Negative Number
Explanation :
  • If the user inputs a number greater than or equal to 0, the condition x >= 0 is true, and the program prints "Positive Number".
  • If the user inputs a negative number, the condition x >= 0 is false, and the program executes the code block following the else statement, printing "Negative Number".
This code provides a simple and concise way to determine whether a number is positive or negative.
