What should be passed in parameters when function does not require any parameters? It should return a scalar result. What is the order of evaluation of parameters - left-to-right or right-to-left? Functions in C language can be invoked in two different ways: Call by value: as explained, values of actual parameters are copied to the function’s formal parameter, and these two different types of parameters are stored in two separate memory locations. We would like a route parameter to always be constrained by a given regular expression, we can use the pattern method. 1. It means that while calling a method, parameters passed to the callee method will be clones of original parameters. A - Using args B - using scalar@_ C - Both of the above.
