Pseudo Code

Pseudo code

Pseudo code is a detailed yet readable description of what a computer program must do, expressed in a formally-styled natural language rather than in a programming language. Pseudo code is sometimes used as a detailed step in the process of developing a program. It allows designers to express the design in great detail and provides programmers a detailed template for the next step of writing code in a specific programming language. I have chosen to create a pseudo code because I found that this tells the user a step by step process on how to convert decimal to binary or binary to decimal.

A flow chart is a graphical or symbolic representation of a process. Each step in the process is represented by a different symbol and contains a short description of the process step. The flow chart symbols are linked together with arrows showing the process flow direction.
The oval at the top of the program is utilized to indicate the beginning of a program. A diamond flow chart shape indicates a branch in the process flow. Here, the program offers the user a decision of whether to convert decimal to binary or binary to decimal.
If the user chooses decimal to binary, then the program will execute the following:
The user will input a decimal number, which is a parallelogram that indicates data input for a process. The program would then check to see if the decimal number that has been inputted is between 0 and 255. If the decimal number isn’t between 0 and 255, then the program will go back to the previous process (input a decimal number.) The program will then divide the decimal number by 2. The next step would then store the remainders of all the division as binary and the answer is stored as decimal. The program then checks to see if the decimal number is equal to 0. If this isn’t the case, then the program will return to the stage where the decimal number is divided by 2. If the statement is correct, then the program can output all of the remainders from all of the divisions as binary. The following stage outputs binary. The final stage ”end” indicates the end of the program.
If the user chooses binary to decimal, then the program will execute the following:
The user will input a binary number, which is a parallelogram that indicates data input for a process. The program will then check to see if the binary number entered is between 0-8 bits long. If the binary number isn’t between 0-8 bits, then the program will return back to the stage – input binary number. The program then checks to see if the binary number consists of 1s and 0s. If the binary number doesn’t consist of 1s and 0s then then the program will return back to the stage – input binary number.
