Implementation of a
Program Plan:
Write a C++ program with a main function and the required set of statements to accomplish the following:
Write a C++ statement that includes the header file iostream
Write a C++ statement that allows you to use cin, cout, and endl without the prefix std::.
Write C++ statement(s) that declare the following variables: num1, num2, num3, and average of type int.
Write C++ statements that store 125 into num1, 28 into num2, and -25 into num3
Write a C++ statement that stores the average of num1, num2, and num3 into average
Write C++ statement(s) that output the values of num1, num2, num3, and average

C++ Programming: From Problem Analysis to Program Design
- C++ beginner class practice problem Please put //comments in so I understand the program Consider the following incomplete C++ program: #include <iostream> int main(){ ...} Write statements that include the header files fstream, string, and iomanip in this program. Proceed through all the steps in this activity by clicking on the Next Step button below after completing each step. Write statements that declare inFile to be an ifstream variable and outFile to be an ofstream variable. The program will read data from the file inData.txt and write output to the file outData.txt. Write statements to: Open both of these files Associate inFile with inData.txt Associate outFile with outData.txt Suppose that the file inData.txt, data set 1, contains the following data: Giselle Robinson Accounting 5600 5 30 450 9 75 1.5 Write statements that close the input and output files. The file inData.txt is provided for you with the following data: Giselle Robinson Accounting 5600 5 30 450…arrow_forwardQ/In C++, the following expression is an expression "a='x' || b='y' " logical expression arithmetic expression O figurative expression The expression is incorrectarrow_forwardProgramming Language: C++ 1.

- in c++ add the request for the month number and read it in, add the request for the year and read it in, Ask what format the user would like to see the date in and write the if statement that will use the value in (format variable) to print out the date in the correct format. */ #include <iostream> using namespace std; int main() { short day, month, year, format; // Request day of the month (as a number) and put in day variable cout << "Enter a day of the month (1, 12, 30, etc): "; cin >> day; cout << "Formats are (1) YYYY/MM/DD, (2) DD/MM/YYYY, and (3) MM/DD/YYYY" << endl; cout << "Enter the number for the format you want (1, 2, or 3): "; cin >> format; }arrow_forwardin c++ Write a program to generate a random number between 1 - 100, and then display which quartile the number falls in. First quartile is 1 - 25 Second quartile is 26 - 50 Third quartile is 51 - 75 Fourth quartile is 76 - 100 To generate a random number, follow these steps: include necessary header files #include <cstdlib> //for random functions #include <ctime> //for time functions set constants for the minimum and maximum values of the desired range const int MIN_VALUE = 1; //minimum range value const int MAX_VALUE = 100; //maximum range value seed the random number generator (RNG) with a unique unsigned int value - system time! unsigned seed = time(0); //system time in seconds since 1/1/1970 srand(seed); //seed the RNG get a random number in the desired range int num = (rand() % (MAX_VALUE - MIN_VALUE + 1)) + MIN_VALUE; The program should: contain header comments as shown in class display a "hello" message (more descriptive than shown in sample)…arrow_forwardQ3:Write a C++ program which explain the use of C++ built-in operators, it should contain three expressions.

All information needed for this will be passed to the program on the command line. There will be no user input during the execution of the program You will need a few pieces of information. The price of the home and the amount of the down payment. You will also need to know the interest rate and the term of the mortgage. To figure your mortgage payment, start by converting your annual interest rate to a monthly interest rate by dividing by 12. Next, add 1 to the monthly rate. Third, multiply the number of years in the term of the mortgage by 12 to calculate the…arrow_forward
