Pure virtual function:

• A pure virtual function is a virtual function that is required to be implemented by a derived class if derived class is not abstract.

• COCOMO prescribes a three stages process for project estimation
• In the first stage, an initial estimate is arrived at; Over the next two stages, the initial estimate is refined to arrive at a more accurate estimate
• COCOMO uses both single and multivariable estimation models at different stages of estimation
• The three stages of COCOMO estimation technique are basic COCOMO, intermediate COCOMO, and complete COCOMO

Note:

COCOMO stands for Constructive Cost Estimation Model.
