pascal variable initialisation
In Pascal, variables can be initialized by assigning them a value when they are declared. Here's an example:
var
myVariable: integer = 10;
In this example, the variable myVariable
is declared as an integer and initialized with the value 10
.
You can also initialize variables later in the code using the :=
assignment operator. Here's an example:
var
myVariable: integer;
begin
myVariable := 20;
end.
In this example, the variable myVariable
is declared as an integer but not initialized at the time of declaration. It is then initialized with the value 20
inside the begin
and end
block.
It's important to note that Pascal requires variables to be initialized before they are used. If a variable is not explicitly initialized, it will have an undefined value.
