The symbols are self explanatory

Easier to handle complex programs

Their graphical nature makes the process of explaining an algorithm quite straight forward.

With the help of a flowchart problems can be analysed in a more effective way.

It is difficult to understand

It can be constructed quickly as compared to a flowchart.

Closer to programming code, so easier to understand.

One can write the pseudocode, then use it as a starting point or outline for writing a real code.
