Answer: static_cast<float>operator used for compile time cast. It is used for conversion…

(YOU ARE NOT ALLOWED TO USE ARRAYLIST IN THIS PROJECT)Write a Java program to simulate a blackjack game of cards. The computer will play the role of the dealer. The program will randomly generate the cards dealt to the player and dealer during the game. Cards in this game will be represented by numbers 1 to 13 with Ace being represented by a 1. Remember, that face cards (i.e. Jack, Queen, and King) are worth 10 points to a hand while an Ace can be worth 1 or 11 points depending on the user’s choice. The numbered cards are worth their number value to the hand.
"Type" doesn't specify a variable. Variables have data types. How can this idea explain any variable?
C++ continued you already gave me the help from the first part. now they have added another set of instructions. original code used. Explanation Here I have created the main method. Inside the main method, I have taken input from the user for height and width and stored them into different variables. Next, I have created a loop that runs till it reaches the height of the rectangle. Inside the loop, I have created another loop that runs till the width of the rectangle. In the inner loop, I have printed the asterisk symbol. After the inner loop, I have used endl to give break and move the pointer to the new line. arrow_forward Answer C++ code: #include<iostream>using namespace std; int main(){ int height, width; // user input cin >> height >> width; // outer loop for(int i = 0; i < height; i++) { // inner loop for(int j = 0; j < width; j++) { //printing the * symbol cout << "*"; }…
Write VBA CODE FOR THE FOLLOWING PROBLEM Problem: The Worksheet named Grades contains a place for students to record the grades they have received in their classes. Students put the number of each letter grade received in the B column. (For example, the worksheet currently shows that the student has taken 9 classes and made five As, one B, one C, one D, and one F as grades. You need to write a program that reads the grades from the worksheet and uses a function to calculate the student’s GPA. For this problem you can assume that all classes are worth the same number of credit hours. The function should send back the GPA to the calling procedure. The procedure will then put up a message box that gives the student their GPA and a message about their GPA, all in one message box. The message should be “You qualify for an internship” if the student has a GPA of at least 3.0. It should be “You’re in the danger zone” if the GPA is between 2.0 and 3.0. And it should be “You are on…

Using C++ For each game played you will write the final results for the player and the computer. The data written should look like this: 19 21 18 23 21 16 You will have the player data first, a tab '\t', and then the computer result followed by a newline '\n' So, in the example above, in the first game, the player got 19 and the computer got 21. In the second game, the player got 18 and the computer got 23. After the player stops the program, you will close the writing file stream and open the input file stream of the newly created file. Read each line of numbers and calculate: The average result of the player for all the games played. The average result of the computer for all the games played. The total wins for the player and the computer. Then, declare who is the best 21 player! The output from above will look like this assuming the computer is named, "Ruby." Your game average was 19.3 Ruby's game average was 20.0 You won 2…
