parse

hello everyone, i have a problem. Im reading a .txt file in like this:

Code:

Doe,John           20

it fills the array: list[10]

I would like to put 20 into an integer array, and Doe, John into a string array. can someone give me a hand on the code. Thanks really appreciate it.

You could use scanf or you could make code that reads text up to the first comma (the last name) then reads the string up to the first white-space (first name) reads data after the first white-space and if it is a letter then it must be a middle initial and if it is a number then it must be whatever that number you have in your example indicates.

how do i make it read up to the first space?

Read in a whole line using getline and then parse the string by doing something like:

Code:

string strLine;
getline(inFile, strLine);
int comma = strLine.find_first_of(",");
....

this is what I have so far.

Code:

#include <cstring.h>
#include <iostream.h>
#include <conio.h>
#include <fstream.h>

main()
{
      string strLine;
   	fstream inFile;
		inFile.open("test.txt",ios::in);
		int size;
		size = 0;
		while( !inFile.eof() )
		{
  			getline(inFile, strLine);
  		}
		inFile.close();


	int space = strLine.find_first_of(" ");
   




}

don't know what to do now though

Once you know where the first space char is, you can copy all the chars prior to that into your string array, and the converted int to your int array

i tried this, but it gives me errors.

Code:

#include <cstring.h>
#include <iostream.h>
#include <conio.h>
#include <fstream.h>
#include <stdio.h>

int main()
{
    string strLine;
    fstream inFile;

    inFile.open( "marks.txt",ios::in );
    int size;
    size = 0;
    while( getline( inFile, strLine ) )
    {
        //getline( inFile, strLine );
        cout << strLine << endl;
        int space = strLine.find_first_of( " " );
        cout << "First space at position " << space << endl;
        int res = atoi(&(strLine.c_str())[space]);
        cout << "Converted int is " << res << endl;
        getch();

    }
        inFile.close( );
    char *p;


    p = strtok(strLine, " ");
    cout << p << endl;

    getch();
}

Could i get some help with it.

Why make things so complicated?

Code:

#include<iostream.h>
#define MAX_LINES 20
#define MAX_NAME_LEN 50
int main()
{
    char names[MAX_NAME_LEN][MAX_LINES];
    char buff[64];
    int nums[MAX_LINES];
    Ifstream inFile;
    int i;

    inFile.open( "marks.txt" );
    if( !inFile.is_open() ) return (1);

    for(i=0; !inFile.eof(); ++i)
    {
        cin >> names[i]; // will read up until the whitespace
        cout "Line# " << i << " name: " << names[i];
        cin >> nums[i];
        cout << " number: " << nums[i] << endl; 
        cin.ignore(1);
        cin.get();

    }
    inFile.close( );
    cin.get();
    return (0);
}
