Rewrite the program you submitted for A8 to use pointers, pointer notation and arithmetic, etc. as...
Here's an assignment that'll give you some practice with pointers. All you have to do is write a program that allows the user to populate an array of doubles (5 values) by calling the function InitArray. After the user has entered all the values, then call the function DispRevArray to display the array in reverse. Main will create and allocate space for an array of type double for 5 elements. Then you will create and allocate a pointer that will...
Write in C code: Define an array f=[23,-12,34,-56,-10,12,19], using call-by-reference (use pointers), to pass the array to a function, named Summation. In main: Define array, pass array, print out the array and the result returned from Summation on screen. In function Summation: 1)take array and size from main 2) sum each element according to the following rules 3) if the value of f(i) is positive, add 2*f(i) to the sum 4)if the value of f(i) is negative, add -3*f(i) to...
Hello I need help with this program. Should programmed in C! Program 2: Sorting with Pointers Sometimes we're given an array of data that we need to be able to view in sorted order while leaving the original order unchanged. In such cases we could sort the data set, but then we would lose the information contained in the original order. We need a better solution. One solution might be to create a duplicate of the data set, perhaps make...
In Exercise 1, displayAnimal uses an Animal reference variable as its parameter. Change your code to make the displayAnimal function anim parameter as an object variable, not a reference variable. Run the code and examine the output. What has changed? Polymorphic behavior is not possible when an object is passed by value. Even though printClassName is declared virtual, static binding still takes place because anim is not a reference variable or a pointer. Alternatively we could have used an Animal...
please use c ++ language and write the comment too. thanks Pointer Arithmetic Write a function that passes an array address to a function as a pointer. Using pointer arithmetic, the function determines the average, high, and low value of the array. Your function should have this header: void pointerArithmetic(int *array, int size, double &average, int &high, int &low) Parameter size is the number of elements in array. You may not use the subscript notation [] inside your function –...
C programming. 1.Create a program that does the following - Creates three pointers, a character pointer professor, and two integer pointers student_ids, grades - Using dynamic memory, use calloc to allocate 256 characters for the professor pointer - Prompts the professor for their name, and the number of students to mark. - Stores the professor’s name using the professor pointer and in an integer the number of students to mark. - Using dynamic memory, use malloc to allocate memory for...
C programming 3. (40 pts) Define an array fof size 10, using call-by-reference (that is, use of pointers), to pass the array to a function, named summation In main: define array, pass array, print out the array and the results on screen In function summation: take array from main and sum the array using the formula below: 10 fO 2 246 NOTE: you must use call-by-reference (the pointer) to call functions, as required; otherwise, no credits will be given.
C++ Program Int Main First Please Write one program that does the following: 1. 1. Ask the user for ten (10) grades, and store the data in an array. Compute the average of all the grades. Print the original ten grades and the average. a. Declare an integer array with the name of “grades” of size 10 in the main function. b. Create a function called “getGrades” that prompts the User for the grades and puts them in an integer array. i. The function will receive...
c++ if you answer the question please write it line by line and not in paragrapth form. Write a C++ program that uses a structure named Movie to store the following. a. Title b. Director c. Year Released d. Running time (in minutes) e. Cost of production f. Revenue (first year). Create an array of type Movie of size 3. In your main program should then have in a loop (3 times) called a function called getData() and the purpose...
