2 2 flowcharts flowcharting is a tool developed in the computer industry for showing the steps involved in a process.

Flowchart and pseudocode examples pdf. Pseudocode is an artificial and informal language that helps programmers develop algorithms. An algorithm is a step by step analysis of the process while a flowchart explains the steps of a program in a graphical way. Algorithm and flowcharts helps to clarify all the steps for solving the problem. Strictly speaking the above flowchart corresponds more to the pseudocode on the right hand side.

Example 3 write an algorithm and draw a flowchart that will read the two sides of a rectangle and calculate its area. Pseudo code example 4 fill the array with random variables pseudo code example 4 is very concise description of the algorithm and most programmers know how to implement it. Since there is a use of the loopcounter to succeed to the next element in the array the for loop is vital. However as you can see gotos make code less modular and more unreadable.

Artificial language based on vocabulary set of keywords syntax set of rules used to construct the language s. Graphical description of the flow of processing steps not used very often somewhat old fashioned. Algorithm and flowchart are the powerful tools for learning programming. Pseudocode input the width w and length l of a rectangle calculate the area a by multiplying l with w print a.

6 average of 10 numbers iteration with a for loop 1 input x print avg sum x sum avg sum 10 0 i 1 10 1 i sum 0 begin sum 0 for i 1 to 10 input x. Be designed though the use of flowcharts or pseudocode. Steps in problem solving first produce a general algorithm one can use pseudocode refine the algorithm successively to get step by step detailed algorithm that is very close to a computer language. Pseudocode is very similar to everyday english.

The term algorithm originally referred to any computation performed via a set of rules applied to numbers written in decimal form. A flowchart is a diagram made up of boxes diamonds and other shapes connected by arrows each shape represents a step in the process and the arrows.
