也许这是使用 c++14 中的模板和 lambda 的更简洁的方法:
定义:
template<typename Iterator, typename Funct>
void my_assign_to_each(Iterator start, Iterator stop, Funct f) {
while (start != stop) {
*start = f();
++start;
}
}
template<typename Iterator, typename Funct>
void my_read_from_each(Iterator start, Iterator stop, Funct f) {
while (start != stop) {
f(*start);
++start;
}
}
然后主要是:
int x[10];
srand(time(0));
my_assign_to_each(x, x+10, [] () -> int { int rn{}; rn = rand(); return rn; });
my_read_from_each(x, x+10, [] (int value) { std::cout << value << std::endl; });
int common_value{18};
my_assign_to_each(x, x+10, [&common_value] () -> int { return common_value; });
my_read_from_each(x, x+10, [] (int value) { std::cout << value << std::endl; });
