函数作为参数,相当于C++的函数指针, C#的委托
for_each函数参数:
#include <iostream>
#include <algorithm>
#include <vector>
#include "FuncParamTest.h"
#include "../../Core/ContainerUtil.h" using namespace std; void print(int elem)
{
cout << elem << ' ';
} void FuncParamTest::forEachFunc()
{
vector<int> coll; for (int i = ; i <= ; ++i)
{
coll.push_back(i);
} // print all elements
for_each(coll.cbegin(), coll.cend(), print);
cout << endl;
} void FuncParamTest::run()
{
forEachFunc();
}
运行结果:
1 2 3 4 5 6 7 8 9
