URGENT please help this code is not running properly i need to submit tommorow
Hi so i need to submit this code tomorrow as my school project but its not running properly this is a quiz maker with built in calculator code which can make 2 kinds of quizzes 1)a random quiz in which there can be any random question and 2) a topic wise quiz meaning the user can create topics such as former presidents and the user can write how many ever questions and answers he/she wants in it this code has 3 functions one function is inside of a class that is a calculator code and there are two other functions one is for writing questions and answers into a topic wise quiz and a random quiz and another to read and display them i can write the code both topic wise and the random one and i can also read the random quiz but when i select to read from the topic wise quiz nothing happens the code just stops working i am using turbo c++ 4.0 as my school requires me to use that but i have tried multiple other compilers such as gnu++ in code blocks and many online compilers but same problem occurs even in other compilers you can change the iostream.h and filestream.h to just iostream and fstream and type using namespace std before all the code to make this code run on modern compilers please help me get this fixed!!!
