I passed my Intro to C++ exam with help
from Programiz PRO
Landan Devencia, US
I was lucky to come across Programiz PRO because it instantly changed my experience of learning to code. Programiz PRO is remarkable; it gives you all the tools you need to learn your chosen programming language.
Programiz PRO has recently been an aid in my ‘Introduction to C++’ class. In need of help, I picked up the course about C++ basics to save me in a challenging course and teach me beyond the scope of the classroom.

One of the biggest challenges when learning to code is the negative narratives that can set in when you start coding, such as
I’m stuck
I can’t do it
This is not for me
I’m not smart enough
I’m stuck
I can’t do it
This is not for me
I’m not smart enough
I’m stuck

sensAI,
your personal coding mentor, who pops up when you get error like these
SyntaxError
File "", line 35
country='Canada
^
The syntax error in the code is caused by not having a closing parenthesis after the print statement.
Fixed Code:
country = 'United States'
print(country)
country = 'Canada'
print(country)

Find the sum of two numbers
Difficulty: Easy
XP: 100
Create an interface named Polygon with an abstract method getArea().
Implement the Polygon by another class Triangle.
Inside the class, provide an implementation of the getArea() method to compute the area of the triangle.
Instructions
Inside Class
Create an interface named Polygon with an abstract method getArea().
Implement the Polygon by another class Triangle.
Inside the class, provide an implementation of the getArea() method to compute the area of the triangle.
Outside Class
Create a Main class with the main() method.
Inside the method, get two double inputs for base and height.
Call the getArea() method using the object of Dog.
Pass base and height as the arguments to getArea().
Example
For this input
12.0
