How can I output data to the console in a table in C++? There's a question for this in C#, but I n开发者_StackOverfloweed it in C++.
This, except in C++: How To: Best way to draw table in console app (C#)
Here's a small sample of what iomanip has:
#include <iostream>
#include <iomanip>
int main(int argc, char** argv) {
std::cout << std::setw(20) << std::right << "Hi there!" << std::endl;
std::cout << std::setw(20) << std::right << "shorter" << std::endl;
return 0;
}
There are other things you can do as well, like setting the precision of floating-point numbers, changing the character used as padding when using setw, outputting numbers in something other than base 10, and so forth.

I couldn't find something I liked, so I made one. Find it at https://github.com/haarcuba/text-table
Here's an exmaple of its output:
+------+------+----+
| |Sex | Age|
+------+------+----+
|Moses |male |4556|
+------+------+----+
|Jesus |male |2016|
+------+------+----+
|Debora|female|3001|
+------+------+----+
|Bob |male | 25|
+------+------+----+
Can't you do something very similar to the C# example of:
String.Format("|{0,5}|{1,5}|{2,5}|{3,5}|", arg0, arg1, arg2, arg3);
Like:
printf("|%5s|%5s|%5s|%5s|", arg0, arg1, arg2, arg3);
Here's a reference I used to make this: http://www.cplusplus.com/reference/clibrary/cstdio/printf/
Check the column value length and also keep the length of value in mind to format.
printf(" %-4s| %-10s| %-5s|\n", "ID", "NAME", "AGE");
See how MySQL shell interface was designed, it will give you a good idea.
