How to save a byte type char array data to a file in c++?
提问by user1486008
I have a chartype array[100]with 100bytes stored in it. I want to write this chartype byte array to a file. How could I do this?
我有一个char类型，array[100]其中100存储了字节。我想将此char类型的字节数组写入文件。我怎么能这样做？
I am not writing to a .txtfile but some other format.
我不是在写入.txt文件，而是在写入其他格式。
Thank you.
谢谢你。

Some people object to using <cstdio>, so it is worth mentioning how one might use <fstream>:
有些人反对使用<cstdio>，因此值得一提的是如何使用<fstream>：
{
std::ofstream file("myfile.bin", std::ios::binary);
file.write(data, 100);
}
The four lines above could be combined into this single line:
上面的四行可以合并为一行：
std::ofstream("myfile.bin", std::ios::binary).write(data, 100);

No need to get complicated. Just use good old fwrite directly:
没有必要变得复杂。直接使用旧的 fwrite 即可：
FILE* file = fopen( "myfile.bin", "wb" );
fwrite( array, 1, 100, file );

Based on the (little) information you've provided, one possibility would be to write the array to the file in binary format, such as:
根据您提供的（小）信息，一种可能性是以二进制格式将数组写入文件，例如：
std::ofstream out("somefile.bin", std::ios::binary);
out.write(array, sizeof(array));
