Divide two numbers in C++ language|6ways
In this tutorial, we will discuss the Divide two numbers in C++ language
In this post, we are going to learn how to find division of two numbers using different 6 ways in C++ language
Divide two numbers in C++ -using standard method
Program 1
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
int num1=100,num2=20;
int div=num1/num2;
cout << "Division of "<<num1<<" and "<<num2<<" is: " << div<<endl;
getch();
return 0;
}
When the above program is executed, it produces the following result
Division of 100 and 20 is: 5
In this program,
- Integer variable num1 and num2 both are declared and initialized
- The num1 and num2 both are divided together and the value assigned to the integer variable div
- Finally the program is displayed the output using cout<<.
Divide two numbers in C++ -using user input
Program 2
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
int num1,num2;
cout<<"Enter two numbers: ";
cin>>num1>>num2;
int div=num1/num2;
cout << "Division of "<<num1<<" and "<<num2<<" is: " << div<<endl;
getch();
return 0;
}
When the above program is executed, it produces the following result
Enter two numbers: 666 6 Division of 666 and 6 is: 111
in tis program,
- Integer variable num1 and num2 both are declared,
- The program takes input from the user
- Then the user enters the input value for num1, num2
- The program will read the input using cin>> and store the variables num1 and num2.
- The num1 and num2 both are divided together and the value assigned to the integer variable div
- Finally the program is displayed the output using cout<<
Divide two numbers in C++ -using function
Program 3
#include <iostream>
#include <conio.h>
using namespace std;
int division(int,int); //function prototype / declaration
int main()
{
int num1,num2,result;
cout<<"Enter two number to find division\n";
cin>>num1>>num2; //numbers receive from the user
result=division(num1,num2);//assign the output to variable result
//function call
cout << "Division of "<<num1<<" and "<<num2<<" is: " << result<<endl;
getch();
return 0;
}
int division(int a, int b)
{
return a/b;
}
When the above program is executed, it produces the following result
Enter two numbers: 560 70 Division of 560 and 70 is: 8
In this program
- Declare a function named as division() with two int parameters
- Declare num1,num2 and result.
- The program takes input from the user
- Then the user enters the input value for num1, num2
- The program will read the input using cin>> and store the variables in num1, num2 respectively
- Define the function (division())for find division
- Call the function to produce output
- Finally, the program displays the result of division using cout<<
Divide two numbers in C++ -using recursion
Program 4
#include <iostream>
#include <conio.h>
using namespace std;
int division(int,int); //function prototype / declaration
int main()
{
int num1,num2,result;
cout<<"Enter two number to find division\n";
cin>>num1>>num2; //numbers receive from the user
result=division(num1,num2);//assign the output to variable result
//function call
cout << "Division of "<<num1<<" and "<<num2<<" is: " << result<<endl;
getch();
return 0;
}
int division(int x, int y)
{
if (y==0)
{
return 0;
}
else if (x-y==0){
return 1;
}
else if (x<y){
return 0;
}
else{
return (1+division(x-y,y));
}
}
When the above program is executed, it produces the following result
Enter two numbers to find division: 448 16 Division of 448 and 16 is: 28
- Declare a function named as division() with two int parameters
- Declare num1,num2 and result.
- The program takes input from the user
- Then the user enters the input value for num1, num2
- The program will read the input using cin>> and store the variables in num1, num2 respectively
- Define the function (division())for find division recursively
- Call the recursive function to produce output
- Finally, the program displays the result of subtraction using cout<<
Divide two numbers in C++ -using without divisional operator
Program 5
#include <iostream>
#include <conio.h>
using namespace std;
int division(int,int); //function prototype / declaration
int main()
{
int num1,num2,a,b,counter=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++;
}
cout << "Division of "<<a<<" and "<<num2<<" is: " << counter<<endl;
getch();
return 0;
}
When the above program is executed, it produces the following result
Enter two numbers to find division: 1250 25 Division of 560 and 70 is:50
Divide two numbers in C++ -using pointer
Program 6
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
int num1,num2,*ptr1,*ptr2;
//variable declaration
cout << "Enter the first number: " << endl;
cin>>num1;//read the value for num1
cout << "Enter the second number: " << endl;
cin>>num2;//read the value for num2
ptr1=&num1;
ptr2=&num2;
int div = *ptr1/ *ptr2;//division calculation
cout <<num1 <<" is devided by "<< num2<<" is: "<<div<<endl;
getch();
return 0;
}
When the above program is executed, it produces the following result
Enter the first number: 1250 Enter the second number 25 1250 is divided by 25 is: 50
- Declare variables num1,num2 and div.
- Declare pointer variables *ptr1, *ptr2.
- The program takes input from the user
- Then the user enters the input value for num1 and num2
- The program will read the input using cin>> and store the variables in num1, num2 respectively
- Address of the variables num1 and num2 assigned to pointer variables ptr1 and ptr2 respectively
- calculate the division of the numbers using pointer variable and Assign the product value to div variable
- Finally, the program displays the result using cout<<
