using namespace std;

int main() {

int num_cols = 0;

int num_rows = 0;

vector sizeCheck;

vector > dataInput;

vector> Rvals;

vector> Gvals;

vector> Bvals;

string ele_File = "";

cin >> num_cols >> num_rows;

ifstream inputFile;

inputFile.open("map-input-100-100.dat");

if (!inputFile) {

cout << "Error: Unable to open file";

return 0;

}

for (int i = 0; i

{

for (int j = 0; j < num_cols; j++)

{

inputFile >> dataInput.at(i).at(j);

}

inputFile.close();

return 0;

Explanation / Answer

#include<iostream>
#include <vector>
#include<fstream>

using namespace std;

int main() {
int num_cols = 0;
int num_rows = 0;
vector<int> sizeCheck;
vector <vector<int> > dataInput;
vector<int> Rvals;
vector<int> Gvals;
vector<int> Bvals;
string ele_File = "";
cin >> num_cols >> num_rows;
ifstream inputFile;
inputFile.open("map-input-100-100.dat");
if (!inputFile) {
cout << "Error: Unable to open file";
return 0;
}
for (int i = 0; i<num_rows; i++)
{
for (int j = 0; j < num_cols; j++)
{
inputFile >> dataInput[i][j];
}
}
inputFile.close();
return 0;
}
