int num1,num2,a,b,result=0;
    cout<<"Enter two number to find division\n";
    cin>>a>>b;  //numbers receive from the user

   num1=a;
   num2=b;
   /*
   while(num1>=num2)
   {
       num1=num1-num2;
       counter++;
   }*/int div=num1+num2;
while(div>num2){
        div=div-num2;
result++;
}
     cout << "Division of "<<a<<" and "<<num2<<" is: " << result<<endl;
    getch();
    return 0;
}

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

Enter two numbers to find division:
120
6
Division of 120 and 6 is: 20
