Cpp program to check a number is even or odd using function
Cpp program to check a number is even or odd using function
In this tutorial, we will discuss the Cpp program to check a number is even or odd using function
In this program, we are going to learn about how to find the odd or even number from given number using function in Cpp language
First, we must understand what is even or odd?
What is Even or Odd
When the number is divided by 2 and the balance becomes zero. the above number is called as the even number – eg 2,4,6,8,10
and on the other sides when it is divided by 2 and balance becomes 1 they are called odd numbers or uneven numbers
In my previous post, I have explained the various ways to check whether the number is even or odd in c++ language
However, in this program, we embed the logic of the program to check even or odd numbers in the function
you can embed the logic of the program to check even or odd numbers using any of the following approaches in the function
Once This program received the number it will check the given number either odd or even.
After receiving the input from the user, it is stored in the variable of num. then program divides the value of num into 2 and displays the output
Check a number is even or odd using modular operator
Program 1
#include <iostream>
#include <conio.h>
using namespace std;
int find_Oddeven(int);//function prototype
int main()
{
int num;
cout << "Enter a number to ceck odd or even" << endl;
cin>>num;//get input from user
find_Oddeven(num);//calling the function
getch();
return 0;
}
//create function
int find_Oddeven(int num){//function definition
if(num%2==0)
cout<<num<<"is an even";
else
cout<<num<<"is an odd";
}
When the above code is executed, it produces the following results
Case 1
Enter a number to check odd or even 44 44 is an even
Case 2
Enter a number to check odd or even 27 27 is an odd
Program 2
Check a number is even or odd using the function with return
#include <iostream>
#include <conio.h>
using namespace std;
int find_Oddeven(int);//function prototype
int main()
{
int num;
cout << "Enter a number to check odd or even" << endl;
cin>>num;
if(num%2==0)
cout<<num<<"is an even";
else
cout<<num<<"is an odd";
find_Oddeven(num);
getch();
return 0;
}
//create function
int find_Oddeven(int num){//function definition
return(num%2==0);//return the value
}
When the above code is executed, it produces the following results
Case 1
Enter a number to check odd or even 87 87 is an odd
Case 2
Enter a number to check odd or even 20 20 is an even
Check a number is even or odd using the function with bitwise operator
#include <iostream>
#include <conio.h>
using namespace std;
int find_Oddeven(int);//function prototype
int main()
{
int num;
cout << "Enter a number to ceck odd or even" << endl;
cin>>num;//get input from user
find_Oddeven(num);//calling the function
getch();
return 0;
}
//create function
int find_Oddeven(int num){//function definition
if(num&1)
cout<<num<<"is an odd";
else
cout<<num<<"is an even";
}
Case 1
Enter a number to check odd or even 786 786 is an even
Case 2
Enter a number to check odd or even 89 89 is an odd
Check a number is even or odd using the function with conditional operator
#include <iostream>
#include <conio.h>
using namespace std;
int find_Oddeven(int);//function prototype
int main()
{
int num;
cout << "Enter a number to check odd or even" << endl;
cin>>num;//get input from user
find_Oddeven(num);//calling the function
getch();
return 0;
}
int find_Oddeven(int num){//function definition
(num%2==0) ? cout<<num<<"is an even":
cout<<num<<"is an odd";
}
When the above code is executed, it produces the following results
Case 1
Enter a number to check odd or even 101 101 is an odd
Case 2
Enter a number to check odd or even 112 112 is an even
Check a number is even or odd using the function with division operator
#include <iostream>
#include <conio.h>
using namespace std;
int find_Oddeven(int);//function prototype
int main()
{
int num; cout << "Enter a number to check odd or even" << endl;
cin>>num;//get input from user
find_Oddeven(num);//call the function
getch();
return 0;
}
int find_Oddeven(int num){//function definition
if((num/2)*2==num)
cout<<num<<" is an even ";
else
cout<<num<<" is an odd ";
}
When the above code is executed, it produces the following results
Case 1
Enter a number to check odd or even 789 789 is an odd
Case 2
Enter a number to check odd or even 118 118 is an even
Check a number is even or odd using the function with shift operator
#include <iostream>
#include <conio.h>
using namespace std;
int find_Oddeven(int);//function prototype
int main()
{
int num; cout << "Enter a number to ceck odd or even" << endl;
cin>>num;//get input from user
find_Oddeven(num);//calling the function
getch();
return 0;
}
//create function
int find_Oddeven(int num){//function definition
if(((num>>1)<<1)==num ){
cout<<num<<"is even ";
} else{
cout<<num<<"is odd";
}
}
When the above code is executed, it produces the following results
Case 1
Enter a number to check odd or even 987 987 is odd
Case 2
Enter a number to check odd or even 456 456 is even
