Re: [Dev-C++] Character variables

[Per W. <pw...@ia...>]

short s = 'ab';
int i = 'abcd';

given that int is 4 byte.

But a lot of compilers will give you warnings, since it you can't be sure
if memcpy(buf,&s,sizeof(s)) will give you
  buf[0] = 'a', buf[1] = 'b';
or
  buf[0] = 'b', buf[1] = 'a';

In short - be very careful about using this feature. One place where it's
elegant to use is if you are reading a tagged file, where each tag is
4-byte long:
char *buf;

int tag = 0;
for (i = 0; i < 4; i++) {
    tag = (tag << 8) | *buf++;
}

switch (tag) {
    case 'STRT': ...; break;
    case 'HEDR': ...; break;
    case 'DATA': ...; break;
    case 'ENDF': ...; break;
}

If there are a lot of tags, the result is a very fast matching of the
tags.
