Consider the following program: #include /* function declaration */ void function(int x, int *y, int *z); int main() { int a 100, b, c ; function (a, &b, &c); } void function(int x, int *y, int *z) { x = x + 2; *y = x - 1; *Z x + 1; } What are the final values of a, b, and c respectively? Select one: O a. (100, 101, 103 ) O b. (102, 101, 103) O c. (100, 99, 101) O d. (102, 99, 101)

In C++, Given the following function prototype: void testDefault(int a, int b = 7, char z = '*'); Indicate if each of the following function calls are valid or invalid a) testDefault(5); b) testDefault(); c) testDefault(6, '#'); d) testDefault(0, 0, '?');
Mark the following statements as true or false: a. To use a predefined function in a program, you need to know only the name of the function and how to use it. (1) b. A value-returning function returns only one value. (2, 3) c. Parameters allow you to use different values each time the function is called. (2, 7, 9) d. When a return statement executes in a user-defined function, the function immediately exits. (3, 4) e. A value-returning function returns only integer values. (4) f. A variable name cannot be passed to a value parameter. (3, 6) g. If a C++ function does not use parameters, parentheses around the empty parameter list are still required. (2, 3, 6) h. In C + + , the names of the corresponding formal and actual parameters must be the same. (3, 4, 6) i. A function that changes the value of a reference parameter also changes the value of the actual parameter. (7) j. Whenever the value of a reference parameter changes, the value of the actual parameter changes. (7) k. In C++, function definitions can be nested; that is, the definition of one function can be enclosed in the body of another function. (9) l. Using global variables in a program is a better programming style than using local variables, because extra variables can be avoided. (10) m. In a program, global constants are as dangerous as global variables. (10) n. The memory for a static variable remains allocated between function calls. (11)

When creating function definitions, it is important for a function to receive its input data via its parameters.It is almost always a bad idea for a function that performs calculations to also perform any kind of consoleinput or output. Trip Cost Function: - write a function to help a travel agent calculate the cost of a trip for a family. The tripincludes a flight and some number of nights in a hotel. The hotel sleeps at most 2 people in each room.Write a Python function that takes four parameters as input and RETURNS the total cost of the trip. Thefour parameters should be the airfare per person in dollars, the room cost per night in dollars, the numberof travellers, and the number of nights. - your function should do no console input and no console output. It must receive its inputthrough its parameters and send its output using a return value. Console I/OIn the main part of your program (i.e. NOT inside the function’s body), use console input to get the necessaryvalues needed by…
Please help me explain the following void function c++ code, which I did not understand. Especially for the first void function and int main(), I do not understand why the first void function enter the number and the int main function print out the final answer. #include <iostream>using namespace std; void getNumber(int *input); void doubleValue(int *val); int main(){ int number; getNumber(&number); doubleValue(&number); cout<<"That value doubled is"<<number<<endl; return 0;}void getNumber(int *input){ cout<<"Enter an integer number:"; cin>>*input; }void doubleValue(int *val){ *val *=2;}
Function floor can be used to round a number to a specific decimal place. The statement y = f loor ( x * 10 + .5 ) / 1 0 ; rounds x to the tenths position (the first position to the right of the decimal point). The statementy = floor ( x * 100 + .5 ) / 100 ; rounds x to the hundredths position (the second position to the right of the deci mal point). Write a program in c++ that defines four functions to round a number x in various ways:a) roundToInteger ( number )b) roundToTenths ( number )c) roundToHundredths ( numberd) roundToThousandths ( number )For each value read, your program should print the original value, the number rounded to the nearest integer, the number rounded to the nearest tenth, the number rounded to the nearest hundredth and the number rounded to the nearest thousandth.

Topic: A function with parameters passed by value and passed by reference Do not use anything beyond Chapter 6 materials. Write a C++ Write a single function rectangleAreaPerim (width, height, area, perimeter) that calculates both the area and the perimeter of a rectangle given its width and height. -Input parameters to the functions are the width and height of the rectangle. Function cannot modify the input parameters. -Output parameters of the function are the area, perimeter, and a boolean return (success or failure). -This function returns true if both width and height are not negative, and thus calculation is required. Otherwise the function returns false and skips all calculations. -The function rectangleAreaPerim(width, height, area, perimeter) should Not use any "cin" or "cout". Only the main() function will contain "cin" and "cout". -The main() function calls the function rectangleAreaPerim() in a loop until the user enters 0 0. These are "Sentinel" values that stop the…
