师兄们~C++怎样读TXT檔

[noobguy]

师兄们
我想我的HANGMAN里面的生字是读TXT檔的
要怎么做呢?
同学给了我一个例子
但是我做不出呢...
求各位师兄们指教小弟

我的HANGMAN

#include <stdafx.h>
#include <stdio.h> 
#include <cstdlib> 
#include <ctime> 
#include <iostream> 
#include <string> 
#include <algorithm>                             


using namespace std; 


int main() {
	printf("Hangman game :-)\n-----------------------\n");
	printf("How to play:\n"
		"the challenger will put a word in h.txt in the same\n"
		"directory as this application. After that run the program!\n\n");
	ifstream fp("h.txt");
	char s[20];fp >> s;
	int n=strlen(s);int i,chances=10;char c,dd=s[0];
	char a[20];char d[26];d[0]=0;int j=0,flag=0;
	for(i=0;i<n;i++)a[i]='_'; a[n]='\0';
	while(chances > 0) {
		flag=1;
		for(i=0;i<n;i++)printf("%c ",a[i]);
		for(i=0;i<n;i++) {
			if(a[i] != s[i]) flag=0;

读TXT檔的HANGMAN[不完整]

[nullah]

ifstream fp("h.txt");//楼主这不是写了的嘛 用文件流绑定到txt文件 就OK
char s[20];
fp >> s;//在这里写

//同样输出流
ofstream b("h.txt");

[就呆在云上]

这样，把你定义文件fp的地方修改一下：

    ifstream fp("h.txt");
	string wordBank[6];
	int i = 1;
	while(i <= 6) {
		fp >> wordBank[i];
		i++;
	}

就是从文件里面读书你要的单词了，试试

[nullah]

#include <iostream>
#include <string>
#include <fstream>
using namespace std;
int main()
{
	string s;
	ifstream dict("aaa.txt"); 
	//读出文件中的单词
	while (dict>>s) 
	{
		cout << s <<"\n";
	}
	dict.close();

	fstream out("aaa.txt",ofstream::app);
	s = "xxxx";
	out << s << endl;//往文件中写入xxxx

}

师兄们
这样对吗?
但是好像有问题的样子
谢谢

[Quote=引用 2 楼 ztz0223 的回复:]

这样，把你定义文件fp的地方修改一下：

C/C++ code ifstream fp("h.txt");
string wordBank[6];
int i = 1;
while(i <= 6) {
fp >> wordBank[i];
i++;
}



就是从文件里面读书你要的单词了，试试

up，这样就可以了，楼主可以试试
