Create a structure array to store the details of the engineers working in a company. Assume that there are 3 engineers in the company, and you will store their names, area of expertise, number of years that they have been working in the company, and the number of projects that they have completed in the last three months (this one should be as a vector including the number of projects completed in each month). Assume that the last engineer's, last number of projects was asked, type the necessary lines of codes to show that data.
