继承可以理解为一个类从另一个类获取成员变量和成员函数的过程。
语法：
class 派生类名:［继承方式］基类名
{
派生类新增加的成员
};
被继承的类称为基类或父类，继承的类称为派生类或子类。
继承和派生是一个概念，只是站的角度不同。
派生类除了拥有基类的成员，还可以定义新的成员，以增强其功能。
使用继承的场景：
如果新创建的类与现有的类相似，只是多出若干成员变量或成员函数时，可以使用继承。
当需要创建多个类时，如果它们拥有很多相似的成员变量或成员函数，可以将这些类共同的成员提取出来，定义为基类，然后从基类继承。

Seems like nowadays, everybody lacks patience
Want it right now, always sick of this waiting
Hating on anyone, stuck in the process
For God sakes, how long will you waste, it's non sense
Telling you to give up on the dream, but who
Are they to throw away, all their faith in you
No way you're gonna fade, let them say and shoo
Get away, 'cause what they say don't have weight with you
You keep moving on, write that, do a song
Right track, you belong, fight back, prove them wrong
Yeah, just keep on, keeping on
Yeah, 'cause this track you be on
Right there's gotta lot of potential
So never give up, just sharpen your pencil
Close out all the negative talk
Put on those old shoes and choose where you walk
When you fall, stand up
And when you break, stand tough
And when they say, you can't
You say I can, I can
When you fall, stand up
And when you break, stand tough
And when they say, you can't
You say I can, I can
Don't lose faith, 'cause the minute you break
Is the minute you wake, with a million mistakes
And a million regrets that, you'll never get back
The time that you set back, to please other friends that
Tell you that you can't be what you wanna be
There's a world out there go and see what you wanna see
I've been there, I can relate
So let this song tell ya that it's never too late
Wide awake, and I see more than ever
That people are quick to give up on their endeavors
Never really try 'cause they're scared of failure
So, allow me to be the first to tell ya'
I've failed more times than I've succeeded
In the end, exactly what I needed
To allow me to learn the right steps
So I'd never go back, and I never regret
When you fall, stand up
And when you break, stand tough
And when they say, you can't
You say I can, I can
When you fall, stand up
And when you break, stand tough
And when they say, you can't
You say I can, I can
A lot of dreams get left at the wayside
And I can feel their death in the baseline
'Cause of something' someone once said
At once dead,
Don't let them stop you in your tracks, at once dead
Say to yourself, I'ma be stronger than
Stay up late everyday working harder than
Keep my head focused, stick to the plan
They say I can't but I say I can
When you fall, stand up
And when you break, stand tough
And when they say, you can't
You say I can, I can
When you fall, stand up
And when you break, stand tough
And when they say, you can't
You say I can, I can
