#115: Mastering Pointers in C!**

Hey Coders! 👩‍💻👨‍💻

Let's dive into the world of pointers with today's challenge! 🎯


#include <stdio.h>

int main() {
// Declare an integer variable
int num = 42;

// Declare a pointer and point it to the address of 'num'
int *ptr = &num;

// Modify the value using the pointer
*ptr += 8;

// Print the updated value
printf("The new value of num is: %d\n", num);

return 0;
}


🤔 Challenge Task:
1. Understand how the pointer ptr is initialized.
2. Use the pointer to increment the value of num by 8.
3. Print the updated value of num.

💡 Hint: Remember to dereference the pointer using * to access and modify the value it points to.
