Hello,
     please, asap, provide me with any possible ideas, hints or ,in detail,solutions to the following program:-

* Write a pascal program to input two real numbers and give the user the choice to adding, subtracting, multiplying or dividing these numbers. Perform the appropriate calculation and display the result. Your program should trap any attempt to divide by zero.

We have covered the For,repeat,While,and case statements, and arrays.
