2What is the major obstacle in developing programming system based on the declarative paradigm?

A major obstacle in developing programming systems based on the declarative paradigm is the need for an underlying problem-solving algorithm. For this reason, early declarative programming languages tended to be special-purpose in nature, designed for use in particular applications. For example, the declarative approach has been used for many years to simulate a system (political, economic, environmental, and so on) in order to test hypotheses or to obtain predictions. In these settings, the underlying algorithm is essentially the process of simulating the passage of time by repeatedly recomputing values of parameters (gross domestic product, trade deficit, and so on) based on the previously computed values. Thus, implementing a declarative language for such simulations requires that one first implement an algorithm that performs this repetitive function. Then the only task required of a programmer using the system is to describe the situation to be simulated. In this manner, a weather forecaster does not need to develop an algorithm for forecasting the weather but merely describes the current weather status, allowing the underlying simulation algorithm to produce weather predictions for the near future.

5Write the select query for the following statement;

• Select an employee whose ID is 123, from the employee table

*Long Question* · 1-- Draw the conceptual layout of the following structure; · Stract {char name[25]; · int age; (5 Marks)

; int Age; float SkillRating; } Employee; which says that the variable Employee is to refer to a structure (abbreviated struct) consisting of three components called Name (a string of 25 characters), Age, and SkillRating (Figure 95). Once such an aggregate has been declared, a programmer can use the structure name (Employee) to refer to the entire aggregate or can reference individual fields within the aggregate by means of the structure name followed by a period and the field name (such as Employee. Age).

3. Select

3Is there any drawback of using matching geometric characteristics technique for recognizing images in image processing? Justify your answer with two examples. (5 Marks)

This technique of recognizing images is one method used in optical character readers. It has the drawback, however, of requiring a certain degree of uniformity for the style, size, and orientation of the symbols being read. In particular, the bit pattern produced by a physically large character does not match the template for a smaller version of the same symbol, even though the shapes are the same. Moreover, you can imagine how the problems increase in difficulty when trying to process handwritten
