#include#include#includeusing namespace std;int main(){ofstream outdata;outdata.open("bool.txt",ios::app);//ios::app是尾部追加的意思outdata<<"其实我没有测试过。。。"<outdata.close();return 0;}
ofstream file;file.open( "a.txt", ios::out );string str = "dddddddddddddddfbbbbbbbbb";if ( file.is_open() ){ file << str << endl;}file.close();方法很多！
