c指针点滴5-指针变量计算

//接口dll
_declspec(dllexport) void  go()
{
    char *p1;
    int  *p2;
    p1 = (char*)0x30fa83;//每次运行exe的时候输出地址值不同
    *p1= 'c';
    p2 = (int *)0x30fa74;
    *p2 = ;

}

    char ch = 'A';
    int num = ;
    double db = 12.5;
    char *p1 = &ch;
    int *p2 = &num;
    double *p3 = &db;
    printf("%x,%x,%x",p1,p2,p3);
    printf("\n%c,%d,%f",*p1,*p2,*p3);

    while()
