About MATLAB

MATLAB is a programming platform designed specifically for engineers and scientists.

About C++

C++ is a general-purpose programming language created by Bjarne Stroustrup as an extension of the C programming language, or "C with Classes".

Palindrome Check Example: MATLAB vs C++

Palindrome Check in MATLAB

function result = isPalindrome(str)
    clean = lower(regexprep(str, '[^a-zA-Z0-9]', ''));
    result = isequal(clean, fliplr(clean));
end

% Example usage
disp(isPalindrome('A man, a plan, a canal: Panama')) % true
disp(isPalindrome('race a car')) % false

Palindrome Check in C++

#include <iostream>
#include <string>
#include <algorithm>
using namespace std;

bool isPalindrome(string str) {
    string clean;
    // Keep alphanumeric chars and convert to lowercase
    for(char c : str) {
        if(isalnum(c)) {
            clean += tolower(c);
        }
    }
    
    string reversed = clean;
    reverse(reversed.begin(), reversed.end());
    return clean == reversed;
}

int main() {
    cout << boolalpha;
    cout << isPalindrome("A man, a plan, a canal: Panama") << endl; // true
    cout << isPalindrome("race a car") << endl; // false
    return 0;
}

Bubble Sort Example: MATLAB vs C++

Bubble Sort in MATLAB

function sorted = bubbleSort(arr)
    n = length(arr);
    for i = 1:n
        for j = 1:n-i
            if arr(j) > arr(j+1)
                temp = arr(j);
                arr(j) = arr(j+1);
                arr(j+1) = temp;
            end
        end
    end
    sorted = arr;
end

arr = [64, 34, 25, 12, 22, 11, 90];
disp(bubbleSort(arr))

Bubble Sort in C++

#include <iostream>
#include <vector>
using namespace std;

void bubbleSort(vector<int>& arr) {
    int n = arr.size();
    for(int i = 0; i < n; i++) {
        for(int j = 0; j < n - i - 1; j++) {
            if(arr[j] > arr[j + 1]) {
                swap(arr[j], arr[j + 1]);
            }
        }
    }
}

int main() {
    vector<int> arr = {64, 34, 25, 12, 22, 11, 90};
    bubbleSort(arr);
    
    for(int num : arr) {
        cout << num << " ";
    }
    return 0;
}
