  • 第1题：

    有以下程序

    main()

    {char *s[]={"one","two","three"},*p；

    p=s[1]；

    printf("%c,%s\n",*(p+1),s[0])；

    }

    执行后输出结果是

    A．n，two

    B．t，one

    C．w，one

    D．O，two


    正确答案：C
    解析：本题首先定义了一个有3个元素的指针数组s，并通过赋值使s[0]指向字符串“one”，s[1]指向字符串“two”，s[2]指向字符串“three”，然后通过赋值语句“p=s[1]”，使p指向了字符串“two”，故“*(p+1)”就是字符“w”。

    DDBBCC C语言对枚举的定义规定：在枚举中声明的各个枚举元素，如果没有明确指出某个枚举元素的值，它的上一个元素存在并有明确值的情况下，这个枚举元素的值为其上一个元素的值+1。在本题中，没有明确说明枚举元素em3的值，则em3=em2+1=1+1=2，进而可知，在printf()打印函数中，要打印的数组元素是aa[3]、aa[1]、aa[2]，因此最后的打印结果应当为“DDBBCC”。
