Program To Check If The Number Is Even Or Not

Program:

 #include <iostream>    
 using namespace std;    
 int main() {  
      int num;  
      cout<<"Enter the number to check: ";  
      cin>>num;  
      if(num%2 == 0){  
           cout<<"The number "<<num<<" is even!"<<endl;  
      }else{  
           cout<<"The number "<<num<<" is not even!"<<endl;  
      }  
      return 0;    
 }   

Output:

In Case Of Even Number:

In Case Of Non-Even Number:

Working Of The Program:

1. Then, I prompt the user to enter a number to check whether it is even or not using cout. 2. I read in the user input using cin and store it in the variable num. 3. I check if the number is even using an if-else statement and the modulo operator %. 4. If the remainder of num divided by 2 is 0, then num is even. 5. In that case, I print out a message using cout that says "The number [num] is even!", where [num] is replaced with the value of num. 6. If the remainder of num divided by 2 is not 0, then num is odd. 7. In that case, I print out a message using cout that says "The number [num] is not even!", where [num] is replaced with the value of num. 8. Finally, I return 0 to indicate that the program has completed successfully.
