If you are interested in deepening your knowledge, would it be helpful if I: Explained the difference between ? Gave examples of pointer-based string manipulation ?

int num = 45; int *ptr = # // ptr now stores the memory address of num Use code with caution. Memory Visualization

Also called the dereferencing operator, this accesses the value stored at the address held by the pointer. If you are interested in deepening your knowledge,

To declare a pointer, you use the asterisk symbol (*) before the pointer name. For example:

Pointers are a fundamental concept in C programming that can be challenging to grasp at first, but with practice and patience, you'll become proficient in using them. ptr = &score

#include void swap(int *a, int *b) { int temp = *a; *a = *b; *b = temp; } int main() { int x = 5, y = 10; // Passing the memory addresses of x and y swap(&x, &y); printf("x = %d, y = %d\n", x, y); // Outputs: x = 10, y = 5 return 0; } Use code with caution.

C allows you to perform addition and subtraction on pointers. However, pointer arithmetic is relative to the size of the data type the pointer references.

#include int main() { int score = 95; int *ptr; ptr = &score; // ptr now holds the address of score printf("Value of score: %d\n", score); printf("Address of score: %p\n", &score); printf("Value stored in ptr (address): %p\n", ptr); printf("Value pointed to by ptr: %d\n", *ptr); // Modifying value via pointer *ptr = 100; printf("New value of score: %d\n", score); return 0; } Use code with caution.
