C+++ CODE HELP WITH POINTER BASICS CODE TO DO THE FOLLOWING: In function DisplayRank(), if rankPointer is null, print "rankPointer is null.". Otherwise, print the value in the variable pointed to by rankPointer. End with a newline. Ex: If the input is Y D, then the output is: D #include using namespace std; void DisplayRank(char* rankPointer) { /* Your code goes here */ } int main() { char rank; char* rankPointer; char action; rank = '0'; cin >> action; cin >> rank; if (action == 'Y') { rankPointer = &rank; } else { rankPointer = nullptr; } DisplayRank(rankPointer); return 0; }

In C programming: Write a main() function using the following requirements:• Define a SIZE constant (the value is irrelevant, but for testing, you may want to keep it small enough – no bigger than 5)• Create an array of course pointers using SIZE• Dynamically allocate each element of the array• Call inputAllCourses()• Call printAllCourses().

In the following program with struct student, which has name and age. There is a pointer to struct student *ptr, but does not assign a value to it. Then, there is a print statement for ptr->age. 1. Why does an error occur when the program is run? #include <stdio.h> //make struct student struct student { charname[25]; int age; }; int main() { //declare pointer to struct student struct student *ptr; //print ptr -> age printf("%d", ptr->age); return0; }

IN C PROGRAMMING LANGUAGE: Please write a pointer version of squeeze() named psqueeze(char *s, char c) which removes c from the string s.

C++, Please add a function where it can display the median, the maximum number, the minimum number, in an array entered by the user. Code: #include<iostream> using namespace std; class Search_Dynamic_Array { public: Search_Dynamic_Array(); int getArrSize(); void getArray(); void setArrsize(int); void setArray(int*); int getSum(int*); private: int arr_size; int arr[]; }; Search_Dynamic_Array::Search_Dynamic_Array() { //ctor } int Search_Dynamic_Array::getArrSize() { return arr_size; } void Search_Dynamic_Array::getArray() { cout << "The elements of the array are: "; for(int i=0; i<arr_size; i++){ cout << arr[i] << " "; } } void Search_Dynamic_Array::setArrsize(int s) { arr_size=s; } void Search_Dynamic_Array::setArray(int a[]) { for(int i=0; i<arr_size; i++){ arr[i]=a[i]; } } int Search_Dynamic_Array::getSum(int a[]) { int sum; for(int i=0; i<arr_size; i++){ sum +=arr[i]; } return sum; } int main() { int s=1, a[s]; cout << "Enter the size of the...

Write a C++ function definition named containsNumber. The function should take three parameters: a one-dimensional integer array, the number of entries in the array, and an integer value. The function should search the array for the integer value and return a boolean value of true if the value is found and false otherwise. Below is a example call to the function: valueFound = containsNumber(table, nbrOfEntries, value); You may assume that all parameters passed to the function are valid, that the nbrOfEntries amount is always greater than or equal to one, and that a specific integer value occurs at most once in the table. Remember to only write the function definition for the containsNumber function. Do not write a complete C++ program.

1- Write a user-defined function that accepts an array of integers. The function should generate the percentage each value in the array is of the total of all array values. Store the % value in another array. That array should also be declared as a formal parameter of the function. 2- In the main function, create a prompt that asks the user for inputs to the array. Ask the user to enter up to 20 values, and type -1 when done. (-1 is the sentinel value). It marks the end of the array. A user can put in any number of variables up to 20 (20 is the size of the array, it could be partially filled). 3- Display a table like the following example, showing each data value and what percentage each value is of the total of all array values. Do this by invoking the function in part 1.

C++ Double Pointer: Can you draw picture of what this means : Food **table? struct Food { int expiration_date; string brand; } Food **table; What is this double pointer saying? I know its a 2D matrix but I don't understand what I'm dealing with here. Does the statement mean that we have an array of pointers of type Food and what is the other * mean? I'm confused.

use c++ Programming language Write a program that creates a two dimensional array initialized with test data. Use any data type you wish . The program should have following functions: .getAverage: This function should accept a two dimensional array as its argument and return the average of each row (each student have their average) and each column (class test average) all the values in the array. .getRowTotal: This function should accept a two dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a row in the array. The function should return the total of the values in the specified row. .getColumnTotal: This function should accept a two dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a column in the array. The function should return the total of the values in the specified column. .getHighestInRow: This function should accept a two...

In C, in order to do operations to the data being referenced by a pointer you would need to use the (*) operator, which is called ______________ operator.

Language: C Write the function convolve that will calculate the confolution of two functions f, g on [0, t] interval. The convolution is defined as (f ∗ g)(t) = Z t 0 f(τ )g(t − τ ) dτ for f, g : [0, ∞) → R. The argument function f and g should be passed by pointers. The integral should be approximated by the Riemman sum, i.e., Z b a f(x) dx = Xn i=1 f(xi) ∆x, where ∆x = b−a n and xi = a + i ∆x. Define the functions func1, func2 and func3, that return sin(x), cos(x) and x 3 respectively. Use these functions to calculate the convolution of ˆ f = sin(x), g = sin(x) ˆ f = sin(x), g = cos(x) ˆ f = sin(x), g = x 3 for t = 2π and n = 1000.

help me solve this in c++ please Write a program that asks the user to enter a list of numbers from 1 to 9 in random order, creates and displays the corresponding 3 by 3 square, and determines whether the resulting square is a Lo Shu Magic Square. Notes Create the square by filling the numbers entered from left to right, top to bottom. Input validation - Do not accept numbers outside the range. Do not accept repeats. Must use two-dimensional arrays in the implementation. Functional decomposition — Program should rely on functions that are consistent with the algorithm.
