At times you might want a variable to have a value other than the default as soon as the variable is declared. X++ allows you to initialize variables in the declaration by adding an assignment statement:
// Assigns value of pi to 12 significant digits real pi = 3.14159265359;
Another syntax is needed to initialize objects because they are initialized by invoking the new method on the class:
// Simple call to the new method in the Access class
Access accessObject = new Access();
Multiple Declarations
X++ allows you to declare more than one variable in the same declaration statement. For example:
// Declares 2 integers, p and q int p,q;
// Declares array with 100 integers with 5 in memory and k as integer with value 1
int a[100,5], k=1;
X++ follows the naming conventions of the .NET framework
X++ follows the naming conventions of the .NET framework, which means that variable names must begin with a letter or an underscore, and can contain letters, numbers, and underscores. They should also be descriptive and meaningful, using camelCase notation. For example, "myVariable" is a valid variable name, but "my_variable" is not.
It's also worth noting that, X++ has some reserved keywords that cannot be used as variable names, for example, keywords such as "class", "int", "new", "while" etc.
Additionally, it's a good practice to use meaningful and descriptive variable names, that indicate the purpose of the variable, this will help you to maintain and understand your code better. Also, it's important to follow a consistent naming convention throughout your codebase, this will make it easier for other developers to understand and work with your code.
