- A variable declared in the body of a function is said to be what to that function? Group of answer choices Local Adjacent Global Integrated DefinedIn C++ programming lanuage: Normally a function does not have access to a variable defined in another function. However, by using a ________________variable as a parameter, a function may change a variable that is defined in another function.To accomplish pass-by-reference when passing a nonarray variable to a function, it’snecessary to pass the__________________ of the variable to the function.
- Create a function named fnTuition that calculates the tuition for a student. This function accepts one parameter, the student ID, and it calls the fnStudentUnits function that you created in task 2. The tuition value for the student calculated according to the following pseudocode: if (student does not exist) or (student units = 0) tuition = 0 else if (student units >= 9) tuition = (full time cost) + (student units) * (per unit cost) else tuition = (part time cost) + (student units) * (per unit cost) Retrieve values of FullTimeCost, PartTimeCost, and PerUnitCost from table Tuition. If there is no student with the ID passed to the function, the function should return -1. Code two tests: 1) a student who has < 9 student units, and 2) for a student who has >= 9 student units. For each test, display StudentID and the result returned by the function. Also, run supportive SELECT query or queries that prove the results to be correct.please code in python A local variable in a function is either a parameter or a variable which appears on the left hand side (LHS) of an assignment statement in the function. A variable in a function is global if it is not local, but if you want to assign something to a global variable, g, in a function, then you will need the statement global g. Without the global g statement, assignment, like, g = 5, would make g local. You shouldn't use global variables very often when writing functions, since global variables reduce readability. Occasionally they are useful, such as when you would like to count how often a function is called. Define a global variable, countcalls, and increment it inside the power(x, n) function that you wrote for Q4, so that it counts the number of times the power function is called. Show that it produces the expected number of calls for power(2, 10) and power(5, 10) and power(5, 0), each separatelyIn the following code segment, the variable p is stored in the heap of the virtual address space of the program. int main() { double x; int *p = new int; return 0; %3D } OTrue OFalse
- Write a function called substring that uses the leftmatch and rightmatch functions to remove a pattern from the left and right side of a value. It should take three arguments as shown: $ substring /usr/ /usr/spool/uucppublic /uucppublic spool $ substring s. s.main.c .c main $ substring s. s.main.c .o Only left match main.c $ substring x. s.main.c .o No matches s. main.cWhich of the following are benefits of specifying a function's parameters' data type(s)? Choose all that apply. it constructs data of the correct type in the parameter O it conveys the valid types of argument expressions required in a call to the function O it conveys valid operations on parameters within the function's body O it ensures a default value for the parameter when an argument is missing it makes it possible to identify invalid function calls without running the program there are no benefits in specifying a function's parameters' data typesWrite a split_check function that returns the amount that each diner must pay to cover the cost of the meal. The function has four parameters: . bill: The amount of the bill. people: The number of diners to split the bill between. tax_percentage: The extra tax percentage to add to the bill. tip_percentage: The extra tip percentage to add to the bill. ● ● The tax or tip percentages are optional and may not be given when calling split_check. Use default parameter values of 0.15 (15%) for tip_percentage, and 0.09 (9%) for tax_percentage. Assume that the tip is calculated from the amount of the bill before tax. Sample output with inputs: 25 2 Cost per diner: $15.50 Sample output with inputs: 100 2 0.075 0.21 Cost per diner: $64.25 Learn how our autograder works 461710.3116374.qx3zqy7 1 # FIXME: Write the split_check function.

- When used inside a function with a parameter, an asterisk groups a variable number of positional arguments into a single _________________ of parameter values.When invoking a function that takes a significant number of arguments, the order in which those parameters are sent in is quite important.C++ If you pass a variable by ________________ to a function, the function will make a local copy of that variable and use that copy throughout the function’s execution. Changes to the parameter are not made to the argument.
