Question

Which type of parameter is passed in a function for faster execution

• A. call by value
• B. call by address
• C. call by name
• D. call by string

Answer 1

The correct option is A call by value

Call by value type of parameter is passed in a function for faster execution.

The call by value method of passing arguments to a function copies the actual value of an argument into the formal parameter of the function. In this case, changes made to the parameter inside the function have no effect on the argument. By default, C programming uses call by value to pass arguments.
