Phlegm originates from the lungs. It is different from the mucus that is produced in the nasal passages. A common cause of phlegm is post nasal drip which is a symptom of sinus infections, colds, flu and inhalation of irritants. The diagnosis of the underlying condition could be made from the color of the phlegm.
A flow chart is a type of diagram representing a process using different symbols containing information about steps or a sequence of events. Each of these symbols is linked with arrows to illustrate the flow direction of the process.
Unformatted text preview: Why is a flowchart useful in developing and documenting software? Why is the interactive Visual Logic flowchart program more useful than a manually drawn flowchart? Using Visual Logic, you will create computer algorithms that can be saved, edited, executed, and debugged. Flowcharts without execution are of limited value because students have no way of knowing if they are on the right track. Visual Logic flowcharts are executable, providing immediate and accurate feedback to the student, combining the benefits of a high-level language with the simplicity of the classic flowcharting tool.
