Question

I have the following code in java that I need to convert to c++ to be able to encode unsigned int.

public static int enc_uint32be( int i, byte[] dst, int di ) {
        dst[di++] = (byte)((i >> 24) & 0xFF);
        dst[di++] = (byte)((i >> 16) & 0xFF);
        dst[di++] = (byte)((i >> 8) & 0xFF);
        dst[di] = (byte)(i & 0xFF);
        return 4;
}

I am a newbie to java. I trust several experts on this forum know both languages – can someone help me with the translation.

Answer 1

It depends on the data type that you are planning on using, but if you just change:

 byte[] dst

to

unsigned char dst[]

in the function declaration, then it should behave the same (and change the byte usages in the function to unsigned char as well).
