C++切分超長文本__C++

用於將某些超長文本進行等段分割，以便某些測試型軟體（如matlab）使用

#include#include#include#includeusing namespace std;string num2str(int i){stringstream s;s << i;return s.str();}int main(){string buff, OutputFileName, stri; //讀入字串ifstream infile;ofstream outfile;int position, i, cnt, step, n,j;char c;cout << "Input file name: " << endl;cin >> buff;infile.open(buff.c_str());//總行數,每段行數cnt = 0;step = 10000;if (!infile)cout << "error" << buff << endl;//統計讀入檔案長度while (getline(infile, buff)){cnt++;}cout << cnt << endl;//cnt = 442892;n = (cnt / step) + 1;cout << n << " files totally"< cnt)step = cnt - (i-1)*step;//讀取step行字元for (j = 0; j < step; j++){getline(infile, buff);outfile << buff << endl;}outfile.close();}infile.close();cin >> n;return 0;}
