For this daily, write a program that will calculate and display the sum of the values between a lower and upper

bound, inclusive.

A CPP file $($sum$\_$boundary.cpp$)$ has been provided. It contains the declaration for an integer variable $($lower$),$ the

declaration for a second integer variable $($upper$),$ code that will ask the user to enter the lower bound, and code

that will ask the user to enter the upper bound.

Add code that will check that the lower and upper bounds are valid. To be valid, the lower bound must be less

than or equal to the upper bound. If the boundary values are invalid, swap the boundary values and display a

message that the boundary values have been swapped. The message that is displayed MUST match the message

that is displayed in the output below $($print a new line at the beginning and end of the message$).$

Once the boundary values are valid, calculate the sum of the values between the lower and upper bounds,

inclusive. Display the sum as follows:

The sum of the values between $[$lowerbound$]$ and $[$upperbound$]$ is $[$result$]$

where $[$lowerbound$]$ is the valid lower bound value, $[$upperbound$]$ is the valid upper bound value, and $[$result$]$ is

the calculated sum.

Print a new line at the beginning and end of the output.
