- Explain why it may sometimes be useful for a function to have side effects.True or False 1-int fx(char x) is a function with int return value 2-int fx(char &x) is a function with parameter passed by value 3-void fx(char ch) is a function with no return value 4-char fx( int x) is a function with int return valueHow can we provide a function an argument by reference rather than by value?
- Match the following function with a possible asymptotic notation. I've tried to start it, but I need a little help. Thank you. What is the difference between a function argument and a function parameter? Group of answer choices An argument is a variable that is created in a function to hold a value that has been sent to it and a parameter value is the value that a function returns to the calling routine. An argument is a value that is passed into a function and a parameter is variable that the function defines to hold value of the argument. An argument is a value that is passed into a function and a parameter is the value that a function returns to the calling routine. A parameter is a value that is passed into a function and an argument is the value that a function returns to the calling routine.Only the function in which they are defined knows about local variables. Only the function in which they are defined knows about local variables. False or True More than one value may be returned by any kind of function. More than one value may be returned by any kind of function. True or false?
- Explain why it's okay for a function to have side effects on occasion.Write a function that takes three integers namely a, b, and c as parameters. The function should return the minimum difference between any two of those. (Example: a:5 b:3 c:9 function returns 2)Functions can be thought of as miniature (sub )programs inside other programs. Like any other program, we can think of functions as having inputand output to communicate with the main program.a) How does a program provide "input" to one of its functions?b) How does a function provide "output" to the program?
