int main()
{
  int c; 
  return 0;
} // on Intel architecture

#include <stdio.h>

int main()
{
  int c; 
  return 0;
}// on AMD architecture

Answer 1

see here:
size guarantee for integral/arithmetic types in C and C++

Fundamental C type sizes are depending on implementation (compiler) and architecture, however they have some guaranteed boundaries. One should therefore never hardcode type sizes and instead use sizeof(TYPENAME) to get their length in bytes.
