Thread: read float array from file

If the size is fixed, it's really easy

Just a nested loop.

Code:

#include <fstream>
#include <iostream>

const int numRows=3;
const int numCols=3;

int main() {
	std::ifstream in("data.txt");
	float tiles[numRows][numCols];

	for (int i = 0; i < numRows; i++) {
		for (int j = 0; j < numCols; j++) {
			in >> tiles[i][j];
			std::cout << tiles[i][j] << ' ';
		}
		std::cout << '\n';
	}

	return 0;
}

If it's not a fixed size, the problem with bigger distraction will be allocating the 2d array.
