Structured Programming, if Statements. Create a flowchart and a C++ solution for each of the following problems. For each solution, use only one return 0; statement in main.cpp.

Write a program that prompts the user to enter a number, then prints to standard output the number and a message that states whether the number is less than zero or greater than zero. Sample compilation and runs of the program on a MacBook-Pro are shown below:

MacBook-Pro:Chapter3 jaingber$ g++ Program1.cpp

MacBook-Pro:Chapter3 jaingber$ ./a.out

Enter a value: 9

You entered 9

9 is greater than zero.

MacBook-Pro:Chapter3 jaingber$ ./a.out

Enter a value: −2

You entered -2

-2 is less than zero.

MacBook-Pro:Chapter3 jaingber$ ./a.out

Enter a value 0.5

You entered 0.5

0.5 is greater than zero.

MacBook-Pro:Chapter3 jaingber$ ./a.out

Enter a value 1.602177e-19

You entered 1.60218e-19

1.60218e-19 is greater than zero.
