小编Nar*_*ggi的帖子

我是 Spring MVC 的新手。我正在编写一个简单的 maven web 项目，以便在调用时在视图中显示一个 hello world。除此之外，我正在使用 apache tomcat 7。
我正在关注这个
控制器正在被调用，我能够设置和打印模型映射。

我正在使用gcc(Ubuntu 4.8.2-19ubuntu1)4.8.2
我正在编写一个非常简单的脚本来将字符串作为输入并使用一些自定义消息进行打印.第一个用户输入T(没有时间取字符串),然后通过fgets输入.
.我用这个和这个作为参考.
我得到一个非常奇怪的输出,即fgets正在添加一些额外的新行甚至循环不能正常工作T = 2它只询问输入一次.
任何人都可以解释我的代码片段有什么问题.提前致谢!

#include<stdio.h>
#include<string.h>
int main()
{
  int T;
  scanf("%d",&T);

 while(T--){
    char str[100]={""};
    int i;
    printf("Hello\n");
    fgets(str,80,stdin);
    i = strlen(str)-1;
    if(str[i]=='\n')
    str[i]='\0';
    printf("World\n");
    printf("%s\n",str);

  } 
   return 0;

} 

请参阅T = 2的图像参考,即使T = 2,它只接受一次字符串,打印语句的顺序也不符合预期.
