Dear All,
I have basic structure of the C++ code [1]. It suppose to read particular columns from some txt file. The txt file look like following [1] (snippet). I have to ask the details for instance 'id' information for rows satisfying text with red color. The issue is that the txt file has not just the column wise data but other stuff as well, as you can check the [2]. Besides, the most important is I need to select data only for columns with [COLOR="rgb(255, 0, 255)"]phase[/COLOR] has certain value.
Thanks in advance,
emily,
ISSUEs facing:
a.) if there are top line with the
Code:
number side id id_2 phase particulers cost phase
, it is acepting. Else if more than one such line is there, its not working.
b.) When I perform test with small file of some 500 lines, and tried to cout. It fail with
Code:
Segmentation fault (core dumped)
c.) The TASK is to plot
Code:
id vs id_2
for certain condition being true, please check the BLUE text in the code
[1]
-----------------------------------------------------
Code:
#include <iostream>
#include <stdlib.h>
#include <string>
usign namespace std;
int main(int argc, char *argv[]){
int number[2600], side[2600] , id[2600] , id_2[2600] , phase[2600] ,cost[2600], phase[2600],
string particulers[2600];
string fileToOpen = argv[1];
if(argc!= 1 || argc < 2) {
cout<<"Error :check the no of input, require input.txt "<<endl;
exit(0);
}
//open the file
ifstream inFile(fileToOpen.c_str());
if(!inFile.is_open())
{
cout << "Problem opening the file. Program terminating." << endl;
exit(EXIT_FAILURE);
}
while(!inFile.eof()){
inFile.ignore(numeric_limits<streamsize>::max(), '\n');
inFile >> number[i] >> side[i] >> id[i] >> id_2[i] >> phase[i] >> particulers[i] >> cost[i] >> phase[i] ;
if (particulers[i].compare("top") == 0 && phase[i] == 0 ){
// PLOT (id vs id_2)
}
i++;
}
i--;
}
}
Hi ahamed,
I want to plot two variables for certain condition being true. I will decide it itself in the code for which conditions I would like to plot the variables for.
Please check the modified code and TASK that I have added in the original message.
The file is really huge and it so far not working.
