Control Statements Building computer software begins with the programmer's choice of the three classes of control statements. Control statements process data, make decisions and repeat groups of instructions.

The sequence structure describes program statements executed one after the other. The programmer inserts branching statements into a program wherever the program needs to follow two or more courses of execution based upon the evaluation of a piece of data. The final group of control structures repeats a statement or group of statements a specified number of times or until a certain event occurs. Programming Instructions A key concept that a programmer must understand holds that the computer will only do what she tells it to do. All program instructions must accomplish a task in a step-by-step manner. For example, adding two numbers requires a number of steps: Get one number and then get the other, add the first number to the second and place this sum in a new memory location. The programmer cannot assume any portion of the arithmetic statement.

Repeating this addition problem requires that the programmer place it within a construct called a loop. The loop adds some new variables to the problem such as how many times to repeat the addition statements. Without the consideration of this requirement, the program can enter an infinite loop that crashes the computer. Many programming operations will follow one sequence of instructions if a condition is true (e.g., 'Is it windy outside?' ) and another sequence if it is false.

Branching control structures enable this capability within a program. Choosing a Programming Language Programmers must choose a language in which to work from among the hundreds of languages available. As of 2010, the most popular languages are C++, Visual Basic and Java. If the developer wants to target her software to the Internet environment, PHP and Ruby make excellent choices. Each of these languages is relatively complex, and the programmer should plan on spending some time learning the specific syntax of the chosen language before setting out to build a piece of software.

Choosing Development Tools The most important tool the programmer must select to build software is the compiler. Modern development environments combine all of the software tools needed to develop a program into a single suite. The programmer will use an editor to write the program statements and save them into a file. A compiler will read this file, checking the syntax as it does, and then convert the programming statements into instructions a specific computer processor and operating system can understand.

The result is an executable file that the programmer can use or sell. Programmers can use individual tools (editor, compiler, etc.), but the all-in-one suite makes the process much more convenient.

Preparing to Program Building computer software requires the proper tools, an understanding of a computer language and the ability to think logically. Software operates with hard logical constraints with no gray areas; the computer processor will not guess or make decisions on its own. The programmer should prepare to think through what he wants to accomplish with his design before sitting down at the keyboard to create a software masterpiece.

A good program will perform a task that makes life easier for the user. Look at the software that is currently available for the task you want to perform, and see if there are ways that the process could be easier or smoother. A successful program is one that users will find a lot of utility in.

• Examine your daily tasks on your computer. Is there some way that you could automate a portion of those tasks with a program?

Fx Forward Contract Template. • Write down every idea. Even if it seems silly or outlandish at the time, it could change into something useful or even brilliant. Learn a programming language.

All programs are created through coding. If you want to create your own programs, you will need to be familiar with at least one programming language. The languages you will need to learn will vary depending on the type of program you want to create. Some of the more useful and important ones include: • - C is a low-level language that interacts very closely with the computer's hardware.

It is one of the older programming languages that still sees widespread use. • - The biggest drawback of C is that it is not object-oriented. This is where C++ comes in. C++ is currently the most popular programming language in the world.
