RecurrenceSequence.cpp

This page explains each function in your RecurrenceSequence class. For every method, you’ll learn what it does and how it works in simple steps before seeing the full code.

You will need to use the assert library in your code so make sure to include this near the top of your file: #include <assert.h>

RecurrenceSequence() - Default constructor

This function runs when you create a new object with no input values. It sets all internal numbers to zero and sets the sequence pointer to nullptr, meaning the array doesn't point to anything yet.

RecurrenceSequence::RecurrenceSequence() {
    seq = nullptr;
    a = b = p = q = length = 0;
}

RecurrenceSequence(int aVal, int bVal, int pVal, int qVal, int len) - Parameterized constructor

This function runs when you want to create a sequence with specific values. It:

• Stores the given values (a, b, p, q, and length)

• Creates space in memory for the full sequence

• Calls generateSequence() to calculate and fill in the array

RecurrenceSequence::RecurrenceSequence(int aVal, int bVal, int pVal, int qVal, int len) {
    a = aVal;
    b = bVal;
    p = pVal;
    q = qVal;
    length = len;
    seq = new int[length];
    generateSequence();
}
