Program To Check Whether The Number Entered Is Positive, Negative or Zero

Program:

 #include <iostream>  
 using namespace std;  
 int main(){  
      int num;  
      cout<<"Enter the number to check: ";  
      cin>>num;  
      if(num>0){  
           cout<<"Number "<<num<<" is positive!"<<endl;  
      }else if(num<0){  
           cout<<"Number "<<num<<" is negative!"<<endl;  
      }else{  
           cout<<"Number is zero!"<<endl;  
      }  
      return 0;  
 }  

Output:

 In Case Of Negative Number:

In Case Of Positive Number:

In Case Of Zero:

Working Of The Program:

The working of the program is as follows:

2. The program starts by including the necessary header files for input/output operations.
3. The main function starts by declaring an integer variable num.
4. It then prompts the user to enter a number using cout and cin statements.
5. The user input is stored in the num variable.
6. The program checks if the value of num is greater than 0 using an if statement.
7. If num is greater than 0, it prints a message to the console saying that the number is positive using cout statement.
8. If num is less than 0, the program checks the next condition using an else if statement.
9. If num is less than 0, it prints a message to the console saying that the number is negative using cout statement.
10. If both conditions fail, the program prints a message to the console saying that the number is 0 using cout statement.
11. Finally, the main function returns 0, indicating successful execution of the program.
