请问:
printf("please enter an int:");
while(scanf("%d",&n)!=1){
   while(getchar()!='\n')   ;
   printf("input incorrect.an int again");
}
for(i=0;i<n,++i)……
中的“while(getchar()!='\n')   ;”是什么意思？里面的“getchar()”指的是n的编码值还是程序另外要求输入的字符编码值？

If I can find the answer in the books,I should not ask for help at here.I am learning this programming by myself,so I must ask others for help when I have answers.

Sorry,I konw the "'\n'",please look my answer carefully.

是啊,可是while后面是空格紧接着分号,什么意思???

哎,我也不喜欢鸟语,这位仁兄也许是看不懂我的中文提问.

大哥,你说的我都懂,可是你的回答不是我想要的啊。难道是我的表达能力有问题？？？

对，就是这个
