我想得到文件内容,并把每一行在数组的项目 [英] I want to get file content and put each line in item of array
问题描述
我有一个文本文件,此文件包含以下内容:
文件内容
27013。
Jake lexon。
8 Gozell St.
25/7/2013。
0.
我想将文件的内容保存到数组中,数组项如:
理论上
array [item1] = 27013.
array [item2] = Jake lexon。
array [item3] = 8 Gozell St.
array [item4] = 25/7/2013。
array [item5] = 0.
我尝试了很多,但是我失败了。 p>
编辑
使用c风格数组的原因是因为我想熟悉这两种方式 c-style数组
和向量
不是简单的方法向量
。

首先,调试器不会给我任何错误。
这是我使用的代码。
fstream fs(accounts / 27013.txt,ios :: in);
if(fs!= NULL){
char * str [100];
str [0] = new char [100];
int i = 0;
while(fs.getline(str [i],100))
{
i ++;
str [i] = new char [100];
cout<< str [i];
}
cin.ignore();
} else {
cout<< 错误。;
}
以及该代码的结果:
当您需要一个解决方案,没有矢量(我不会喜欢)
include< iostream>
#include< fstream>
using namespace std;
int main()
{
fstream fs;
fs.open(abc.txt,ios :: in);
char * str [100];
str [0] = new char [100];
int i = 0;
while(fs.getline(str [i],100))
{
i ++;
str [i] = new char [100];
}
cin.ignore();
return 0;
}
注意:假设每行长度超过100个字符(包括换行符),且您的行数不超过100行。
I have a text file, this file contain the following:
The file content
27013.
Jake lexon.
8 Gozell St.
25/7/2013.
0.
I want to save the content of file into array, each line saved in item of array like:
Theoretically
new array;
array[item1] = 27013.
array[item2] = Jake lexon.
array[item3] = 8 Gozell St.
array[item4] = 25/7/2013.
array[item5] = 0.
I tried a lot but I failed.
Edit
The reason of using c-style array is, because I want to be familiar with both ways c-style array
and vector
not the easy way only vector
.
Edit 2
Firstly the debugger doesn't give me any error. And this is the the code that I used.
fstream fs("accounts/27013.txt", ios::in);
if(fs != NULL){
char *str[100];
str[0] = new char[100];
int i = 0;
while(fs.getline(str[i],100))
{
i++;
str[i] = new char[100];
cout << str[i];
}
cin.ignore();
} else {
cout << "Error.";
}
and the result of that code :
AS YOU DEMAND A SOLUTION WITHOUT VECTORS.(Which I won't prefer at all)
#include<iostream>
#include<fstream>
using namespace std;
int main()
{
fstream fs;
fs.open("abc.txt",ios::in);
char *str[100];
str[0] = new char[100];
int i = 0;
while(fs.getline(str[i],100))
{
i++;
str[i] = new char[100];
}
cin.ignore();
return 0;
}
NOTE: This assumes that each line is no longet than 100 characters(including newline) and you have no more than 100 lines.
