Question

This is a really simple program I’m writing here but came up to the problem.
well, the program fills the array[2000] from the file and then it should TYPE(cout) the array[i] which isn’t equal to the second member of array. I am not sure how to point to the second member of array in program. here is the piece of program:

#include <iostream>
#include <fstream>

using namespace std;
const int N=2000;

int main() {
    int* array;
    array = new int[N];

    for (int i=0; i<N; i++){
        ifstream ifs("reals.txt");
        ifs>>array[i];
    }

    for (int i=0; i<N; i++){
        if(array[i] != array[1])   /// is this right? is array[1] second member? 
            cout<<array[i]<<'\t';
        if((i+1)%13) cout<<endl;
    }
    system("pause");
    return 0;
}

how will it be, if was I wanted to check for the second element from last element of array?

P.S. sorry for my English. if there is anything you can’t understand, feel free to comment and I will try to explain. thanks in advance.

Answer 1

array[1] is the second member. Your problem is however that you are reopening the file every time in your loop:

for (int i=0; i<N; i++){
    ifstream ifs("reals.txt");
    ifs>>array[i];
}

you need to open the file before the loop:

ifstream ifs("reals.txt");
for (int i=0; i<N; i++){
    ifs>>array[i];
}
