- Which among the following function can be called without arguments? i) void add(int x, int y=0) ii) void add(int=0) iii) void add(int x=0, int y=0) iv) void add(char c)using void functions 1. Complete the program shown below. Note: do not omit the comments a) You will write a void function to get a positive integer between 1 and 12 inclusive. The twelve numbers represent the months of the year. The user will be asked to enter an integer between 1 and 12 inclusive. If the number entered by the user is not within range, an appropriate error message will be displayed, and the user will be asked to try again until a valid number is entered. b) You will write a void function to print the month number and the month name with an appropriate message. Consider a good layout when displaying the output. c) You will also complete the function main by making a call to the function GetMonthNumber with an appropriate argument and by making a call to the function DisplayMonth with an appropriate argument d) Add a loop to allow the program to repeat, allowing the user to continue. Consider proper indentation and alignment of the statements. e) Output your name as…void fx(char ch) is a function with no return value int fx(char x) is a function with int return value int fx(char &x) is a function with parameter passed by value char fx( int x) is a function with int return value
- 3- It is not possible to change the value of the pointer. (True or False). 4- If the following lines of code have errors, correct them; otherwise, write "no errors." for (int i=2; i<5; i++) { int s=1*2; } cout << s; 5- A function cannot be called from inside another function. (True or False). 6- How to make a function return multiple values? 7- Every class member is by default. (public, private, not public nor private) 8- Create an instance of the following class and call its methods. class Exam{ int grade; public: void seta (int b) (grade=b; } int geta () {return grade; } 9- When the word const is put before the variable definition, what does that mean? 10- How to concatenate two strings in C++ language? C++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)task1: write a void function divisor that receives an integer number and display its divisor on screen including 1 and itself. write the main function to test your function. task2: You are required to create a conversion program. First ask the user his choice and then convert. • Conversion from Pound to Kg. (1 Pound = 0.453 Kg) • Conversion from Feet to centimeter (1 Foot = 30.48 cm) • Convert Hours & minutes in Days
- The following function has errors. Locate as many errors as you can. void getValue(int value&) { cout << "Enter a value: "; cin >> value&;}3.What function will be called with the independent syntax “test(5,6,7);”?a) void test(int x, int y)b) void test(int x=0, int y, int z)c) int test(int x=0, y=0, z=0)d) void test(int x, int y, int z=0)Why would you want to use a return statement in a void function, you may wonder.
