Develop a program that will determine the gross pay for each of several employees. The company pays “straight-time” for the first 40 hours worked by each employee and pays “time-and-a-half” for all hours worked in excess of 40 hours. You are given a list of the employees of the company, the number of hours each employee worked last week and the hourly rate of each employee. Your program should input this information for each employee, and should determine and display the employee’s gross pay.

The simple interest on a loan is calculated by the formula. interest = principal * rate * days / 365; The preceding formula assumes that rate is the annual interest rate, and therefore includes the division by 365 (days). Develop a program that will input principal, rate and days for several loans, and will calculate and display the simple interest for each loan, using the preceding formula.

One large chemical company pays its salespeople on a commission basis. The salespeople receive $200 per week plus 9% of their gross sales for that week. For example, a salesperson who sells $5000 worth of chemicals in a week receives $200 plus 9% of $5000, or a total of $650. Develop a program that will input each salesperson’s gross sales for last week and will calculate and display that salesperson’s earnings. Process one salesperson’s figures at a time.

Develop a program that will determine if a department store customer has exceeded the credit limit on a charge account. For each customer, the following facts are available: 1. Account number 2. Balance at the beginning of the month 3. Total of all items charged by this customer this month 4. Total of all credits applied to this customer’s account this month 5.

Drivers are concerned with the mileage obtained by their automobiles. One driver has kept track of several tankfuls of gasoline by recording miles driven and gallons used for each tankful. Develop a program that will input the miles driven and gallons used for each tankful. The program should calculate and display the miles per gallon obtained for each tankful. After processing all input information, the program should calculate and print the combined miles per gallon obtained for all tankfuls.

Java Language

The "Java" word means depending from its context either Java Platform or Java Language. Java language is an object oriented language form Oracle with a syntax similar to that of C. The Java language attempts to protect the programmer form common C and C++ gotchas. Its scoping is not as complex as C++, but provides separate name spaces via packages and a range of other protections surrounding class. Java has been positioned as an excellent language for developing network-based applications.It is multi-threaded, and many of its libraries are thread-safe.

C/C++ Tutorial

 C++ (pronounced "see plus plus") is a statistically typed,free-form,multi-paradigm, compiled,general-purpose programming language.It is regarded as an intermediate-level language, as it comprises a combination of both high-level and low-level language features. Originally named C with Classes, the language was renamed C++ in 1983, as pun involving the increment operator.It is one of the most popular programming languages and implemented on wide variety of hardware and operating system platforms. An an efficient compiler to native code, its application domains include system software, application software, device drivers, embedded software, high-performance server and client applications, and entertainment software such as video games.

The most common greetings used in Programming and my first post in my Blog. Blog created minutes ago before this post. Around 11: 00 am January 17,2013. The purpose of this blog is to help and give information to all my co - FUTURE PROGRAMMER even though I'm not yet expert to this field so, I just want only to share my little knowledge about programming and other stuffs about Computers.

God Bless! and continue Compiling! :)
