用2或3行代码将十六进制值转换为ascii [英] code in 2 or 3 lines to convert hex value to ascii

问题描述

这是我的代码

1)

Hi,

here is my code

1)

long crcVal=22271827222;

tempFile<<hex<<crcVal;

同一个crcVal，我想转换成ascii吗?
在这方面帮助我.

2)

same crcVal, i want to convert into ascii?
help me in this.

2)

long bufflength=1500;

tempFile<<bin<<bufflength // here it is not printing binary number ,some decimal value is printing in the file.

在这里我想将二进制格式的bufflength打印到文件中.

请在这方面帮助我

在此先感谢

推荐答案

您的文件流应打开以进行二进制写入.

参见 http://www.cplusplus.com/reference/iostream/fstream/fstream/ [ ^ ]

所以你应该得到这样的东西:
fstream

Your filestream should be opened for binary writing.

see http://www.cplusplus.com/reference/iostream/fstream/fstream/[^]

so you should get something like this :
fstream

filestr ("test.bin", fstream::in | fstream::out | fstream::binary);
fstream << crcVal;
