UC知道c++读取txt文档问题
来源：百度知道 编辑：UC知道 时间：2024/06/09 06:12:28
想读取一篇英文文章中的单词，输出到屏幕上，文章中有空格，标点，什么办法才能分辨出是不是一个单词？txt读取字符的时候，空格是不是自动跳过？
谢谢各位了！！！！！！

cout << "不能打开" << endl;
return 1;

char ch;
file1 >> ch;

ch = ch -'a' + 'A';

if( (ch < 'A') && (ch > 'Z') && (ch< 'a') && (ch > 'z') )

按我的思想：
char c;
file >> c;
if ( !isalpha(c) ) // 如果不是字母
vector.push_back(word);
// 还有，你不必用字符数组，直接用string就可以了。string.push_back.
只需要这么点代码就可以，您的代码太啰嗦啦！
#include<iterator>
#include<fstream>
#include<string>
#include<vector>
#include<cctype>
using namespace std;
int main()
{
string word; vector<string> v; ifstream ifs("in.txt");
for (int c; ifs; )
if (isalpha(c = ifs.get())) word += c;
else if (!word.empty()){ v.push_back(word); word = ""; }
copy(v.begin(), v.end(), ostream_iterator<string>(cout, "\n"));
}
