suresh Visual Basic Interview Question: What is the difference between ByVal and ByRef in Visual Basic?
In Visual Basic, the difference between ByVal and ByRef lies in how arguments are passed to a procedure.
ByVal: When a parameter is passed by value (ByVal), a copy of the original value is passed to the procedure. This means that any changes made to the parameter within the procedure will not affect the original value outside of the procedure.
ByRef: When a parameter is passed by reference (ByRef), the memory address of the original value is passed to the procedure. This allows the procedure to directly modify the original value outside of the procedure. Any changes made to the parameter within the procedure will be reflected in the original value.
Understanding the difference between ByVal and ByRef in Visual Basic is crucial for effective programming and ensuring the desired outcome of your code.
When answering the Visual Basic interview question about the difference between ByVal and ByRef, it is important to showcase your knowledge of how parameters are passed and manipulated in Visual Basic programming.
