- 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;}IN C PROGRAMMING LANGUAGE: Please write a pointer version of strncmp() named pstr_ncmp(char *s, char *t, int n) which compares the first n characters.Given variables category, heat, and voltage, declare and assign the following pointers: character pointer categoryPointer is assigned with the address of category. integer pointer heatPointer is assigned with the address of heat. double pointer voltagePointer is assigned with the address of voltage. Ex: If the input is C 355 3.5, then the output is: Product category: COperational limit: 355 degrees at 3.5 volts. #include <iostream>#include <iomanip>using namespace std; int main() { char category; int heat; double voltage; /* Your code goes here */ cin >> category; cin >> heat; cin >> voltage; cout << "Product category: " << *categoryPointer << endl; cout << "Operational limit: " << *heatPointer << " degrees at " << fixed << setprecision(1) << *voltagePointer << " volts." << endl; return 0;}
- 1. Given the codes below. Draw a memory layout of pointers and variable(i-ii). What is the output (iii)? int x = 11; int y = 20; int* ptr; i) ii) iii) ptr=&y; *ptr=*ptr + x; cout << x<<" "<C Program Pass-by-reference in Functions Using Pointers Write a function swap that swaps the values of three integers x,y, and z. x is swapped to y, then y to z, and lastly z to x. In the main function, write a program that ask for theee integer inputs and pass in the reference of those variables by calling swap function. more details below the photo.Review these A reference is another name given to a variable in memory of the same data type A pointer is a variable that contains the address of another variable of the same type. Q1) The fun takes a reference and return a value int fun (int &x) { x=9; return x; } int main() { int x=4; int &z=x; int k=fun (z); cout<Match the following memory/pointer concepts and code structures: Leading asterisk, like *p pointer reference Trailing asterisk, like int* pointer variable data type Leading ampersand, like &a the thing pointed to by a poin v Trailing ampersand, like int& the memory location of a varia v Trailing star-ampersand, like int*& non-pointer referenceDescribe the design problems for the type of pointers. Pointers in the majority of programming languages can only point to a single type variable.Write a C/C++ function that receives, as arguments, a pointer to a double array, as well as the number of elements in the array (int). The function must use pointer operations (no block notation such as arr[i]) and must display each element in the array.c++ make a simple prrogram that takes random 2d array entered by user and organizes it use pointers for example if the user enter ((8,4),(3,4),(7,2),(8,6),(3,1)) no limit to number of sets use pointers there should be a function called transformer that will transform them into the right order and a funtion called display that will display what was inputed then it would organize it into ((4,8),(3,4),(2,7),(6,8),(1,3)) IT should only modify it and not make a copy of it.Lab 09 Understanding C++ pointers Assume p1, p2, and p3 are pointers to integer numbers. As an example, consider int n1 = 33; int n2 = 11; int n3 = 22; You are asked to implement the function void arrangelnOrder(int* p1, int* p2, int* p3) The function's goal is to order the data referenced by the pointers in such a way that after the function is called, p1 points to the smallest and p3 points to the largest of the three values. Test your function using the following main() method. Make sure your app works for all possible combinations of integer values referenced by the pointers. int main() { int n1 = 33; int n2 = 11; int n3 = 22; cout << "Before the call. n1=" << n1<< ", n2="<< n2 << ", n3=" << n3 << endl; arrangelnOrder(&n1, &n2, &n3); cout << "After the call. n1=" << n1 << ", n2=" << n2 << ", n3=" << n3 << endl; } It should produce the following output. Before the call. n1=33, n2=11, n3=22 After the call. n1=11, n2=22, n3=33 NOTE. Do not copy the data value into an array/vector and…The following C code containts a significant error in its use of pointers. Describe this error and indicate how it can be fixed.SEE MORE QUESTIONSRecommended textbooks for youC++ for Engineers and ScientistsComputer ScienceISBN:9781133187844Author:Bronson, Gary J.Publisher:Course Technology PtrSystems ArchitectureComputer ScienceISBN:9781305080195Author:Stephen D.
