The typical usage is with CSV-type files, where each line consists of fields separated by a delimiter, specified by the option -d. The default delimiter is the TAB character. Suppose you have a data file data.txt with lines like 0 0 755 1482941948.8024 102 33 4755 1240562224.3205 1003 1 644 12199...

$ cut -d, -f1,3 <<<"a,,b,c,d,e" a,b is rather obvious, but with space-delimited strings it might be less obvious to some $ cut -d ' ' -f1,3 <<<"a b c d e" a b cut cannot be used to parse arguments as the shell and other programs do.

One of the main advantage of std::array as compared to C style array is that we can check the size of the array using size() member function int main() { std::array<int, 3> arr = { 1, 2, 3 }; cout << arr.size() << endl; }

The member function fill() can be used on std::array for changing the values at once post initialization int main() { std::array<int, 3> arr = { 1, 2, 3 }; // change all elements of the array to 100 arr.fill(100); }
