[solved] – Question 71515
Design, implement and test a C++ program which will process a list of names, sort them using selection sort, and save the output to a file.
Requirements
Process a data file of “student” names. See provided sample file
Include a function to sort the names in ascending or descending order using selection sort
Include another function to display the names BEFORE as well as AFTER it is sorted
Include yet another function to save the sorted names to a data file named Output_SortedNames.txt.”
Including main (), 4 or more functions must be implemented. Proper prototypes should be utilized and function bodies must be coded after the main function
Assume that the input data file will contain between 20 and 50 names where each name is written on a separate line and is constructed correctly
Input Validations –
“Reasonable” input and output validations are expected for this project
For example, if there is an error while attempting to open the input file, display an appropriate error message

[solved] – Question 71516
Write a program that lets the user enter a charge account number. The program should determine if the number is valid by checking for it in the following list:
5658845 8080152 1005231 4520125 4562555 6545231
7895122 5552012 3852085 8777541 5050552 7576651
8451277 7825877 7881200 1302850 1250255 4581002
Initialize a one-dimensional array with these values. Then use a simple linear search to locate the number entered by the user. If the user enters a number that is in the array, the program should display a message saying the number is valid. If the user enters a number not in the array, the program should display a message indicating it is invalid.

[solved] – Question 71576
Write a code that will calculate randomly a number between 1 and 10 (without displaying it) and will ask the user to guess it. If the user answers correctly, the program prints “Good” and add 1 to his score, if not, the program prints “sorry”, gives the correct answer, then selects another number. After 10 consecutive games, the programs stops and prints the final score. Hint: use a random buitin function (rand) and write the #include <stdlib.h> at the beginning.
your guess? 7 Sorry, answer was 5 your guess? 6 Sorry, answer was 0 your guess? 3 Sorry, answer was 1 your guess? 9 Sorry, answer was 0 …..
your guess? 1
Sorry, answer was 5
your final score is 0

[solved] – Question 71577
Write a program which repeatedly reads numbers until the user enters 0. Once 0 is entered, print out the total, count, and average of the numbers. Use an array to store all the numbers. Example of execution:
Enter a number: 4
Enter a number: 5
Enter a number: 9
Enter a number: 0
Total = 18, count = 3, average= 6

[solved] – Question 71582
This program will always print a menu of 5 options. If user chooses for example 1 (addition), the program will ask him to enter 2 numbers that the program will add to each other. Then, the menu options are printed again and so on… If user chooses 5 (quit), the program will stop. Below an example of execution (user’s input is in red). Write the program where the menu is a function, as well as the 4 calculus operations (addition, subtraction…)
Welcome to calculator your options are: 1) Addition
2)Subtraction
3)Multiplication
4)Division
5)Quit calculator
Choose your option: 1
Add this: 3 to this: 4 3 + 4 = 7 Welcome to calculator your options are: 1) Addition
