Reading “integer” size bytes from a char* array.

Question

I want to read sizeof(int) bytes from a char* array.

a) In what scenario\'s do we need to worry if endianness needs to be checked?

Answer 1

You shouldn't need to worry about endianess unless you are reading the bytes from a source created on a different machine, e.g. a network stream.

Given that, can't you just use a for loop?

void ReadBytes(char * stream) {
    for (int i = 0; i < sizeof(int); i++) {
        char foo = stream[i];
        }
    }
 }

Are you asking for something more complicated than that?
