示例#1

文件： series_test.cpp 项目： mkirsche/project-euler

TEST(series, sum_naturals_some) {
  int sum = 0; int i;
  for (i = 0; i < 100; i++) {
    sum += i;
    EXPECT_EQ(sum, sum_naturals(i));
  }
}

示例#2

文件： multiple_test.cpp 项目： mkirsche/project-euler

TEST(series, multiples_under_some) {
  int i;
  for (i = 0; i < 100; i++) {
    EXPECT_EQ(sum_naturals(i-1), multiples_under(i,1));
  }
}

示例#3

文件： solution.c 项目： NorfairKing/project-euler

  int su = sum_naturals(p);
  int suosq = sum_squares(p);
  return su * su - suosq;
}
