如何反转字符？

Answer 1

此代码将反转vector<string>

的所有字符串元素

#include <string> 
#include <algorithm>

void main()
{
    vector<string> a = { "abc", "pqr", "xyz" };
    for (auto& s : a)
    {
        reverse(begin(s), end(s));
    }
}

Answer 2

void reverse(string& s)
{
    int i = 0, j = s.length() - 1;
    while(i < j)
    {
        swap(s[i++], s[j--]);
    }
    cout << s << endl;
}

在main（）中：

reverse(theWords[0]);
reverse(theWords[1]);
//.....
