Please help I am confused to where start. It C++ program thankyou

The stoi function converts a string to an integer, but does notcheck whether or not the value of the string is a good integer. Ifthe stoi function fails, an exception is thrown and the programterminates.

Write a program that asks the user to enter two strings, onecalled sNumerator and the other sDenominator. Using the stoifunction, convert the two strings to numbers but individually catchany exceptions and send a message back to the user that the numbersthey entered were not valid. If both convert successfully tonumbers, divide the numerator by the denominator and catch theexception where the denominator is zero. (You CANNOT check for zerousing an if statement before doing the calculation). If theexception is thrown, notify the user that you cannot divide by zerootherwise display the calculated fraction.
