Dynamic memory allocation in C (malloc, free)

[Qomplainerz]

malloc() is used to allocate memory dynamically, and free() is used to release memory when it's no longer needed.

int *ptr = (int *)malloc(sizeof(int));
if (ptr != NULL) {
    *ptr = 10;
    printf("Value: %d\n", *ptr); // Output: 10
    free(ptr); // Release memory
}
