Issue
I am working with vectors and I wanna know how I can print the empty spaces in between until the line ends.
void print_vector(const std::vector < int > & v, int print_cols, int col_width) {
//dash
cout << string(print_cols * (col_width + 2) + 1, '-');
cout << endl;
//printing the vector in formated output
cout << "|";
for (size_t x = 0; x < v.size(); x++) {
cout << right << setw(col_width) << v[x] << " |";
//prints new line if it reaches limit of numbers per line
if ((x + 1) % print_cols == 0) cout << endl << "|";
}
//dash
cout << endl << string(print_cols * (col_width + 2) + 1, '-');
cout << endl;
}
this is my current output: my output so far and sorry I can't embed images yet it wont let me. But this is the output that I want output needed
Solution
void print_vector(const std::vector < int > & v, int print_cols, int col_width) {
//dash
cout << string(print_cols * (col_width + 2) + 1, '-');
cout << endl;
//printing the vector in formated output
cout << "|";
size_t x = 0;
for (x = 0; x < v.size(); x++) {
cout << right << setw(col_width) << v[x] << " |";
//prints new line if it reaches limit of numbers per line
if (x < v.size() - 1) {
if ((x + 1) % print_cols == 0) {
cout << endl << "|";
}
}
}
size_t remain = print_cols - (x % print_cols);
for (size_t i = 0; (remain != print_cols) && i < remain; ++i) {
cout << right << setw(col_width) << " " << " |";
}
//dash
cout << endl << string(print_cols * (col_width + 2) + 1, '-');
cout << endl;
}
Sample outputs:
-------------------------------------------------
| 1 | 2 | 3 | 4 |
| 5 | 6 | 7 | 8 |
| 9 | | | |
