程序1:
#include <stdio.h>
char ga[] = "abcdefghijklm";
void my_array_func(char ca[10]) {
printf("%#x, %d\n", &ca, sizeof(ca));
printf("%#x\n", &(ca[0]));
printf("%#x\n", &(ca[1]));
printf("%#x\n\n", ++ca);
}
void my_poiner_func(char *pa) {
printf("%#x, %d\n", &pa, sizeof(pa));
printf("%#x\n", &(pa[0]));
printf("%#x\n", &(pa[1]));
printf("%#x\n\n", ++pa);
}
int main(void) {
printf("%#x\n", &ga);
printf("%#x\n", &(ga[0]));
printf("%#x\n\n", &(ga[1]));
my_array_func(ga);
my_poiner_func(ga);
return 0;
}
运行结果:
0x804987c
0x804987c
0x804987d
0xff95b040, 4

参考Passing an array as an argument to a function in C。
程序2:
#include <stdio.h>
int main(void) {
// your code goes here
int array[5];
printf("%p, %d\n", array, sizeof(array));
printf("%p, %d\n", &array[0], sizeof(&array[0]));
printf("%p, %d\n", &array, sizeof(&array));
printf("%p\n", array + 1);
printf("%p\n", &array[0] + 1);
printf("%p\n", &array + 1);
return 0;
}
运行结果:
