Question #3012

Write a main function that allows the user to insert a number and allows him to test the number where the number is;

1.+ve,-ve.

2.iteger,rational

3.even or odd

4.for all of theabove.

Use an if statement to determine what the user want to do.

what do you want todo.

1.check sign of the number .

2.check rationality .

3.check for allthe above.
