Hello, I am having problems with my program: I need to let the user input a name

Question

Hello,
I am having problems with my program:
I need to let the user input a name and then an initial starting balance (infinite amount of names/balance), storing all of this information so that I will be able to search later for the name to withdraw/deposit/check balance of that specific person. I think I'll need to write to a file and then search but I'm not quite sure how to do that. Also, I need to assign a random userid to each name but for some reason, it generates the same id for all names. Please help me, any tips suggestions will be great! Thank you!

Explanation / Answer

hi there what i see that`s there is a problem with the number generator when u make a variable static in a class all the objects of the class will have the same number no matter what happens the last value will be given to all the objects and to write to a file and close it and open it again i prefers using fstream variable to write to the end of the file and not losing the data inside the file here is an example void main() { fstream out; out.open("test.txt"); out.seekp(0,ios::end);//to make the pointer go to the end of the file out
