Problem 1: Create 2 User Variables

Problem 1 For Problem 1 You Will Create 2 User Variables The First W

Problem 1 - For problem 1 you will create 2 user variables, the first will ask the user a minimum value, the second will ask the user a maximum value and finally you will create an fprintf statement that says... “### is a random variable between ### and ###.”

Problem 2 - On average people in Las Cruces spend between 12-16% of their annual income on entertainment. Create a variable that asks the user what their MONTHLY income is and have an fprintf statement that says... “With a monthly income of ### a Las Cruces resident would spend between ### and ### on entertainment.”

Problem 3 – The atomic weight of carbon is 12.011, hydrogen is 1.008, and oxygen is 15.999. Ask the user how many molecules of glucose they want the atomic weight of. Then your fprintf statement should say...

Understanding fundamental programming concepts such as user input, variable declaration, and output formatting is essential for developing effective and interactive applications. The three problems outlined above serve to reinforce these core ideas through practical implementation. Each problem emphasizes different aspects of user interaction and data processing, providing valuable hands-on experience that can be applied in diverse programming contexts.

Problem 1: Creating User-Defined Variables and Generating Output

The first problem tasks students with creating two user input variables, specifically designed to accept minimum and maximum values. These variables are intended to represent the bounds of a range for a particular random variable. After capturing these inputs, the program must output a sentence that explicitly states the range as determined by the user. This exercise not only introduces input handling and variable assignment but also emphasizes the importance of formatted output using fprintf or similar functions.

In practical terms, this could be implemented in MATLAB, C, or similar programming languages. For example, in MATLAB, the code might look like this:



minVal = input('Enter the minimum value: ');


maxVal = input('Enter the maximum value: ');


fprintf('%f is a random variable between %f and %f.\n', rand, minVal, maxVal);

Here, 'rand' generates a random number between 0 and 1; the focus remains on capturing user input and displaying the range succinctly. The key takeaway is understanding how to incorporate user inputs into output statements effectively, setting a foundation for more complex interactions later in programming education.

Problem 2: Calculating Expected Expenditure Based on Income

The second problem integrates statistical reasoning with user interaction by exploring spending habits. It states that residents of Las Cruces spend approximately 12-16% of their annual income on entertainment. To simulate this, students must create a variable to solicit the user's monthly income via input. Following this, the program computes the lower and upper bounds of entertainment spending based on the specified percentages and displays the results in a formatted message.

For example, in MATLAB, the implementation might look like:



monthlyIncome = input('Enter your monthly income: ');


lowerSpend = monthlyIncome * 0.12;


upperSpend = monthlyIncome * 0.16;


fprintf('With a monthly income of %.2f, a Las Cruces resident would spend between %.2f and %.2f on entertainment.\n', monthlyIncome, lowerSpend, upperSpend);

This approach reinforces understanding of simple percentage calculations, user input collection, and dynamic output creation, demonstrating how programming can model real-world financial scenarios.

Problem 3: Calculating Atomic Weight of Glucose Molecules

The third problem explores chemical computations by asking the user for the number of glucose molecules they want to analyze. Given the atomic weights of carbon, hydrogen, and oxygen, the program should calculate and report the total atomic weight of the specified number of glucose molecules. This introduces learners to the concept of molecular formulas, multiplication for scaling molecular weights, and formatted output for presenting scientific data.

Sample implementation in MATLAB could be:



numMolecules = input('Enter the number of glucose molecules: ');


atomicWeightC = 12.011;


atomicWeightH = 1.008;


atomicWeightO = 15.999;


molecularWeightGlucose = (6  atomicWeightC) + (12  atomicWeightH) + (6 * atomicWeightO);


totalWeight = numMolecules * molecularWeightGlucose;


fprintf('The total atomic weight of %d glucose molecules is %.2f.\n', numMolecules, totalWeight);

This problem enhances understanding of basic chemical calculations, unit conversions, and presentation of scientific data via programming. It illustrates how code can be utilized to perform practical scientific computations efficiently, facilitating learning in both chemistry and programming disciplines.

Conclusion

Each of these programming exercises emphasizes core skills such as capturing user input, performing calculations, and displaying formatted output, which are fundamental to building interactive applications. Practicing these skills prepares students to develop more complex systems and promotes logical thinking, problem-solving, and technical proficiency. As programming increasingly becomes integral to scientific, financial, and engineering fields, proficiency in these foundational concepts remains essential for aspiring developers and scientists alike.
