Write a $C++$ program that reads an integer, denoted as $N,$ from the input, issues an error message if $N$ is negative and generates the following output otherwise.

$1,3,5,$dots,$2n-3,2n-1$

$1,3,5,$dots,$2n-3,$

dots,

$1,3,5,$

$1,3,$

Develop a $C++$ program that takes an input for the variable $N$ and computes the value of $$ number $()$ the sum of the initial $N$ terms of the following series. Subsequently, display the result in the output.

$=4-\frac{4}{3}+\frac{4}{5}-\frac{4}{7}+\frac{4}{9}$dots

Write a function in $C++$ called MinimumDigit that takes an integer as a parameter and finds and retu smallest digit.

Find the output of the following $C++$ program.

#include $i=1$;$i<mn\; id="EditorElement\_13067301">8</mn>$;
