c++ - How to convert endianness- as array of bits -


i'm looking convert value little-endian big-endian (and vice versa). have value expressed array of bits, rather single integer. how can implement endianness swap function?

i'm not c++ person, i'm going generically.

to convert big endian little endian reverse bytes. is, segment of 8 bits.

so if have array of n bytes (pseudocoded here):

bool bits[8*n];

you this:

for(int = 0; < n/2; i++) {     for(int j = 0; j < 8; j++) {         bool tmp = bits[8*i+j];         bits[8*i+j] = bits[8*(n-i-1)+j];         bits[8*(n-i-1)+j] = tmp;     } }

in comments, mentioned "bits" pointers expressions evaluated correct bits later. changing order of pointers in fashion yield correct change of endian-ness when later bits.
