Write a program that calculates the area of some simple figures (i.e. a square and a rectangle). One function per figure. Check if the function arguments are greater than 0 – if they aren't, throw an exception. This program should use your own exceptions to communicate with a higher-level code. Add some attribute in your exception to pass a message to the user. Some boilerplate code is included below.

pls help answer this question in c++

Lab 7.2.1 Exceptions: catch block Objectives Familiarize the student with: • handling exceptions; writing his/her own exception classes; • passing additional information in exceptions; Scenario Write a program that calculates the area of some simple figures (i.e. a square and a rectangle). One function per figure. Check if the function arguments are greater than 0 – if they aren't, throw an exception. This program should use your own exceptions to communicate with a higher-level code. Add some attribute in your exception to pass a message to the user. Some boilerplate code is included below. #include <iostream> using namespace std; //add your own exception class here //add functions code here int main(void) { float a, b, r; cin >> a; cin >> b; try { square_area(a); rectangle_area(a,b); float rsquare float rrectangle cout <« rsquare << endl « rrectangle << endl; } //add a suitable catch block here return 0; Example input 2 1 Example output 4 Page 1 / 1 + -
