Initializing from array : // CPP program to initialize a vector from // array. #include <bits/stdc++.h> using namespace std; int main() { int arr[] = { 10, 20, 30 }; int n = sizeof(arr) / sizeof(arr[0]); vector<int> vect(arr, arr + n); for (int x : vect) cout...
for (int &i : myArray) { std::cout << i << ", " << std::endl; } } 1. 2. 3. 4. 5. 6. 但是当数组被传入其他函数作为变量时, 遍历循环失效 #include<iostream>void printElements(int someArray[5]) { for (int &i : someArray) { std::cout << i << ", " << std::endl...
C++ vector中实际删除元素使用的是容器vecrot中std::vector::erase()方法。C++ 中std::remove()并不删除元素,因为容器的size()没有变化,只是元素的替换。代码:std::vector::erase()函数原型:iterator erase (iterator position);//删除指定元素 iterator erase (iterator first, iterator last);//...

为了克服array必须事先宣告大小的不便,STL和.NET都有解决的方式,在STL的container当中,速度最快的就是std::vector,而.NET当中就是ArrayList,所以我想测试在同样的程序中,若使用unmanaged 的std::vector是否会比managed ArrayList快。 1 /* 2 (C) OOMusou 2006http://oomusou.cnblogs.com ...

使用vector.insert將array轉vector,雖然也是一行完成,但不是那麼直觀,建議還是用constructor的方式將array轉std::vector。 1/**//* 2(C) OOMusou 2006 3 4Filename : ArrayToVectorByInsert.cpp 5Compiler : Visual C++ 8.0 6Description : Demo how to convert array to vector by vector.insert ...

I personally don't find that array notation to be particularly useful. You might as well just size it with a constant and avoid the error prone sizeof functions. What you have coded there works in that specific case but before you know it you'll end up trying that on a c-array passed...
