最近在做機器學習方面的東西。用到許多到txt的操作。其中有一個txt按行拆分的代碼,留下來做筆記。
輸入:combination_test.txt(一共有32行資料)
輸出:32個單獨的txt文檔。名字分别為0.txt 1.txt 2.txt ... ...
#include <iostream>
#include <fstream>
#include <string>
#include <sstream>
using namespace std;
string s[100];
char data[2560];
void saveText(string fname,string str)
{
ofstream fout(fname.c_str());
fout<<str;
}
//讀取方式: 逐行讀取, 将行讀入字元串, 行之間用回車換行區分
//If you want to avoid reading into character arrays,
//you can use the C++ string getline() function to read lines into strings
void ReadDataFromFileLBLIntoString()
{
ifstream fin("combination_test.txt");
int i=0;
char a[25];
string str0=".txt";
while(getline(fin,s[i]) )
{
itoa(i,a,10);
string str=a+str0;
saveText(str,s[i]);
i++;
}
}
int main()
{
ReadDataFromFileLBLIntoString(); //逐詞讀入字元串
system("pause");
return 0;
}
