Cohen-Sutherland Line Clipping Algorithm
What is the Cohen-Sutherland Algorithm?
The Cohen–Sutherland algorithm is a line clipping method used to clip a line segment against a rectangular clipping window. It divides the area around the window into regions and assigns a 4-bit region code (Outcode) to each endpoint of the line.
Algorithm Steps
Assign 4-bit codes to each endpoint. Each bit represents a position relative to the window:
- Bit 1: Top
- Bit 2: Bottom
- Bit 3: Right
- Bit 4: Left
For example:
0000→

Time Lags Affecting Fiscal Policy Implementation
Fiscal policy suffers from three main lags: recognition, implementation, and impact lags. It takes time to recognize economic problems, approve policies through political processes, and for the policy to affect output, employment, and inflation. These delays can significantly reduce the effectiveness of fiscal policy.
Factors Influencing the Multiplier Effect
Factors Decreasing the Multiplier Effect
Two primary factors reduce the multiplier effect:
- High
Public Contract Guarantees and Supplier Registration Rules
Exclusion of Supplier Registration

C# Programming Fundamentals: Arrays, Loops, and Decisions
Life Expectancy Analysis with Parallel Arrays
This exercise demonstrates the use of parallel arrays to store and process life expectancy data by gender.
Instructions
- Create four parallel arrays containing the life expectancy data as shown in Table 1.
- Iterate through the parallel arrays to count and display a list of country names where the life expectancy for both genders exceeds 80 years.
- Prompt the user to input a country code.
- Use a loop to display the country name and life expectancies for males,
Ethical Principles for Business: Theories, Society, and Law
Key Theories of Ethics and Their Application
Utilitarianism
Definition: The ethical theory that suggests the best action is the one that maximizes overall happiness or well-being for the greatest number of people.
Application: In business, this could mean making decisions that benefit the majority of stakeholders, such as providing affordable products to a large customer base, even if it means lowering profit margins.

Goldin: Education, Technology, and Inequality
The High School Movement initially yielded large returns to education, which decreased later as more people became educated.
The economic landscape is characterized as a “Race between Education and Technology”:
- Education represents the supply of skills.
- Technology represents the demand for skills.
If technological advancement outpaces educational attainment (Tech > Edu), inequality increases. The return to education is the equilibrium price determined
