Problem $1($

Two Intervals

$)$

Write a program called

two

intervals.cpp

that accepts

a

$($float$),$

b

$($float$),$

d

$($float$),$ and

c

$($float$)$ as command$-$line arguments.

$$

The two numbers

a

and

b

represent endpoints of a closed interval $($

$[$a$,$ b$]$

when

a

$$

b

$,$ or

$[$b$,$ a$]$

when

a $>$ b

$)$ on real number line.

$$

The two numbers

c

and

d

represent endpoints of a closed interval $($

$[$c$,$ d$]$

when

$[$c

$$

d

$,$ or

$[$d$,$ c$]$

when

c $>$ d

$)$ on real number line.

Your program will verify then concludes whether or not these two intervals instersect each

other.

Also, your program must display the message $$Requires $4$ arguments to run!$$ if the user

passed less than $4$ arguments when running the program.

Here are some example outputs when running the program from a terminal.

g$++-$o out$/$two$\_$intervals.out src$/$two$\_$intervals.cpp $123$

$

$./$out$/$two$\_$interval.out

Requires $4$ arguments to run!

$

$./$out$/$two$\_$interval.out $-2435$

The interval $[-2,4]$ intersects with $[3,5]$

$

$./$out$/$two$\_$interval.out $534-2$

The interval $[3,5]$ intersects with $[-2,4]$

$

$./$out$/$two$\_$interval.out $2468$

The interval $[2,4]$ does not intersect
