Welcome back, all!
I will be posting my college days adventure in this blog. So far I have taken or are taking the following classes since my return to school.
Beginning Java
Project Management
Beginning Visual Basic
Beginning C++
Introduction to Computer Security
U.S. History II
And here's a program I wrote in school that earn a grade of A and was shown to everyone in class as to the proper way to write a program.
It is a very basic C++ program. It is self-explanatory. You can run it if you have a C++ compiler in your computer.

This C++ source code contains 3 different programs.
Variables used inside main function.
GREETING: greeting begins each program.
inputEnter: user input variable before exiting program.

// Include header files in preprocessor directives.
#include <iostream> //Needed for input and output operations.
#include <string> //Needed to declare string objects.
#include <iomanip> //Needed to set precision for first program.
// State namespace to use in this statement.
using namespace std; //Needed to simplify syntax of iostream objects.
// Begin main function.
int main() //Main function header starts the program.

// First Program: Adding Taxes To A Purchase
//
// Program asks user to enter amount of purchase for an item.
// Program then computes the federal, state and county taxes.
// This program uses a state tax of 8%, a federal tax of 12%, and a
// county tax of 3%.
// Program then displays the amount of purchase, all three taxes, and
// the purchase amount that includes all three taxes.
//
// Input variable of this program:
// purchaseAmount: purchase amount of item.
//
// Named constant variables of this program:
// FEDERAL_TAX_RATE: federal tax rate in decimal.
// STATE_TAX_RATE: state tax rate in decimal.
// COUNTY_TAX_RATE: county tax rate in decimal.
//
// Output variables of this program:
// federalTax: federal tax of item.
// stateTax: state tax of item.
// countyTax: county tax of item.
// purchaseAmountWithTaxes: final price of item including all 3 taxes.

//Ask user to enter amount of purchase.
cout << "Please enter the amount of purchase for the item: ";
cin >> purchaseAmount; //Assign purchase amount to a variable.
//Calculate all three taxes.
federalTax = purchaseAmount * FEDERAL_TAX_RATE;
stateTax = purchaseAmount * STATE_TAX_RATE;
countyTax = purchaseAmount * COUNTY_TAX_RATE;
purchaseAmountWithTaxes = purchaseAmount + federalTax + stateTax
+ countyTax; //Adds up all taxes and the purchase amount.
//Display the purchase amount, the tax rates, the tax amounts, and
//the final price.
cout << setprecision(2) << fixed; //sets numbers to 2 decimal places.

// Second Program: Simple Word Game
//
// Program asks user to enter name, age, city, and an abbreviated college
// name. This program assumes that none of the input values have spaces
// in them.
// Program then displays the following story replacing the user’s input
// in appropriate locations:
// A person named "name" who lived in "city" was "age" years old and goes
// to a college named "abbreviated college name".
//
// Input variables of this program:
// name: name entered by user.
// age: age entered by user.
// city: city entered by user.
// collegeName: abbreviated college name entered by user.
//
// Output variables of this program are all the input variables.
//***************************************************************************
//Declare local variables.
string name, city, collegeName;
int age;
//Ask user for name, age, city, and abbreviated college name.
cout << "Please enter the following information:" << endl;

cin >> name;
cout << "Your Age: ";
cin >> age;
cout << "Your City: ";
cin >> city;
cout << "Your abbreviated College Name (Example, CSN): ";

//Display the following story output.

//Greet user to third program.
cout << "\n\n" << GREETING << "3\n\n\n";
//***************************************************************************
// Third Program: Elapse Time In Seconds
//
// Program asks user to input the elapsed time for an event in hours,
// minutes, and seconds. The program then outputs the elapsed time in
// seconds.
//
// Input variables of this program:
// hours: hours of elapsed time.
// minutes: minutes of elapsed time.
// seconds: seconds of elapsed time.
//
// Output variable of this program:
// elapsedTimeInSeconds: total elapsed time in seconds.

<< "minutes, and seconds.\n";
cout << "Hours: ";
cin >> hours; //Object cin automatically returns new line.
cout << "Minutes: ";
cin >> minutes; //Object cin automatically returns new line.
cout << "Seconds: ";
cin >> seconds; //Object cin automatically returns new line.
//Compute elapsed time by converting hours into seconds and
//minutes into seconds and adding all the seconds together.

<< "interactive programs." << endl << endl; //double space.
