  • 第1题：

    *((int *)pval)／=2; ／／我想问一下,这个语法怎么理解,太复杂了 具体代码如下。

    #include "stdio.h"void half(void *pval,char type);main(){ int i=20; long l=100000; float ff=12.456; double d=123.044444; printf("%d\n",i); printf("%ld\n",l); printf("%f\n",ff); printf("%lf\n",d); half(&i,'i'); half(&l,'l'); half(&ff,'ff'); half(&d,'d'); printf("\n%d",i); printf("\n%ld",l); printf("\n%f",ff); printf("\n%lf",d); return 0; }void half(void *pval,char type){ switch(type) { case 'i': { *((int *)pval)/=2; //我想问一下，这个语法怎么理解，太复杂了 break; } case 'l': { *((long *)pval)/=2; break; } case 'ff': { *((float *)pval)/=2; break; } case 'd': { *((double *)pval)/=2; break; } } }


    *((int *)pval)/=2; 一步步讲解： 1，(int*)pval 是把pval指针强制类型转化成 int*，这时pval可看作是个指向int的指针。为了方便说明我们可以int *p = (int*)pval;以后就可以用p代替(int*)pval了。 2，*(p) /=2;也就是 *p /= 2; 这里括号可以去掉了。 /=类似+=、*=， *p /=2;就是 *p = *p/2;

  • 第2题：

    b)

    main()

    {

    union{ /*定义一个联合*/

    int i;

    struct{ /*在联合中定义一个结构*/

    char first;

    char second;

    }half;

    }number;

    number.i=0x4241; /*联合成员赋值*/

    printf("%c%c\n", number.half.first,

    mumber.half.second);

    number.half.first='a'; /*联合中结构成员赋值

    */

    number.half.second='b';

    printf("%x\n", number.i);

    getch();

    }


    正确答案：

     

    AB (0x41 对应'A',是低位；Ox42 对应'B',
    是高位）6261 (number.i 和number.half 共用一块地址空
    间）
