Greetings,

I am interested in doing this project for you. I am unsure exactly what you want as you have just pasted source code in. But I'm guessing that you need the function insertElement() implemented into this source code? Is this correct.

If you are interested in me doing this project for you then please reply to this, and send me the source code files, and I can post a bid for you and have the project done quickly and properly for you.

Kind Regards,

Michael Green

A bid from mulgar for $15 (USD)...
Greetings SAN_30000,

From your comments and the source code that you have provided I am guessing that you require the function insertElement() to be implemented. I can do this for you and test to make sure that all the code works properly and functions as a matrix implemented as a list.

Any information such as specifications or internet links (to subject sites) that you could provide before or on accepting my bid to clarify things would be appreciated. If you provide me with more information I may decide that the project is easier or won't take long and then can offer you a cheaper bid.

Regards,

Michael Green

  • I will complete the project exactly according to given specifications quickly well before due time, and it will be very neat and well commented so you and other can understand it easily.
