[C] Pointer에 관하여

잊을만하면 자신의 존재감을 일깨워주는 존재 Pointer.

#include <stdio.h>

int main()
{
    unsigned int test[] = {1,2,3};
    unsigned int test2[] = {1,2,3};
    unsigned int *ptr = test;
    unsigned int **pptr = &ptr;
    printf("test address:\t%x, ptr value:\t%x, exp ptr as pptr:\t%x\r\n",  
        &test, ptr, *pptr);
    printf("ptr address:\t%x, pptr value:\t%x\r\n", &ptr, pptr);
    ptr = test2;
    printf("test2 address:\t%x, ptr value:\t%x, exp ptr as pptr:\t%x\r\n", 
            &test2, ptr, *pptr);
    return 0;
