Part $2$ use c$++$ not python or java

Overview

When working with extremely distant celestial objects, astronomers have to work not in hours or days, but years and

centuries. This presents a challenge: Not every year is $365$ days, and sometimes we still want to be exact.

Your task is to write a program that converts a number of years to days. Your program must account for leap years.

To make the calculations easier, we will assume we start on January $1,2001.$ This means:

Every $4$th year $($that would be $2004,2008,...)$ has $366$ days

Every $100$ th year $(2100,2200,$dots$)$ the leap year is skipped, and has $365$ days

Every $400$ th year $(2400,2800,$dots$)$ the leap year skip is skipped, and goes back to having $366$ days $($just as a

regular leap year would$)$

This means that every $100$ years $($from Jan $1,2021),$ there's not $25,$ but $24$ leap years. Moreover, every $400$ years,

there's not $100,$ neither $96,$ but $97$ leap years.

Write a program in your source directory src named ex$1$q$2.$c$.$ This program should take a number of years $($as an

integer$)$ and convert it to days following the above rules. Upon non$-$numerical input, your program must print out

"Error: Invalid input" and exit with a non$-$zero code.

Example I$/$O

Enter number of years since Jan $1,2001$: $3$

$1,095$ days

Enter number of years since Jan $1,2001$: $10$

$3,652$ days

Enter number of years since Jan $1,2001$: $150$

$54,786$ days
