Lesson26and27

If you’re looking to sharpen up your C++ programming skills, then you’re in the right place. You will start with learning about dynamic memory allocation, how to create classes, and constructors. 

In the latter half of the course, inheritance, functions, I/O, exception handling, and more. Throughout the course, you will study over 90 carefully designed examples aimed to enhance your understanding of the C++ language.  

By the time you finish this course, you will be able to use more advanced functionality in your C++ programs.

C++ Programming for Experienced Engineers

## Problem		                        

Write a program that creates a `jagged 2D` array of `3` rows dynamically. The _number of columns in three rows_ should be `4`, `2`, and `5` respectively. Fill the array with random numbers and then free the jagged array.

## Sample runs

```txt
First run:

2       4       1       4
9       4
6       9       4       6       0

Second run:

3       4       0       4
9       4
5       6       5       1       1
```
