using namespace std;
#include<string>
#include<queue>
#include<vector>

int main()
{
    string str = "He loves her";
    vector<queue<char>> vs;
    int sz = str.size();
    int i = 0, count = 0;
    while (i < sz) {
        while (str[i] != ' ') {
            vs[count].push(str[i++]);
        }
        count++;
        i++;

Answer 1

 string str = "He loves her";
    int sz = str.size();
    vector<queue<char>> vs(sz);
    int i = 0, count = 0;
    while (i < sz) {
        while (str[i] != ' ') {
            vs[count++].push(str[i++]);
        }
        //count++;
    }
