Whenever I tried to enter a fruit and its properties in the buyer option and then tried to access it to the seller option, only the "amount" and "price" are being displayed. (I have tried using array of characters and it worked, but when I use string it doesn't work).
These three variables:
fruit obj1;
seller obj2;
buyer obj3;
are created from scratch everytime you loop. Hence the values you enter in iteration 1 are not preserved in the second iteration. The fact that you are getting price and amount correctly is just a coincidence.
To fix this quickly, just move the variables above outside the loop:
fruit obj1;
seller obj2;
buyer obj3;
cout <<"Welcome to shop simulator!" <<endl;
while(true){
