- Under what circumstances can you successfully return a pointer from a function?pointers as Arguments:In the C programming language there is no pass-by-reference syntax to passa variable by reference to a function. Instead a variable is passed by pointer(just to be confusing, sometimes passing by pointer is referred to as pass byreference). This Practice Program asks you to do the same thing as C.Here is the header for a function that takes as input a pointer to an integer:1. void addOne (int ∗ptrNum )Complete the function so it adds one to the integer referenced by ptrNum.Write a main function where an integer variable is defined, give it an initialvalue, call addOne, and output the variable. It should be incremented by 1.Define the term " pointer to void " .
- Task related to pointers : Write a c++ program that asks the user to enter integers as inputs to be stored in the variables 'a' and 'b' respectively. There are also two integer pointers named ptrA and ptrB. Assign the values of 'a' and 'b' to ptrA and ptrB respectively, and display them. ( Drop code in words , explain the code and drop the screenshot of output as well )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++c++ How do you declare a pointer that will hold an integer type?. Multiple choice. int *p; int &p; int p; int* p;
- Month Day Calculator in C Using basic concepts of Pointers and Structures (Pointers and Multi-dimensional arrays), create a C program that calculates the month's day from a given year and year's day. Use pointers for the month and month's day variables. Don't forget to add proper errors handling in your program. - Follow the instructions below for handling error. - Invalid Input- Invalid year- Invalid year day Modify the provided monthAndDay.c class file to receive the parameters in the way and also print the proper formatted output. Example: # ./month_day <year> <yearday> # Example for Feb 2nd, 2019:\$ ./month-day 2019 33Feb 02, 2019 class- monthAndDay.c - #include <stdio.h> /* monthAndDay function's prototype*/void monthAndDay(int year, int yearday, int *pmonth, int *pday); int main() {return 0;}Describe Operations on Pointer Variables.Consider the following pseudo code, Method func() { PRINT “This is recursive function" func() } Method main( { func() } What will happen when the above snippet is executed?
- Using C++ Programming language: Assume you want a function which expects as parameters an array of doubles and the size of the array. Write the function header that accepts these parameters but is defined in such a way that the array cannot be modified in the function. You can use your own variable names for the parameters.Variables can be passed to a function by Select one: a.reference b.all (pointer, value, and reference) c.value d.pointer2- In C++ language, every line of code must end with a semicolon. (True or False). 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=i*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?
