我编写了一个代码,我试图读取一个bmp文件并将其写入另一个文件。当我尝试编写它时,输出文件会创建,但它不会打开。这是我的代码
#include<iostream>
#include<fstream>
using namespace std;
//int writeFile(string content);
int main() {
ifstream myReadFile;
ofstream myWriteFile;
myReadFile.open("D:/MIT_Database/barbara_gray.bmp");
myWriteFile.open("D:/MIT_Database/barbara_graywrite.bmp");
char output[100];
string content;
if (myReadFile.is_open()) {
while (!myReadFile.eof()) {
getline( myReadFile, content );
cout<<content;
// myReadFile >> output;
for(int i=0;i<content.length();i++)
{myWriteFile<<content[i];}
// myWriteFile<<content<<'\n';
myWriteFile<<'\n';
}
}
myReadFile.close();
myWriteFile.close();
return 0;
}
答案 0 :(得分:1)
fstream in(&#34; test.bmp&#34;,ios :: binary | ios :: in);
fstream out(&#34; new.bmp&#34;,ios :: binary | ios :: out);
char c;
while(!in.eof()){
C = in.get();
out.put(C); }
in.close();
out.close();
