Implementation of a
Program Plan:
Write a C++ program with a main function and the required set of statements to accomplish the following:
Write C++ statements that include the header files iostream and string
Write a C++ statement that allows you to use cin, cout, and endl without the prefix std::.
Write C++ statements that declare the following variables: name of type string and studyHours of type double
Write C++ statements that prompt and input a string into name and a double value into studyHours
Write a C++ statement that outputs the values of name and studyHours with the appropriate text. For example, if the value of name is "Donald" and the value of studyHours is 4.5, the output is,
Hello, Donald! on Saturday, you need to study 4.5 hours for the exam.

- 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_forwardC++ Programming. Theme: Standard string manipulation functions - string concatenation, comparison, character search, string search, replacement and deletion. Task : Write a program that replaces the second letter of every word in char string A with the third letter of every word in string B to get string S.arrow_forwardWrite a c++ program that uses a structure named Movie Data to store the following information about a movie. Title (string) Director (string) Year Released (int) Running Time (in minut) (int) The program should create two MovieDate variables; store values in their members, and display the information about movie.arrow_forward
- in 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_forwardExercise #3: Character Counts Write a c++ program that prompts the user to enter a string, calls the function lowerUpperDigits( ) which takes a string and counts the number of lower, upper, and digit characters in the string. The main program prints the number of found characters. int lowerUpperDigits(string, int&, int&); Sample input / output:arrow_forwardInstructions: In C++ Programming, write a program that calculates and prints the monthly paycheck for an employee. The net pay is calculated after taking the following deductions: Federal Income Tax: 15% State Tax: 3.5% Social Security Tax: 5.75% Medicare/Medicaid Tax: 2.75% Pension Plan: 5% Health Insurance: $75.00 Your program should prompt the user to input the gross amount and the employee name. The output will be stored in a file. Format your output to have two decimal places. A sample output follows: Bill Robinson Gross Amount: .......................... $3575.00 Federal Tax: ................................ $ 536.25 State Tax: .....................................$ 125.13 Social Security Tax: ................... $ 205.56 Medicare/Medicaid Tax: ......... $ 98.31 Pension Plan: .............................. $ 178.75 Health Insurance: .......................$ 75.00 Net Pay: ....................................... $2356.00arrow_forward
- in c language Write a program which performs the following actions: Write the header of the C program Write the beginning of the main function Initialize a string called first_string with the constant value "C programming is nice**" using a string pointers Initialize a string called second_string with the constant value "C language is difficult" using a string pointer Display first_string and second_string in two consecutive lines Display a message that shows if the two strings have the same length (hint: use sizeof). Assume now that both strings have the same size. Write only three statements to swap the two strings’ contents (swap means the content of the first string becomes the content of the second string and vice-versa) Display again the two strings to check whether they have been swapped Write the correct symbol to close the main functionarrow_forwardC++ Programming. Theme: Standard string manipulation functions - string concatenation, comparison, character search, string search, replacement and deletion. Task : Write a program that determines how many words of odd length are contained in string A of type String.arrow_forwardProgramming Language: C++ 1. A constant cannot be passed by reference. = true or false?arrow_forward
- C++ Programming I Program 4: C++ Craps Game Functions in files, random numbers , stringstream and precision Craps is a popular dice game played in casinos. The C++ variation is as follows: Make a bet. Roll two dice. Each die has six faces, representing values 1-6. Check the sum of the faces showing on the two dice.: If the sum is 2, 3 or 12 (craps), you lose. If the sum is 7 or 11 (natural), you win. If the sum is anything else, a point is established (the sum of the dice you rolled) and you continue to roll until you re-roll the point (you win) or you roll a 7 (you lose). This program will contain 6 functions to be called from main and from another function. The functions will be contained in two files: Functions.h, which contains the function prototypes, and Functions.cpp, which will contain the function implementations (or bodies). Do not forget to put include guards in the Functions.h file.
