C++ STL之向量vector

/*vector_example.cpp*/
#include <iostream>
#include <vector>
#include <string>

using namespace std;

int main() {
    vector<string> msg = {"Hello", "C++", "World", "from", "VSCode", "and the C++ extension!"};

    for (const string& word : msg) {
        cout << word << " ";
    }
    cout << endl;

    return 0;
}

• vector.size() 返回向量中元素个数
• C++中的std::string可以视为std::vector<char>类型的向量，因此可以用.size()函数返回字符串的字符长度（不含'\n'结尾符号）。
