Spiral Matrix Generation

The following program generates matrices in a clockwise spiral pattern based on user input for the size and corner values. It consists of three main components: the caracolMatrix function, the checkRange function, and the main function. This project is a homework realized for Compu I

caracolMatrix Function

The caracolMatrix function takes two parameters, n and corner, and generates a matrix in a clockwise spiral pattern.

Parameters

  • n: An integer representing the size of the matrix.
  • corner: An integer representing the starting corner of the matrix (values 1-4).

Algorithm

  1. Initialize the matrix array with zeros.
  2. Set the initial values of e, x, and y based on the corner parameter.
  3. Set the initial step value based on the current direction.
  4. Iterate i from 1 to n * n:
    • Set the value of matrix[e] to i.
    • If the next element (matrix[e + step]) is zero and the current position x is less than n, move to the next element in the current direction.
    • Otherwise, update the direction (y) and the step value (step) based on the next direction.
    • Move to the next element in the updated direction.
  5. Print the elements of the matrix array in a tabular form, with each row separated by a newline.

checkRange Function

The checkRange function checks if the given values n and a are within specified ranges.

Parameters

  • n: An integer representing the size of the matrix.
  • a: An integer representing the corner value.

Return Value

  • 1 if both n and a are within the specified ranges.
  • 0 otherwise.

main Function

The main function is the entry point of the program. It handles user input, validation, and calling the necessary functions to generate and print the matrices.

Algorithm

  1. Read the value of size from the user.
  2. Initialize the nMatrix and cornerMatrix arrays to store the sizes and corner values, respectively.
  3. Iterate i from 0 to size - 1:
    • Read the values of n and corner from the user and validate them using the checkRange function.
    • If the values are not valid, prompt the user to enter correct values.
    • Store the valid values in the nMatrix and cornerMatrix arrays.
  4. Iterate i from 0 to size - 1:
    • Call the caracolMatrix function with the corresponding size and corner values from the arrays.
    • Print three newline characters to separate the matrices.

This program allows users to generate matrices in a clockwise spiral pattern by providing the size and corner values. The caracolMatrix function implements the spiral pattern algorithm, while the checkRange function validates the input ranges. The main function handles user input, validation, and calls the necessary functions to generate and print the matrices.
