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.

C++ Programming: From Problem Analysis to Program Design
- 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_forward4. A user enters an email address in a string variable in C++. Write a program that displays whether the email address contains any digit or not.arrow_forward

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. Begin the program by declaring variables…arrow_forward
