c语言测int32的最大阶乘和int64的最大阶乘

代码：

#include 

int main() {
  __int64_t MaxInt32 = __INT32_MAX__;
  __int64_t sum32 = 1;

  
  for (__int64_t i = 1;; i++) {
    if (sum32 * i > MaxInt32)
      break;
    sum32 *= i;
  }

  __int128_t MaxInt64 = __INT64_MAX__;
  __int128_t sum64 = 1;

  
  for (__int128_t i = 1;; i++) {
    if (sum64 * i > MaxInt64)
      break;
    sum64 *= i;
  }
  printf("%d %ldn", (__int32_t)sum32, (__int64_t)sum64);

  return 0;
}
