Please code in c
1. Write a program which does the following: Declare and initialize three pointers. One points to an integer, one points to a float and one points to a character variable Ask the user to enter appropriate values for these variables. Output the values to the screen by accessing the variables directly and then by using pointer references. Print the address of each variable. Modify the variables by performing any arithmetic operation only using pointer refer- ences...
Lab 8 CS102 Lab 8 Hands on programming with Pointers The goal of this lab exercise is to apply the knowledge of pointers and File input output operations. Program 1 Short description: Declare, initialize and use pointers for different data types. Detailed Description: Declare 4 variables of type's int, float, double and char respectively and initialize them to some logically correct values. Declare pointers to all these variables. Initialize the pointers to point to these variables respectively Print the values...
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...

I need help with my coding for C++! The goal of this is to calculate the total cost of a product by combining the products price and the amount of tax, then display it to the user. The numbers we have to test out is 100 for the price and 8.25 for the percentage. When I test is out, the formula works but it isn't rounding the 108.25 to 108.3, which is the total price we are supposed to display...
I need help doing the requirements listed below. Please don't delete comments. #include #include #include #include "Imager.h" /// 5 points : The program compiles without errors and warnings /// 5 points : The program operates correctly using namespace std; int main() { /// 2 points: Create an instance of two integers called "inX" and "inY". /// 2 points: Create an instance of the Imager class called "myImager". /// 2 points: Create a file input stream called "fileInStream". /// 2 points:...
C++. Please note the BOLDED ITEMS. You will create a simple linked structure. You will use a simple node that has a pointer to a Node. The data for the Node will be a single data member of type char. You will build a structure where the last node you add will point to the first node created, i.e. it will be a circular linked structure. You will create a program that stores characters provided by the user, stored in...
Need help about C PROGRAMMING,, pls use only C LANGUAGE.., yea so
im doing this exercise as a practice for c programming, could
someone do this as well so i could compare if my code makes makes
sense and to see and help correct the errors im getting right
now..
Any helpful help would be appreciated..

Can anyone help me with my C hw?
Exercise 3 You will write a new program that combines dynamically allocating an array and saving that array to a file. These are the tasks your program must perform Open an output file named "data.txt" and prepare it for writing in text mode o If the file handle is NULL, quit the program o By default, it is created and stored in the same directory as your source code file Prompt the...
