Final answer:
It is acceptable to mix normal variables and pointer variables in the same function declaration to provide flexibility and efficiency in a function's design.
Step-by-step explanation:
Yes, it is perfectly acceptable to have both normal variables and pointer variables as parameters in the same function declaration. In programming, particularly in languages like C and C++, functions often require different types of parameters to perform various tasks.
A normal variable is passed by value, meaning the function receives a copy of the variable, whereas a pointer variable is passed by reference, allowing the function to manipulate the original data.
This combination can provide flexibility and efficiency in a function's design. For instance, a function can receive a data array to process via a pointer, and its size as a normal variable.
