- (Data processing) A bank’s customer records are to be stored in a file and read into a set of arrays so that a customer’s record can be accessed randomly by account number. Create the file by entering five customer records, with each record consisting of an integer account number (starting with account number 1000), a first name (maximum of 10 characters), a last name (maximum of 15 characters), and a double-precision number for the account balance. After the file is created, write a C++ program that requests a user-input account number and displays the corresponding name and account balance from the file.arrow_forward(Numerical) Write and test a function that returns the position of the largest and smallest values in an array of double-precision numbers.arrow_forward(List maintenance) The following letters are stored in an alphabet array: B, J, K, M, S, and Z. Write and test a function named adlet(), which accepts the alphabet array and a new letter as arguments, and then inserts the new letter in the correct alphabetical order in the array.arrow_forward
- (File creation) Write a C++ program that creates an array containing the integer numbers 60, 40, 80, 90, 120, 150, 130, 160, 170, and 200. Your program should then write the data in the array to a text file. (Alternatively, you can create the file with a text editor.)arrow_forwardTask 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 )arrow_forwardDeclare an integer pointer variable intPointer. Initialize it to point to an int variablenamed someInt.Assign the value 451 to someInt and output (cout) the variable someInt and output (cout)the value pointed to by intPointer.Write an assignment statement that indirectly stores 900 into the value pointed to by intPointer.Output (cout) the value pointed to by intPointer and output (cout) the variable someInt,arrow_forward
- Pointer Activity You do not need getopt for this program as there are no arguments. Call the executable pointers. Create variables for a character, a string, an integer, and a floating point number. Create pointers for each of those variables. Ideally, use the same name as the variable but add a p in front of the name. (For example: (total and ptotal) Ask the user to enter information for each of these variables one at a time. For each variable tell them what they should enter. (For example: “Enter a single character” or “Enter a floating point number”) Read in the information and put it in the variables. Make each pointer point to the respective variable. Print out values for the four variables without using the variables themselves. Only use the pointers. In addition print out the addresses of the memory locations that each pointer points to. You can use %p for that. Output should look like the bottom sample. Copy and paste the code and the output into a Word document and submit.…arrow_forwardGiven 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;}arrow_forward• R7.11A pointer variable can contain a pointer to a single variable, a pointer to an array, nullptr, or a random value. Write code that creates and sets four pointer variables a, b, c, and d to show each of these possibilities.arrow_forward
