3) Edraw Max Edraw Max is a flowchart builder software that helps you to make diagrams using ready-made symbols and templates. It allows you to import your drawings to file formats such as PDF, PPT, Word, HTML, etc. Features: You can create a flowchart. When the program starts the user is prompted to insert a starting number for the countdown. Then the while loop begins, if the value entered by the user fulfills the condition n0 (that n is greater than zero) the block that follows the condition will be executed and repeated while the condition (n0) remains being true. The whole process of the previous program can be interpreted according to. As it currently stands, this question is not a good fit for our Q&A format. We expect answers to be supported by facts, references, or expertise, but this question will likely solicit debate, arguments, polling, or extended discussion. Example 2: Sum of Positive Numbers Only // program to find the sum of positive numbers // if the user enters a negative number, the loop ends // the negative number entered is not added to the sum #include using namespace std; int main int number; int sum = 0; // take input from the user cout number; while (number = 0) // add all positive numbers.

Flowchart is a diagrammatic representation of sequence of logical steps of a program. Flowcharts use simple geometric shapes to depict processes and arrows to show relationships and process/data flow.
Here is a chart for some of the common symbols used in drawing flowcharts.
Dev C 2b 2b Flowchart Example
|Start/Stop||Used at the beginning and end of the algorithm to show start and end of the program.|
|Process||Indicates processes like mathematical operations.|
|Input/ Output||Used for denoting program inputs and outputs.|
|Decision||Stands for decision statements in a program, where answer is usually Yes or No.|
|Arrow||Shows relationships between different shapes.|
|On-page Connector||Connects two or more parts of a flowchart, which are on the same page.|
|Off-page Connector||Connects two parts of a flowchart which are spread over different pages.|
Guidelines for Developing Flowcharts
These are some points to keep in mind while developing a flowchart −
Flowchart can have only one start and one stop symbol
On-page connectors are referenced using numbers
Off-page connectors are referenced using alphabets
General flow of processes is top to bottom or left to right
Arrows should not cross each other
