About C

C is a general-purpose, procedural computer programming language supporting structured programming, lexical variable scope, and recursion, with a static type system.

About Kotlin

Kotlin is a cross-platform, statically typed, general-purpose programming language with type inference.

Palindrome Check Example: C vs Kotlin

Palindrome Check in C

#include <stdio.h>
#include <string.h>
#include <ctype.h>

int isPalindrome(export const char* str) {
    char clean[1000];
    int j = 0;
    
    // Clean the string
    for(int i = 0; str[i]; i++) {
        if(isalnum(str[i])) {
            clean[j++] = tolower(str[i]);
        }
    }
    clean[j] = '\0';
    
    // Check palindrome
    int left = 0;
    int right = strlen(clean) - 1;
    while(left < right) {
        if(clean[left] != clean[right]) return 0;
        left++;
        right--;
    }
    return 1;
}

int main() {
    printf("%d\n", isPalindrome("A man, a plan, a canal: Panama")); // 1
    printf("%d\n", isPalindrome("race a car")); // 0
    return 0;
}

Palindrome Check in Kotlin

fun isPalindrome(str: String): Boolean {
    val clean = str.lowercase().filter { it.isLetterOrDigit() }
    return clean == clean.reversed()
}

fun main() {
    println(isPalindrome("A man, a plan, a canal: Panama")) // true
    println(isPalindrome("race a car")) // false
}

Bubble Sort Example: C vs Kotlin

Bubble Sort in C

#include <stdio.h>

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

int main() {
    int arr[] = {64, 34, 25, 12, 22, 11, 90};
    int n = sizeof(arr)/sizeof(arr[0]);
    
    bubbleSort(arr, n);
    
    for(int i = 0; i < n; i++) {
        printf("%d ", arr[i]);
    }
    return 0;
}

Bubble Sort in Kotlin

fun bubbleSort(arr: IntArray) {
    val n = arr.size
    for (i in 0 until n) {
        for (j in 0 until n - i - 1) {
            if (arr[j] > arr[j + 1]) {
                val temp = arr[j]
                arr[j] = arr[j + 1]
                arr[j + 1] = temp
            }
        }
    }
}

fun main() {
    val arr = intArrayOf(64, 34, 25, 12, 22, 11, 90)
    bubbleSort(arr)
    println(arr.joinToString(" "))
}
