C语言初识指针

C语言初识指针

1.*为取值操作符，&为取址操作符。例： i=3,i的地址为2000

若pointer_1 = &a 则 & *pointer_1 = &a;

int * i_pointer;

i_pointer =  &i;

则：* i_pointer = 3;

i_pointer = 2000;

#inlcude<stdio.h>

int main()

{

int a,b;

int *pointer_1,*pointer_2;

a = 100;

b = 10;

pointer_1 = &a;

pointer_2 = &b;

printf("%d,%d\n",a,b);

printf("%d,%d\n",*pointer_1,*pointer_2);

return 0;

}
