Pascal Language: Understanding the Case Structure
The case statement in Pascal allows for the selection of a code block based on the value of an expression. It provides a way to streamline conditional branching and can be particularly useful when dealing with multiple possible values for a variable.
Here's the basic syntax for a case statement in Pascal:
case expression of
// code block for value1
// code block for value2
// more value cases as needed
// default code block
In this structure, the expression is evaluated, and the corresponding code block for the matching value is executed. If none of the specified values match the expression, the code within the
else block, if present, is executed as the default case.
It's important to note that each code block is enclosed within
end statements to define the scope of the code to be executed for each value.
Overall, the case statement in Pascal provides a clean and efficient way to handle multiple conditional branches based on the value of an expression.
