Introduction to Programming CS1325 – Spring 2017 Assignment #1 – Basic C posted: February 1st, 2017 due date: February 13th, 2017 – 10:00pm

In this assignment, you will write small C programs. Each program should be submitted as a standard C source code file, either separately or zipped together. The programs must follow class formatting and commenting rules, including headers with author’s name, class, date, and description. Proper indentation, commenting end braces, and aligned code are required.

Program 1: For each of the three sub-parts (a to c), you will prompt the user for an integer n and a character ch. The program will display output based on these inputs:

• 1.a): Display a pattern of stars with increasing odd counts per line, e.g., for n=5 and ch='': , , **, etc.
• 1.b): Display n stars per line with increasing spaces between stars in each subsequent line.
• 1.c): Display a pattern combining sequence of numbers and stars in a specific order for n=5, e.g., 1, 2, 3, 4, 5*, etc.

Program 2: Write a program to evaluate a polynomial function (order 1 to 5) over an interval [xmin, xmax], and display a table of x and f(x) values:

• The program prompts for the function’s order. If invalid (not 1-5), display error and end.
• For valid order, prompt for coefficients based on the order.
• Ask for xmin and xmax. If xmax ≤ xmin, display error and end.
• Calculate the increment dx = (xmax - xmin) / 10.
• Display a table with 11 rows, starting at xmin, ending at xmax, with x and f(x) computed accordingly, formatted with two decimal places for f(x).

Optional Extra: Include plots of f(x) over range [-13,13] for each valid function order, using coefficients you select, using Octave or SciLab if MATLAB is unavailable.

Be sure to document variables, constants, and include a report explaining these. The assignment covers basic C programming skills including expression evaluation, operators, flow control, and file formatting.

Introduction

The assignment involves writing small C programs focused on fundamental programming concepts such as loops, conditionals, user input/output, and function evaluation. It provides an opportunity to practice clean coding standards, including proper commenting, indentation, and program documentation. The two primary programs encompass pattern printing and polynomial evaluation over a specified interval, each requiring logical implementation and attention to detail.

Program 1: Pattern Printing

The first program aims to generate three different patterns based on user inputs. These patterns serve to enhance understanding of nested loops, conditional statements, and formatted console output in C. The key is to prompt users accurately and display outputs that exhibit varying use cases of loops: increasing odd stars, variable spacing between characters, and sequence-based complex patterns.

Program 2: Polynomial Evaluation

This program introduces polynomial computations of varying degrees (from linear to quintic). It requires user input validation, coefficient handling, and calculations involving power functions, such as pow() from math.h. The critical components include validating the function order, ensuring the interval limits are correct, computing function values efficiently, and displaying a well-formatted table. An optional graphical plot encourages integration with numerical tools like Octave or SciLab for visual analysis, emphasizing interdisciplinary skills.

Implementation Strategy

For program 1, nested loops with conditional logic are essential. For example, printing pattern 1.a involves printing odd numbers of stars with consuming increment logic. Pattern 1.b involves nested loops with increasing spaces, requiring careful spacing logic. Pattern 1.c involves nested sequences, combining counters and conditionals.

Program 2 requires validation of inputs to ensure function orders are within 1-5; coefficients are captured based on the order; then, linspace logic is used to generate x-values over the interval; subsequent function evaluation uses pow() for polynomial terms. The resulting table must be formatted precisely with two decimal places, demanding formatted printing functions like printf().

Including graphical outputs involves exporting data points to a plotting tool, which is optional but highly recommended for deeper comprehension. Proper documentation of variables, constants, and logic enhances clarity and maintainability.

Conclusion

This assignment integrates core C programming skills with practical problem-solving in pattern generation and mathematical computation. Attention to detail, validation, and formatting are priorities. Extending to graphical plots fosters interdisciplinary approach and enhances comprehension of function behaviors across specified ranges.
