C++ | Beginning of Arrays | Lecture 7

Lecture 7:

Today we 'll discuss about Arrays in C++.
Array is a data structure, which allows us to collect same size and type of values in single variable. And if you need to call any specific value within array. You need to call its position. Here you will learn that how can we play will array in C++.

C++ | Return Value in Function | Lecture 6

Lecture # 6:

Here you will learn that how to return value in function in C++ programming?
It is a very useful way and important way. You will use it in your programming many times. It works with user define functions. Let's try it.
Here we take dog year example.

C++ | Arguments In Functions | Lecture 5

Default arguments in functions allow you to call specific arguments within the specific function.
Here we defined two functions.

pow() And rand()

And we use them to get the specific value.
