Introduction To Programming Cs1325 Spring 2017assignment 1 Basi

In this assignment, you will write small C programs. Each program should be submitted as a standard C source code file, following commenting and formatting rules discussed in class, including program headers with author, class, date, and description. The programs involve user input, outputs, and calculations based on specific prompts and rules. You will produce three main programs: one involving patterns with characters, another evaluating polynomial functions at intervals, and optional plotting of functions. Specific requirements include handling input validation, computing values with precision, and formatting output tables. An additional report should list all program variables, constants, and coefficients used, and optionally include plots of the functions. The assignment tests your understanding of basic C programming constructs such as loops, conditionals, input/output, and math operations, especially the use of for power calculations. It emphasizes clear coding standards, correct logic implementation, and proper documentation.

Paper For Above instruction

The following paper discusses the key aspects of the programming assignment, outlining the necessary steps, the core programming concepts involved, and best practices to successfully complete it.

The assignment requires students to develop several C programs focusing on fundamental programming skills including input handling, conditional logic, looping structures, mathematical calculations, and output formatting. The first task involves creating three different pattern display programs based on user input for a number n and a character ch. These programs demonstrate proficiency in using loops and conditionals to generate patterns such as pyramid structures, spaced star sequences, and mixed number-star sequences. Ensuring correct user input validation and output formatting is crucial for a professional and accurate presentation.

The second task involves constructing a program to evaluate polynomial functions of degree up to five over a specified interval, with variable coefficients depending on the degree. The program prompts for function order and validates it against constraints (between 1 and 5). It also takes input for the interval bounds, ensuring that xmax exceeds xmin. The program calculates function values at equally spaced points, computes these with appropriate mathematical functions, and displays results in a well-organized table. Handling edge cases like invalid input or intervals is essential, requiring the use of conditional statements to validate inputs before processing calculations.

A critical aspect of this task is the use of and the pow() function for exponentiation, which simplifies computations involving polynomial powers. The output must have a specified decimal precision, and table formatting should mimic typical tabular data displays, including headers and aligned columns. These exercises reinforce understanding of loops, arithmetic operations, and data presentation in console applications.

The optional component involves plotting the evaluated functions over a broader range, such as [-13, 13], using external tools like MATLAB, Octave, or Scilab. While not mandatory, this enhances understanding of polynomial behavior and visualization skills. The inclusion of such plots requires generating data points for multiple function degrees with chosen coefficients, then exporting the data for plotting, which encourages integration of C programming with scientific visualization software.

Overall, this assignment aims to strengthen core programming concepts, particularly in the context of mathematical computations, pattern generation, and input validation, which are essential in developing reliable, efficient, and readable C programs. Proper commenting, code organization, and adherence to class standards are emphasized to ensure that the submitted code exemplifies good programming practices.
