从键盘输入一个字符串、一个整数和一个实数，将其写入文件f1.txt中，再用读字符方式从此文本文件中逐个读出并显示在屏幕上
从键盘输入一个字符串、一个整数和一个实数，将其写入文件f1.txt中，再用读字符方式从此文本文件中逐个读出并显示在屏幕上
程序代码：#include<iostream>
#include<fstream>
using namespace std;
int main(void)
{
char buf[1024];
int value;
double number;
ofstream ofs;
ofs.open("test.txt");
if(ofs.is_open()){
cout << "opening file success!" << endl;
}
cout << "Enter your string :";
cin.getline(buf, 100);
ofs << buf << endl;
cout << "Enter your int :";
cin >> value;
ofs << value << endl;
cout << "Enter your double :";
cin >> number;
ofs << number << endl;
ifstream ifs;
ifs.open("test.txt", ios::in);
if(ifs.is_open()){
cout << "opening file success!" << endl;
}
cout << "Reading the file:" << endl;
ifs >> buf;
cout << buf << endl;
ifs >> value;
cout << value << endl;
ifs >> number;
cout << number << endl;
return 0;
