Compliling C++ program in Visual Studio using g++ compiler generates % at the end

When compiling my program in Visual Studio Code using the g++ compiler, the output generated has the % sign.

#include <iostream>

int Main() {
  std::cout << "Hello World!";
  return 0;
}

I have deleted the question mark, so I think there is no control character.

Solution

  • On POSIX compliant systems, individual lines are by convention delimited by a newline character. zsh (which is the shell you’re using) uses % to indicate output that’s missing that terminating newline character.

    Try entering echo -n hello on your shell to replicate the behaviour.

    To fix this (and remove the % output), add a newline to your code’s output:

    …
std::cout << "Hello World!\n";
