Flowchart else if

问题:

I'm making a flowchart a for an algorithm, and came into some problem for an else if statement.

For an if-statement such as this one

if (something) {}
else if (something) {}
else {}

How would the else if statement look like in a flowchart diagram?

http://code2flow.com allows you to create such flowcharts from code.

Here is the DRAKON version of this:

if (case1) {outcome1}
else if (case2) {outcome2}
else {outcome3}

Alternatively, it could look like this:

回答3:

You could diagram this as two separate if statements.

I don't know if this is the "standard" method, but that's what I do.

回答4:

For starters, let's recast the statement.

if (case1) {outcome1}
else if (case2) {outcome2}
else {outcome3}

Does it not flow thus?

case1? yes --> outcome1

no --> case2? yes --> outcome2

no --> outcome3
