• c++ alignment when printing cout << 6 answers

i want output per follows in c++:

name                   aabsd size in kb             170  width , height       512 512  cout<<"\n \t name "<<std::setw(15)<<filename; cout<<" \n \t size in kb "<<std::setw(10)<<size; cout<< " \n \t width  , height  "<<std::setw(3)<<width<<" "<<height; 

values on right side should aligned in same coloumn. tried setw() not give me output aligned because left side text different.

another answer relies on purely c++ specific constructs.

#include <iostream> #include <iomanip>  int main() {    char const* filename = "abcd";    int size = 10;    double width = 20;    double height = 30;     // std::left says align output left when writing next field    // set::setw(20) says use 20 characters next field.    std::cout << std::left << std::setw(20) << "name" << filename << std::endl;    std::cout << std::left << std::setw(20) << "size in kb" << size << std::endl;    std::cout << std::left << std::setw(20) << "width , height" << width << " " << height << std::endl;     return 0; }
