把这些垃圾从我的向量中删除

Question

我想消除 vector上的垃圾。 下面的 synsAux。 它应该打印：

1 
7
7
1

我在第一个和第三个数字之前得到了额外的 2，为什么？ 这 2 是空格的 ascii 值还是什么？ 我如何避免读取它？

这是运行程序所需的字典文件：

dictionary.txt
1 cute
2 hello
3 ugly
4 easy
5 difficult
6 tired
7 beautiful
synonyms
1 7
7 1
antonyms
1 3
3 1 7
4 5
5 4
7 3

你在这里打印两个：

cout<<synsAux.size();
