error: no matching function for call to ‘std::vector<std:

Question

我写 func 将字符串从文件写入向量并出现错误

error : error: no matching function for call to ‘std::vector<std::__cxx11::basic_string<char> >::push_back(std::ifstream&)

代码：

//parse file file

#include <fstream>
#include <vector>

const unsigned short numOfStrings=5;

void ReadFromFile (std::ifstream& thisin, std::vector<std::string>& thisData)
{
    thisData.push_back(thisin);
}

int main ()
{
}

Answer 1

您正试图将 ifstream 推入向量，而不是从中读取。

要从 ifstream 读取，您可以执行以下操作。

void ReadFromFile (std::ifstream& thisin, std::vector<std::string>& thisData)
{
    std::string word;
    while(thisin >> word)
    {
        thisData.push_back(word);
    } 
}
