应该是没有找到memset的函数声明，这是一个c函数，在这个头文件中有定义，在程序中加上这个头文件试试。
错误原因主要有：1、C语言是大小写敏感的，注意一些函数和关键字的大小写，如：If和if的区别2、变量的名称错误3、调用的库函数没有头文件，如：inportb/outportb等。下面的程序可以编译，但是连接时出现库函数没有说明的问题，请添加inportb/outportb对应的头文件！

C语言菜鸟求高手解答...
第一个问题只能说是一个判定条件，不知道你要的结果是什么。。2.m++>5这个判定是先取值后运算，m=5>5这个是不成立的，所以结果为假，然后m自增m=6,接着运行else printf("%d\\",m--);同样先取值运行，m=6所以输出6，之后再自减m=5但这是没有输出的，如果运行这个 main(){ int m=5;if(m++>5) printf("%d\\n",m

c语言有一道题不会做,求高手解,最好分析一下。
答案是：C 因为scanf("%c%c",&a,&b);接收的是1和2，在输入后按了“回车”这个回车符会传递到下一句，也就是：c=getchar(); ，这样 c 赋值为回车符了；d=getchar(); 接着就是这句，你输入34的时候，d 只接收单个字符，也就是 3 ；所以最后的输出是：12 3 ...
