整数push_back不适用于我的字符串向量

问：

我正在尝试并行推回 3 个向量，当我进入字符串向量时，我收到以下错误：push_back()

no instance of overloaded function "std::vector<_Ty, _Alloc>::push_back [with _Ty=std::string, _Alloc=std::allocator<std::string>]" matches the argument listC/C++(304)
ask3.cpp(38, 8): argument types are: (int)
ask3.cpp(38, 8): object type is: std::vector<std::string, std::allocator<std::string>>

这是我所处的代码块：

#include <iostream>
#include <fstream>
#include <sstream>
#include <vector>
#include <string>
using namespace std;

int main()
{
    int length, count = 0, moviecount = 0, spacecount = 0;
    ;
    vector<int> status, price;
    vector<string> movies;
    string FileName, text, line, dummy;

    FileName = "MovieList.txt";

    ifstream InFile;
    InFile.open(FileName);
    while (!InFile.eof()) {
        getline(InFile, line);
        text += line + "\n";
    }
    cout << text;

    length = text.length();
    for (int i = 0; i <= length; i++) {
        if (text[i] == ' ') {
            spacecount++;
        }
    }
    if (spacecount == 2) {
        moviecount = 1;
    }
    else if (spacecount > 2) {
        int temp = spacecount;
        temp = temp - 2;
        temp = temp / 3;
        moviecount = 1 + temp;
    }
    movies.push_back(moviecount); //<-- problem line
    status.push_back(moviecount);
    price.push_back(moviecount);
}
