It's impossible to answer this question without knowing the target
platform. The C standard doesn't specify this stuff but it is usually
specified by an ABI (application binary interface) so that code produced
by different C compilers interoperates correctly. On Linux-x86_64, both
gcc and tcc give 16 for this program.

the following code

#include <stdio.h>
struct foobar{
uint16_t foo; // 4 bytes
uint64_t bar; // 8 bytes
};
int main(){
printf("%d\n", sizeof(struct foobar));
return 0;
}
prints 16, gcc 4.7 prints 12 that is the correct result. Posted in
