Using C++ Programming language: Assume you define a vector in the following way: vector<int> vec; Assign the value 10 to the first element of this vector. What is the statement you would use?

Write three functions for: mean, remove, display //include any standard libraries needed // - passes in an array along with the size of the array // - returns the mean of all values stored in the array double mean( const double array [ ], int arraySize); // - Passes in an array, the size of the array by reference, and the index of a value to be removed from the array. // - Removes the value at this index by shifting all of the values after this value up, keeping the same relative order of all values not removed. // - Refuces arraySize by 1. void remove (double array[], not &arraySize, int index); // - Passes in an array and the size of the array. // - outputs each value in the array separated by a comma and space, with mo comma, space or beeline at the end. void display (const double array[], int arraySize); const int ARR_CAP = 100; int main (int argc, char *argv[]){// verify file name provided on command line // open file and verify it opened // declare an array of doubles of...

Instructions: You are strictly not allowed to use anything other than pointers and dynamic memory. One function should perform one functionality only. Task 1 Write a program in C++ that reads data from a file. Create dynamic memory according to the data. Now your task is to perform the following task. Row wise Sum Column wise Sum Diagonal wise Sum Example data.txt 4 5 1.6 10.2 33.7 99 20.5 3 44 50 96.1 2 8 9 4 74 50 99 19.1 Output: Sum row wise: 165, 191, 17, 242.1 Sum col wise: 127.6, 120.1, 228.8, 118.1, 20.5 Sum diagonal wise: Not Possible Note: You are restricted to use pointers and your function should be generic. Avoid memory wastage, memory leakage, dangling pointer. Use regrow or shrink concepts if required.

m05B C++ Please extend my code to do the following: Write a brand new driver program that does the following: Creates a circle object circleOne at (0,0):5. Creates a pointer c1Ptr to circleOne Creates a circle object circleTwo at (-2,-2): 10 Creates a pointer c2Ptr to circleTwo Use greaterThan to check if circleTwo is bigger than circleOne and display results Declare an array of pointers to circles- circlePointerArray Call a function with signature inputData(circlePointerArray, string filename) that reads data from a file called dataLab4.txt into the array The following h-k are done in this function Use istringstream to create an input string stream called instream. Initialize it with each string that is read from the data file using the getline method. Read the coordinates for the center and the radius from instream to create the circles Include a try catch statement to take care of the exception that would occur if there was a file open error. Display the message "File Open Error"...

Please use this template: #include <stdio.h>#define MAX 100struct cg { // structure to hold x and y coordinates and massfloat x, y, mass;}masses[MAX];int readin(void){/* Write this function to read in the datainto the array massesnote that this function should return the number ofmasses read in from the file */}void computecg(int n_masses){/* Write this function to compute the C of Gand print the result */}int main(void){int number;if((number = readin()) > 0)computecg(number);return 0;}Testing your workTypical Input from keyboard:40 0 10 1 11 0 11 1 1Typical Output to screen:CoG coordinates are: x = 0.50 y = 0.50

A1: File Handling with struct C++ This program is to read a given file and display the information about employees according to the type of employee. Specifically, the requirements are as follows. Read the given file of the information of employees. Store the information in an array or arrays. Display all the salaried employees first and then the hourly employees Prompt the user to enter an SSN and find the corresponding employee and display the information of that employee.

1) Define a global variable Emps that is an array of pointers to employee structs. 2) Change your createEmployee function to add the new employee to the Emps array. It should place it in the first slot that contains a NULL. 3) Write a listEmployees function that will call your display function on each employee in the array. 4) Change main to have a loop that looks for user commands. • If the user types HIRE, you should call createEmployee. If the user types LIST, you should call listEmployees. • If the user types QUIT, you should exit the loop, which will then cause the program to exit. 5) Write a findEmployee function that takes a string parameter and returns the employee pointer with that name or NULL if no such person exists. Change main to add a FIND name command that will find and display a single employee.

Game of Hunt in C++ language Create the 'Game of Hunt'. The computer ‘hides’ the treasure at a random location in a 10x10 matrix. The user guesses the location by entering a row and column values. The game ends when the user locates the treasure or the treasure value is less than or equal to zero. Guesses in the wrong location will provide clues such as a compass direction or number of squares horizontally or vertically to the treasure. Using the random number generator, display one of the following in the board where the player made their guess: U# Treasure is up ‘#’ on the vertical axis (where # represents an integer number). D# Treasure is down ‘#’ on the vertical axis (where # represents an integer number) || Treasure is in this row, not up or down from the guess location. -> Treasure is to the right. <- Treasure is to the left. -- Treasure is in the same column, not left or right. +$ Adds 50ドル to treasure and no 50ドル turn loss. -$ Subtracts...
