I'm writing a basic chess program to calculate how many sets you can make with the given chess figures. The data file:
4
22 3 5 6 2 0
1 1 1 1 1 1
8 4 4 4 1 2
5 3 3 3 0 2
The code:
#include <iostream>
#include <fstream>
#include <vector>
int main
(int argc, char *argv[])
{
std::fstream data_file;
size_t i, k;
std::vector<long> chess;
long t, n;
data_file.open("U1.txt", std::ios::in);
data_file >> n;
for (i = 0; i < n; i++)
chess.push_back(0);
for (i = 0; i < n; i++) {
for (k = 0; k < 6; k++) {
data_file >> t;
std::cout << t << " ";
chess[k] += t;
}
std::cout << std::endl;
}
data_file.close();
for (int i = 0; i < 6; i++)
std::cout << chess[i] << " ";
std::cout << std::endl;
data_file.open("U1rez.txt", std::ios::out);
data_file << n;
std::cout << n << std::endl;
data_file.close();
return EXIT_SUCCESS;
}
The output:
22 3 5 6 2 0
1 1 1 1 1 1
8 4 4 4 1 2
5 3 3 3 0 2
36 11 13 14 3 4
4
Why am I getting 3 and 4 at the end result just after 36, 11, 13 and 14 at line 5? When I print the test values I seem to get the right numbers but something goes terribly wrong in the addition of them in the vector container.
