What are some interesting C programming coding challenges?

Here are a few interesting C programming challenges you can try:

1. Implement a simple calculator.
2. Create a program to find the factorial of a number using recursion.
3. Write a program to sort an array using bubble sort.
4. Develop a program to check if a string is a palindrome.
5. Create a program that counts the number of vowels in a given string.

Can you explain how to implement the factorial challenge?

Sure! To implement the factorial challenge using recursion, you can define a function that calls itself. Here's a simple example:

#include <stdio.h>

int factorial(int n) {
    if (n == 0) return 1;
    return n * factorial(n - 1);
}

int main() {
    int number;
    printf("Enter a number: ");
    scanf("%d", &number);
    printf("Factorial of %d is %d\n", number, factorial(number));
    return 0;
}

What are some common mistakes to avoid when coding in C?

Some common mistakes to avoid in C programming include:

1. Forgetting to include necessary header files.
2. Not initializing variables before use.
3. Mismanaging memory allocation and deallocation.
4. Off-by-one errors in loops.
5. Not checking the return values of functions.

Can you suggest resources for improving my C programming skills?

Absolutely! Here are some great resources:

1. "The C Programming Language" by Kernighan and Ritchie.
2. Online platforms like LeetCode and HackerRank for coding challenges.
3. TutorialsPoint and GeeksforGeeks for tutorials and examples.
