I want get data from the car1.txt file and do the probability calculation but all result is 0.0% ?? just want to ask how to get large number of data from txt file by using array method.
This is my txt file and cpp file

1	1	2	2	3	4	unacc
1	1	2	2	3	3	unacc
1	1	2	2	3	2	unacc
1	1	2	2	3	4	unacc
1	1	2	2	3	3	unacc
1	1	2	2	3	2	unacc

The last column in that file is a string which also must be read

int i = 0;
string stuff;
while( infile >> oldcases[i][0])
{
    for(int j = 1; j < 6; j++)
          infile >> oldCases[i][j];
    infile >> stuff; // read the strings at the end of each line
    ++i;
}

hi , can you tell me that code is put in which part of my code? cause when i put there have the error, then i add #include <string> . and modify some code like
char string stuff;
still got two error occur .

C:\Program Files\Microsoft Visual Studio\MyProjects\CBR1\heart.cpp(19) : error C2146: syntax error : missing ';' before identifier 'stuff'
C:\Program Files\Microsoft Visual Studio\MyProjects\CBR1\heart.cpp(19) : fatal error C1004: unexpected end of file found

Its better to just attach the source code to your post here than to post links to some jpeg file. To do that, just click the "Go Advanced" button then on the next screen "Manage Attachments".

If you want to use the code I posted then delete aht loop just above it. Either that, or ignore the code I posted and just add infile >> stuff; after reading the last integer so that your program also reads the string at the end of each line.
