- That's because of this part of the code:
- ```
- Book(string aTitle, string aAuthor, int aPages){
- aTitle = title;
- aAuthor = author;
- aPages = pages;
- }
- ```
- You're attibuting the properties from the class to the function parameter values. As the properties aren't initialized yet, they're getting just random values. It should have been the oposite. Like this:
- ```
Book(string aTitle, string aAuthor, int aPages){- title = aTitle;
- author = aAuthor;
- pages = aPages;
- }
- ```
- That's because of this part of the code:
- ```
- Book(string aTitle, string aAuthor, int aPages){
- aTitle = title;
- aAuthor = author;
- aPages = pages;
- }
- ```
- You're attibuting the properties from the class to the function parameter values. As the properties aren't initialized yet, they're getting just random values. It should have been the oposite. Like this:
- ```
- Book(string aTitle, string aAuthor, int aPages) {
- title = aTitle;
- author = aAuthor;
- pages = aPages;
- }
- ```
- you can also use member initializer syntax:
- ```
- Book(string aTitle, string aAuthor, int aPages) : title(aTitle), author(aAuthor), pages(aPages) {
- }
- ```
- or like this:
- ```
- Book(string aTitle, string aAuthor, int aPages) : title{aTitle}, author{aAuthor}, pages{aPages} {
- }
- ```
