Program/Source Code:
The source code to demonstrate the local and global variables is given below. The given program is compiled and executed successfully.
Output:
Explanation:
In the above program, we created a global variable $NUM initialized with value 10. After that we created the local variable $NUM initialized with 20 inside the function test_fun(). And then printed the value of the local variable inside the function test_fun(). After that, we used the global keyword to access the value of the global variable $NUM, and then we printed the value of the global variable on the webpage.
