Computer Operations, Solving Problems, and Algorithms
In today’s technological market, there consists of a multitude of application software to provide the top-of-the line operating system software. To achieve the standard operating software there are various elements to consider. These elements consist of six major operations, problem solving techniques, and algorithmic coding.
The six major computer operations:
  1. A computer can receive information.
The verbs Read and Get are used in the pseudocode, when a computer is required to receive input from a particular source, whether it is a terminal, a disk or any other device. The verb Read is used when the algorithm is used to receive input from a record on a file. The verb Get is used when the algorithm is to receive input from the keyboard.
  2. A computer can put out information
When a computer is required to supply information or output to a device, the verbs Print, Write, Put, Output or Display are used in the pseudocode. Print is usually used when the output is to be sent to the printer, while Write is used when the output is to be written to a file. If the output is to be written to the screen, the words Put, Output or Display are used in the pseudocode. An output Prompt instruction is usually required before an input Get instruction. The Prompt verb is used when information is sent to the screen, which requires the user to respond, usually by providing input.
  3. A computer can perform arithmetic
A computer can perform some sort of mathematical calculation, or apply a formula. Programmer can use actual mathematical symbols or the words for those symbols. For example:
add number to total
total = total + number
The symbols that can be used in pseudocode are listed below:
+ for add
for subtract
for multiply
/ for divide
( ) for parentheses
The verbs Compute and Calculate are also used in pseudocode.... [continues]
