C語言自學攻略-深入剖析陣列名與指標在sizeof()下的輸出

探討sizeof()下的輸出結果:

#include <stdio.h>

int main() {
    int b[]={10,20,30};
    int *p = b;
    printf("%d\n",sizeof(b));
    printf("%d\n",sizeof(p));
    printf("%d\n",sizeof(b[0]));
    printf("%d\n",sizeof(&b));
    printf("%d\n",sizeof(b+1));
    printf("%d\n",sizeof(p+1));
    printf("%d\n",sizeof(&b+1));
    printf("%d",sizeof(*p+1));
    
    return 0;
}
