It's not clear what you're asking.

Also, please use the format tags to post formatted code.

[mutexe]

Can put you code in code tags please? And can you be a bit more specific than "it doesn't work here's my code".
Cheers.

edit: this code is also full of compilation errors. can you sort those out first too?

[Jenneyman96]

how to put tags ?

Above your code:

guys my codes is ok just the calculation part i got a bit problem it is showing different output help guys T_T

[MikeyBoy]

If you make your code more readable, then more people will read it. So... use code tags!

I feel psychic.
I guess the effective program is:

int main()
{
  double newtotalamount, totalamount, numshape, numtype, numTopping;
  ofstream myfile("Resit.txt");

  newtotalamount = totalamount + (totalamount*0.7);
  myfile<<"\t\tANY CAKE SHOP\n";
  myfile<<"----------------------------------\n";
  myfile<<"Type of Shape"<<numshape<<"\n";
  myfile<<"Type of Cake "<<numtype<<"\n";
  myfile<<"Type of Topping"<<numTopping<<"\n";
  myfile<<"The Total price of your cake is"<<newtotalamount<<"\n"<<endl;
  myfile<<"Thanks for purchasing \n";
  return 0;
}

I guess the question is:
Why does the program write 2.34777e-317 into the Resit.txt?

If so, then the answer is:
Uninitialized variables

Any attempt to refute with the functions asking input from the user is easy to squash with the what happens in Vegas, stays in Vegas stanza.
