第13周-阅读项目4-写出下面程序的输出结果

问题及代码：

#include <iostream>   
#include <fstream>   
using namespace std;  
int main()  
 {       
    fstream outfile,infile;       
    outfile.open("data.dat",ios::out);       
    outfile<<"1111111111"<<endl;       
    outfile<<"aaaaaaaaaa"<<endl;       
    outfile<<"AAAAAAAAAA"<<endl;  
    outfile<<"**********"<<endl;  
    outfile.close();       
    infile.open("data.dat",ios::in);       
    char line[80];       
    int i=0;       
    while(!infile.eof())       
    {           
        i++;           
        infile.getline(line,sizeof(line));           
        cout<<i<<": "<<line<<endl;       
    }       
    infile.close();   
    return 0;  
}  

运行结果：

int main()  
{  
    ifstream readFile;  
    ofstream writeFile;  
    char ch;  
    readFile.open("a.txt", ios::in);  
    writeFile.open("b.txt", ios::out);  
    while (readFile.get(ch))  
        writeFile.put(ch);  
    readFile.close();  
    writeFile.close();  
    cout << "Finish!" << endl;  
    return 0;  
}

        readFile.getline(ch,100,'\n');  
        writeFile.write(ch,strlen(ch));  
        writeFile.write("\n",1);  
    }  
    readFile.close();  
    writeFile.close();  
    cout << "Finish!" << endl;  
    return 0;  
}  

运行结果：

知识点总结：
文件的读取与写入。

学习心得：

就是再次加强巩固阿，反正是新技能get了~~
