我很新的編程,需要一些幫助,謝謝!我需要通過一個ifstream到一個函數,所以我可以將它添加到一個向量
我有一個名爲namelist.txt的文本文件。我需要將inFile傳遞給一個函數,該函數可以將名稱列表(以firstname lastname的格式,例如:chuck norris)添加到名爲vecStudent的矢量中。你如何將文件傳遞給一個函數,如果可能的話,我如何將這些名稱添加到一個矢量中?
#include <iostream>
#include <fstream>
#include <string>
#include <vector>
using namespace std;
ifstream readtoVec(); //function prototypes
int displayAll();
int add();
int remove();
int savequit();
int main()
{
char cInput;
string strFileName;
vector<string> vecStudent;
ifstream inFile;
ofstream outFile;
{
cout << "Please Enter the data file name (with location): ";
cin >> strFileName;
inFile.open(strFileName.c_str());
if (inFile.fail())
{
cout << "Input file error!" << endl;
return -1;
}
// call a function to read the contents of the input file into vecStudent
else
{
readtoVec (ifstream& inFile);
我收到這裏所說的錯誤 「類型名稱是不允許的」
}
while (true)
{
cout << "--------------------------------------" << endl;
cout << " Student Record - Main Menu " << endl;
cout << "--------------------------------------" << endl;
cout << " Enter 1 to display ALL students " << endl;
cout << " Enter 2 to add a student name " << endl;
cout << " Enter 3 to delete a student name " << endl;
cout << " Enter 4 to SAVE and quit the program " << endl;
cout << "--------------------------------------" << endl;
cout << " Enter menu option: " ;
cin >> cInput;
switch (cInput)
{
case '1':
//call function
break;
case '2':
//call function
break;
case '3':
//call function
break;
case '4':
//call function
return 0;
default:
cout << "invalid input" << endl;
break;
}
return 0;
}
感謝您的回覆,我將如何將.txt文件中的名稱列表添加到函數readtoVec中的向量?我認爲虛空不會返回任何東西,然後主要。 – 2012-04-09 19:54:16
